Every atom tends to form configuration of noble gas , with the 8 electrons in valence shell.
Answer:
The energy of the particles increase and the molecules move more quickly.
Explanation:
The molecules are moving from a solid (barely moves, molecules close together) to a liquid (molecules slide past each other and take any shape), so molecules are moving more and have more energy
I think the charge is +2
Hope this helps
Increase in heat, molecules start to escape and it turns to vapor
