What is the charge of an atom that has four protons, four neutrons, and five electrons?


Atoms are composed of protons, neutrons, and electrons. Protons have a positive charge, neutrons have no charge, and electrons have a negative charge. The total charge of an atom is determined by the balance of protons and electrons. In this case, the atom has four protons (positive charge) and five electrons (negative charge), resulting in a net charge of -1, making it a negative ion.

Isotopes are atoms of the same element that have the same number of protons but different numbers of neutrons. A neutral atom has an equal number of protons and electrons, resulting in no net charge. A positive ion would have more protons than electrons, leading to a positive charge.
