An atom has (+2) charge, if it has 12 electrons, what is its atomic number?

14.

Explanation:

Electrons have a negative charge, and since the atom has a charge of (+2) it would mean there are 14 protons. (2 more than the amount of electrons, to create a positive charge).

Protons also determine the Atomic number so, the atomic number is 14.

Amount of protons = atomic number.

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.
