Bromine is the only non metal that exists in liquid state at the room temperature.
Bromine belongs to the member of halogen group. Heavy, volatile, mobile etc are some of the characteristics of it. Bromine is quite dangerous.
It has red brown color at room temperature. It is very reactive as it evaporates quickly to form a similar colored gas.
Bromine molecules depicts strong inter-molecular force so that's why it doesn't evaporates at room temperature. It also shapes up diatomic molecules and Van Der Walls interactions are highly strong.

Explanation:
compare the size of ions to the size of atoms from which they form
The negative ion is always significantly bigger than the atom it originated from. In actuality, the negative ion may be larger than the neutral atom by a factor of more than two.
Ions are defined as atoms that gain or lose electrons. When an atom receives or loses its outermost electron, its size (or radius) changes. This change is known as the ionic radius (s). A negatively charged ion known as an anion is created when an atom receives an extra electron, increasing its ionic radius. Positive ions are smaller than their parent atoms, whereas negative ions are bigger. Trend over a time period: Moving across the table from left to right causes the ionic radius to shrink. In any given period, negative ions are always bigger than positive ions.

Explanation:
Which relationship is true of an uncharged atom? the number of protons is equal to the number of electrons.
The relationship that the number of protons is equal to the number of electrons is true for an uncharged atom of an element.
Electrons are negatively charged particles with a negligible mass. These negatively charged particles revolve around the nucleus in discrete orbits called shells.
Protons are positively charged particles which have a mass of approximately 1 amu (atomic mass unit). These positively charged particles are present in the center of the atom, inside the nucleus.
When an atom has an equal number of negative (the electrons) and positive (the protons) electric charges, it is called an uncharged atom. As a result of which, the atom's total electric charge is NIL (zero), and hence it is said to be neutral. For example, a carbon atom includes six protons and six electrons, so it's an uncharged carbon atom with an atomic number of 6.
Therefore, all the elements in the periodic table are atoms in their neutral form.
Thus examples of uncharged atoms would be all neutral atoms, such as Nitrogen atom, Oxygen atom, Hydrogen atom, Sulphur atom, Potassium atom, etc.

Textbooks that have a greater gravitational pull are 4kg textbooks and the distance of objects that have a greater gravitational pull is 2cm.
Newton's law of gravity is Newton's conclusion that the gravitational attraction acting between two objects is proportional to the mass of each object and inversely proportional to the square of the distance between the two objects. So, a 4kg textbook will have a greater gravitational pull than a 2kg textbook.

How is 2 ATP produced in the Krebs cycle?.
2 ATP produced in the Krebs cycle from each pyruvate molecule during the conversion of succinyl-CoA to succinate.
In the presence of the enzyme succinyl CoA synthetase, Kreb's cycle only generates 1 molecule of ATP from each pyruvate molecule during the conversion of succinyl-CoA to succinate.
Glycolysis converts one glucose molecule into two pyruvate molecules, both of which enter the Kreb's cycle at the same time.
Thus, when one glucose travels through aerobic respiration, 2 ATP are ultimately created from Kreb's cycle through substrate-level phosphorylation.
The reduced coenzymes NADH and FADH₂ work as intermediary chemicals in the citric acid cycle to supply protons and electrons to the electron transport chain.

Can someone give me a grade for this essay:
Research and investigate the use of chlorine in water treatment, include both chemical and ethical aspects.
What I wrote:
How it works:
Chlorine serves as a method to further purify water, it can do this by killing the microorganisms that can cause disease (pathogens) that are still left after the sterilisation by breaking down the lipids that make up their cell walls and reacting with the enzymes and proteins inside, deeming them as unusable.
Why is chlorine a great chemical to use in water treatments?
The main sources of water are seas, rivers, and lakes. Living near one of these sources can help get water, but for countries in Sub-Saharan Africa even living near these sources will not help as the methods you have to then purify are not reliable or not safe enough. In countries which are in this economic state with poor water quality, the number of deaths and illnesses caused by badly disinfected drinking water means that the by-products (also known as carcinogens) caused when chlorine reacts with chemicals in the water or in the body become less of a priority. Due to the great amount of poverty in this region, chlorine is a great option due to its price and accessibility, the average price for a water well is around 8,000 USD (£ 6,455.76) , whereas the average price for a chlorination service comes in at around £300-1500 depending on the requirements and the size of the water system that needs to be chlorinated.
To conclude what was said, although chlorine does come with its limitations just like every other method, disinfection by chlorine is still the best guarantee of microbiologically safe water, especially in countries in this region.
Why chlorine is not the best chemical to use in water treatments?
Chlorine is a highly effective method of disinfection. However, when travelling in pipes, if the source of water has higher levels of germs, they could react with chlorine which could produce small amounts of toxic chemicals called DBP’s (by-products) .
Another reason why chlorine is not the best chemical to use in water treatments is because the conditions need to be very specific for chlorine to work optimally; the pH needs to be just right as well as the temperature of the water which needs to be 18 degrees Celsius of higher, decreasing the temperature would increase contact time, the process must therefore be adapted to take into account all of these factors which can be a lengthy process and extremely hard to achieve, putting people at risk in their own homes.
Other effects that it can have on humans is that it has been reported that asthma can be triggered by exposure to chlorinated water . Episodes of dermatitis have also been associated with exposure to chlorine and hypochlorite.
Methods that could be used instead are: UV radiation, Ozonation, Reverse Osmosis, Sodium Ferrate and many more. All of these have their advantages and disadvantages, but the one that seems most like chlorine and has possibly the least amount of toxic products left after being used is Sodium Ferrate, which is capable of decomposing many toxic chemicals into less toxic products and destroying microorganisms. This new reagent also doesn’t form toxic substances in the process of water purification and scientists believe that it can also neutralise chlorine in water. This process is believed to be useful in countries with developed sewage systems, as well as regions requiring local treatments for drinking and wastewater.
Conclusion
In Conclusion, to sum up all the points made, I think that Chlorine is a great way for developing and poor countries like Yemen and Kenya to use, as it can be easily accessed and isn’t too expensive compared to other methods of sterilising and purifying water for example; water wells or boreholes, but, in countries like America and other developed countries I think Chlorine is not a necessity but a want because countries like that can get easier access than other countries to UV radiation, Ozonation, Reverse Osmosis, and Sodium Ferrate due to having an economy which is a lot more stable and has the money to afford these, and of course all of these methods still come with their benefits, limitations and of which can also be more expensive, but on the other hand has they have the same if not better results to chlorine.
It is difficult to give a grade out of 100 without knowing the specific requirements and grading criteria for the essay. However, this essay presents a clear understanding of the topic of chlorine in water treatment, providing a well-rounded discussion on both the chemical and ethical aspects of using chlorine. The essay presents a clear introduction, body, and conclusion and uses specific examples to support the claims made. The writing is clear and easy to understand, and the essay is well-organized and flows well. However, it would be beneficial if the essay would have had a stronger thesis statement and a more detailed conclusion. Overall, this essay would likely receive a high grade.
