Are exchanged or shared during the formation of a chemical bond. a) orbitals b) sublevels c) valence electrons d) subatomic particles

C) Valence electrons.

Explanation:

When a chemical bond is formed it is the electrons that are shared and it is they that hold the two atoms together due to the coulomb forces between the positive nuclei and the valence electrons. To put in in another way, both nuclei of the bond want the electrons, but neither can get them, regardless, they hold on to them, and this is what makes a chemical bond.

the answer is false. this is because for ice to melt, it requires latent heat of melting. latent heat means heat energy required to change phase without any increase in temperatures. therefore, the ice will take energy from the environment to melt hence atmospheric temperatures will reduce.
