The electron shell electron in a molecule are depicted in an extremely simplified manner by a Lewis Structure.
How are orbitals filled with electrons?The principle states that electrons are supplied to the various subshell in descending order of increasing energy. In order to access higher energy orbitals, electrons must first fill the least energy orbital that is available to them. Only then do they go on to greater energy orbitals.
What is it mean to fill orbitals from the top down or from the bottom up?According to this, electrons are placed in atomic orbitals in sequence of increasing orbital energy level. The Aufbau principle states that atomic orbitals that are available and have the least energy levels get filled before those that have higher energy levels.

Coordination isomerism in compounds containing both anionic and cationic complexes can be considered to occur by the exchange of some of the ligands from cationic to anionic moieties. Therefore, there are two complex compounds bonded together, one with a negative charge and the other with a positive charge.
Explanation of coordination isomerismIn coordination isomers, the anion and cation complexes of the coordination compound exchange one or more ligands. For example, the compounds [Co(NH3)6] [Cr(C2O4)3] and [Co(C2O4)3] [Cr(NH3)6] are coordination isomers.

Energy is the energy required to destabilize existing chemical bonds and initiate a chemical reaction.
Activation energy is the amount of energy needed to break down already-existing chemical bonds and start a chemical reaction.
What is the name of the energy necessary to weaken existing chemical bonds and initiate a chemical reaction?Collisions must have enough energy (kinetic energy) to break chemical bonds in order to start a reaction. This energy is referred to as the activation energy.
All chemical processes, even exothermic ones, require activation energy to begin. Reactants need activation energy in order to move together, overcome repelling forces, and begin forming connections.
Chemical energy and activation energy are the two different types of energy that are used in chemical reactions. - The activation energy is the quantity of energy needed to initiate a chemical reaction. - If the energy level is lower than the activation energy, the reaction won't occur.

An electron in the n = 6 level emits a photon with a wavelength of 410. 2 nm. To what energy level does the electron move?.
The electron will move to 2nd energy level as n = 2
What are energy levels?An energy level (also called an electron shell) is a fixed distance from the nucleus at which an electron can exist. Electrons are small, negatively charged particles in atoms that move around a central, positive nucleus. Energy levels are a bit like stair steps. The energy emitted at a particular transition is equal to the energy difference between the two energy levels.
E(n) = −1/n² × 13.6eV
For the given case,
λ = 410.2 nm
h = 6.62 × 10⁻³⁴ j h⁻¹
c = 3 × 10⁸
E = hc/λ
E = 6.62 × 10⁻³⁴× 3 × 10⁸/410.2 × 10⁻⁹
E = 0.048 × 10⁻¹⁷ joules
E = 2.99 eV
E = -13.6 1/n²
Since, n = 6
E = -13.6 1/6²
E = -0.38 eV
ΔE = E₂ - E₁

Do any water molecules become gas particles when the vapor pressure is lower than atmospheric pressure?.
Yes. The water molecules will become gas.
Vapour will in fact always escape the liquid phase regardless of what the atmospheric pressure because there is always an always a fraction of molecules in the liquid that will have enough energy to escape from the attractive forces that bind them to the liquid. As the temperature increases, the rate of escape will increase as this energetic fraction increases.
Atmospheric pressure does not affect the rate of escape at all. However, the rate of escape from liquid to gas is not the rate of evaporation.
The rate of escape is counteracted by vapour re entering the liquid and the rate evaporation is the difference. The rate of reentry is controlled by the concentration of vapour in the gaseous phase.

Salt water is more dense than fresh water. A ship floats in both fresh water and salt water. Compared to the fresh water, the volume of salt water displaced by the ship is less.
For floating objects, the weight of the displaced fluid equals the weight of the object. For a more dense fluid, less of that fluid needs to be displaced to create a fluid weight equal to the weight of the object. Since the salt water is more dense, it will not need as much displaced.
The overall density of the ship is less than the density of the water. A ship is constructed to be watertight. Because it is watertight, the metal is able to enclose a volume of air sufficient to lower the average density to less than 1. If it were not watertight, the water would rush in, displace the air, and because metal is more dense than water it would not float.
