Answer:
Bubbles are comprised of gases, which have a lesser density than water. Since they are less dense, they get pushed up to the surface, and they rise, lighter than the liquid around them. This is just like helium in air; helium is lighter than air, so it rises, pushed to the top by the pressure around it.

Answer:
Atomic number = 16, Atomic mass = 34, Net charge= +3
Explanation:
i) Atomic number = Proton number = 16
ii) Atomic mass = Proton number + Neutron number
= 16 + 18 = 34
iii) Net charge= Proton number = Electron number (when element is in ground state or unreacted state)
But, proton number (16) is not the same as electron number (13), this means the element has lost 3 electrons
Thereore, the net charge is = 16-13
= +3
