It depends on the charge on the atom at the start before it gains an electron. The electron has a charge of -1, and will make an atom more negative or less positive (both of which are the same thing). Let's look at the possibilities. If an atom is neutral (zero net charge) and gains an electron, it has a net charge of -1. If an atom is at +1 and gains an electron, it has a net charge of zero. If an atom has any positive charge, p, above +1, it has a net charge of p - 1. (A +5 would become a +4, and a +3 would become a +2.) If an atom has any negative charge, n, then its net charge becomes n - 1. (A -4 would become a -5, and a -2 would become a -3.)
The charge of a sodium ion when it loses 1 electron is +1. Sodium is a group 1 element, so it has 1 electron in its outer shell. When it loses this electron, it becomes a positively charged ion with a charge of +1.
An ionic bond is formed between a metal and a non metal. The METAL loses an electron (or electrons) and it becomes positively charged.
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.
If an atom loses 3 electrons, it gets a charge of +3. (One positive charge for every electron lost). If an atom loses 2 electrons, it gets a charge of +2.
When potassium loses an electron, it forms a cation with a charge of +1. The formula of the ion formed when potassium loses an electron is K+.
The charge of a sodium ion when it loses 1 electron is +1. Sodium is a group 1 element, so it has 1 electron in its outer shell. When it loses this electron, it becomes a positively charged ion with a charge of +1.
When "x" valence electrons are lost the charge is +x When "x" valence electrons are gained the charge is -x for example, if chlorine gained one electron, the charge would be Cl 1- or, if magnesium lost two electrons, the charge would be Mg 2+

When an atom loses an electron it becomes a positively charged ion.

When potassium loses an electron, it forms a cation with a charge of +1. The formula of the ion formed when potassium loses an electron is K+.
If it loses an electron (negative charge) it becomes positive.

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.
The element hydrogen forms an ion with the same charge as the ammonium ion, which is +1. When hydrogen loses an electron, it becomes a hydrogen ion with a +1 charge, just like the ammonium ion.
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.
