To determine the electrical neutrality of an atom, we need to consider the balance between protons and electrons. Protons carry a positive charge, while electrons carry a negative charge. For an atom to be electrically neutral, the number of protons must be equal to the number of electrons.

Given that the atom has 4 protons, we can determine the number of electrons required for neutrality. Since each proton carries a positive charge of +1, the atom needs 4 electrons with a negative charge of -1 to balance the positive charges.

Therefore, the atom will be electrically neutral if it contains 4 electrons.
