Assuming the atoms starts off as a neutral atom, the new charge will be:0 - (-1) = +1
When an atom loses an electron it becomes a positively charged ion.
If it loses an electron (negative charge) it becomes positive.
An electron has a charge of -1. When a Sodium (Na) atom loses one electron, it loses a negative and becomes a stable Sodium ion with a charge of +1.
When an atom loses an electron, it becomes a cation and has a positive charge.
When an atom/molecule loses an electron, it is oxidized. The particle develops a positive charge, and thus becomes attractive to particles which have an opposite (negative) charge.
A neutral atom that subsequently gains or loses one [or more] electrons is called an ion. If it gains an electron [or electrons] it will have a negative charge. If it loses an electron [or electrons] it will have a positive charge.
When an atom loses electrons it becomes ionized and more positive a charge. Losing an electron can cause this atom to react with other atoms.

An electron has a negative charge. If an atom loses an electron it creates an ion with a positive charge. If an atom gains an electron it creates an ion with a negative charge.
An atom becomes more positive when it loses an electron because electrons carry a negative charge. When an atom gains an electron, the atom becomes more negative.
Gain of an electron transform the atom in an anion.Loss of an electron transform the atom in a cation.
The Sodium atom with be positively charged [it will have a single positive charge]
