If an atom donates or accepts an electron it is considered an ion.

When an electron is removed from an atom, it is considered to be ionized. This results in the formation of a positively charged ion known as a cation, while the atom itself becomes positively charged.
IF it donates an electron -then atom gains positive charge and if it accepts an electron then it acquires negative charge. the mass of an atom is dependent on protons and neutrons in the nucleus and electrons decide the charge of an atom
It accepts one electron.
The energy change that occurs when an atom gains electrons is called the
if a neutral atom donates an electron it will gain a positive charge. This is due to electrons having a negative charge.
An atom can become an ion by either gaining or losing electrons. If it gains electrons, it becomes an anion. If it loses electrons, it becomes a cation. An ion is merely an atom with a charge, either positive or negative.
They form an ionic bond
A substance that can donate a lone pair of electrons is called a Lewis base. The definition of a Lewis base is a compound or ionic species that can donate an electron pair to an acceptor compound.

An atom that accepts an electron is called reduced because it gains electrons, which leads to a reduction in its oxidation state. In a reduction-oxidation (redox) reaction, the atom that accepts electrons is undergoing reduction, not oxidation.
The atom that accepts electrons at the end of the electron transport chain is oxygen. Oxygen acts as the final electron acceptor in aerobic respiration, combining with electrons and protons to form water.
An ionic bond is formed between atoms when one atom donates an electron to another atom. Typically, this occurs between a metal atom, which easily donates electrons to form positive ions, and a nonmetal atom, which readily accepts electrons to form negative ions. Examples include the bond between sodium (Na) and chlorine (Cl) to form sodium chloride (NaCl).
The neutral atom then takes on a negative charge because the incoming electron has a negetive charge.
Actually, when sodium forms an ionic bond with chlorine, the sodium atom donates one electron to chlorine, resulting in the formation of a positive sodium ion and a negative chloride ion. The sodium ion becomes Na+ and the chloride ion becomes Cl-.
accepts an electron to become the chloride anion, Cl-
It depends on the exact situation. Probably ions Well this answer is vaguely correct. When an atom gains or loses an electron it becomes an ion. Ions with a net positive charge are called cations and ions with a net negative charge are anions. This allows for an ionic bond to occur. An ionic bond occurs when an anion binds with a cation.
