What subatomic particles are involved if 2 atoms come and interact with each other?
(a)
The capacity to cause change.
(a)

negatively charged atom. A HYDROGEN atom covalently bonded to one electronegative atom is also attracted to another electronegative atom.
(a)

it gains energy
energy stays the same
cannot be determined
when an electron moves farther away from the nucleus...
it loses energy
it gains energy
energy stays the same

The SHARING of a pair of valence electrons by 2 atoms (causes partially + or - charge)
(a)
The atoms share the electron EQUALLY.

electrons in a covalent bond.
