How could you increase the atomic number?
Answer:
So the atomic number increases with each element. The atomic mass is the sum of the protons and neutrons. As the atomic number increases it causes an increase in the atomic mass. However sometimes there is not a corresponding increase in the number of neutrons...

why is it true that particles in a rock lying on the group have kinetic energy and energy
Answer:
Particles of objects have both kinetic and potential energy. Because particles are constantly in motion, they have kinetic energy. These particles are arranged in specific ways in different objects. Therefore, they also have potential energy.

Information to make scientifically supported judgments by describing the Importance of Ernest Rutherford's gold-foil experiment.
Answer:
Rutherford's experiment led to the rejection of JJ Thomson's raisin bundle model. In the experiment, a thin gold strip was bombarded with alpha particles. According to Thomson's atomic model, all alpha particles should have passed through the strip, but in this experiment it was found that some of the particles were reflected backwards. Based on his experiment, Rutherford published the result that almost the entire mass of an atom is concentrated in its nucleus. Rutherford's atomic model was later improved by Niels Bohr, who published the Bohr model.

This distance-time graph represents a journey made by Jo (image above)
At what speed was Jo walking for the first 30 minutes?
(in km/h)
Answer:
1 km per 10 minutes
Explanation:
Based on the map that's my conclusion
Answer:
It's actually 6 km/h and for b) it's 10 minutes
Explanation:
At 30 minutes the distance was 3km, so you multiply it by 2 to get 6km.
And then it's 10 minutes for part B)

what can be said about the properties of a compound?
Answer:
A compound has unique properties that are distinct from the properties of its elemental constituents. One familiar chemical compound is water, a liquid that is nonflammable and does not support combustion. It is composed of two elements: hydrogen, an extremely flammable gas, and oxygen, a gas that supports combustion.
