Electrons are important to electric current because they are able

carry a positive charge with them as they are transferred from one atom to the next creating electric current.

change from a positive charge to a negative charge when transferred from the one atom to the next as the atom becomes an ion.

move from one atom to another; the atom that looses an electron becomes positively charged and the atom that gains an electron becomes negatively charged.

shift from one atom to another creating a change in the charge of the atom from a negative to a positive.

The answer would be:

Move from one atom to another; the atom that looses an electron becomes positively charged and the atom that gains an electron becomes negatively charged.

It is the movement of electrons from on atom to another that enables elements to form chemical bonds. If electrons do not move, they are shared. The atom that loses an electron becomes positive because it would have less electrons than protons. The atom that accepts the electron becomes negative because it would have more electrons than protons.

Just remember that all elements are neutral, or they have the same number of protons and electrons. They become charged when they lose or gain one.

a, c, d, e are all applying about success strategies.
