C. Also just look up a chemical equation balancer calculator next time.
1) The trails left by an electron as it moves around the nucleus
The electron model dictates that the electrons have no fixed position so it traces their path.
2) 8
Atomic number is equivalent to proton number
3) Its mass is lowered, but it is still the same element.
The element's identity is due to the number of protons; however, neutrons play a large role in an atom's mass. Thus, the mass will decrease but the element will be the same. Such variants are called isotopes.

Polar or ionic substances dissociate into ions when dissolved in water.
<h3>What substances dissociate into ions when dissolved in water?</h3>
Ionic substances dissociate into ions when dissolved in water because water is also a polar by nature. We know that like dissolve like so polar substances dissolve in water and dissociate into ions i.e. positive an negative ions.
So we can conclude that polar or ionic substances dissociate into ions when dissolved in water.
