[URGENT. WILL GIVE BRAINLIEST] Metals, like sodium, tend to lose electrons while nonmetals, like chlorine, tend to gain electrons. Explain why this happens using Coulomb's Law.

Nonmetals tend to gain electrons in order to achieve a full outer shell, so they are said to have high electronegativities. Alkaline metals, for example, would find it much easier to lose electrons than gain electrons, so they are not very electronegative. On the other hand, halogens such as chlorine only need to gain one electron to form a full outer shell. This is much easier than losing seven electrons instead. Metals will lose electrons to become cations, while nonmetals will gain electrons to become anions. Coulomb's law describes the force of attraction between the cations and anions in an ionic crystal.

in chemistry, a solution’s concentration is how much of a dissolvable substance, known as a solute, is mixed with another substance, called the solvent. the standard formula is c = m/v, where c is the concentration, m is the mass of the solute dissolved, and v is the total volume
