Collisions covalent bonding level 16!!!

Group 16 elements tend to form two covalent bonds because they have six valence electrons and need two more to have eight. Oxygen is a group 16 element, and it can gain the same electron configuration as neon if it makes two covalent bonds. It tends to form either two single covalent bonds or one double covalent bond.

answer

fusion: the energy source of stars. the energy released from the collapse of the gas into a protostar causes the center of the protostar to become extremely hot. when the core is hot enough, nuclear fusion commences. fusion is the process where two hydrogen atoms combine to form a helium atom, releasing energy.
