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

The atom is then considered an ion :)
It accepts one electron.
By bonding with another atom, either ionically (donates/receives electrons) or covalently (electron sharing).
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.
No! A sodium atom is initially electrically neutral. When it donates one electron to a chlorine atom, the sodium atom becomes a singly charged cation.

The very electronegative oxygen atom.
The neutral atom then takes on a negative charge because the incoming electron has a negetive charge.
The atom is then considered an ion :)
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.
accepts an electron to become the chloride anion, Cl-
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.
It needs just one electron to acquire a complete and stable outer shell.
