Ionic bonds form as a result of the electrostatic attraction between
Andrews [41]

Answer:

Ions

Explanation:

Ionic bonds are formed when an element loses electrons (usually a metal), and other elements gain these electrons(usually a nonmetal or the hydrogen). When the element loses electrons, it becomes a cation, an ion with a positive charge; and when the element gains electrons it becomes an anion, an ion with a negative charge.

The charge in the ions produces an electrostatic attraction between them, and that attraction is the force that gets them together in a bond.

CH3NH2 + HOH ==> CH3NH3^+ + OH^-Which molecule/ion accepts a proton. That is the base. Which molecule/ion donates a proton. That is the acid.

A stable subatomic particle known by the symbol for "proton"

e elementary charge, p, H+, or 1H+ having a positive electric charge. Its mass is 1,836 times greater than an electron's mass and just a little bit less than that of a neutron (the proton–electron mass ratio). "Nucleons" refers to protons and neutrons together, each of which has a mass of roughly one atomic mass unit (particles present in atomic nuclei).

Each atom. has a nucleus. that contains one or more protons. In order to keep the atomic electrons bound, they offer the central attractive electrostatic force. An element's defining characteristic, known as the atomic number, is the number of protons in the nucleus (represented by the symbol Z)
