The charge on an atom depends upon its electronegativity(the tendency of an atom to atract the shared paired of eletron),
Therefore the more the atom is electronegative the more it is capable of having negatively charge.
In Periodic Table,from top to bottom it decreases due to increase in the number of shell.
while from left to right it increases (some exception) due to increase in number of electron.
Fluorine is the most electronegative element(E.N=4)

The neutrons do not affect the charge of an atom. The positive charge is on the proton the equal but negative charge is on the electron.If an atom has more electrons than protons it will have an overall negative charge.
The charge of an atom is neutral overall, meaning it has an equal number of protons (positively charged) and electrons (negatively charged). If an atom gains or loses electrons, it becomes an ion with a positive or negative charge.
An atom with a charge (either positive or negative) is called an "ion." An ion with a positive charge is called a "cation" and an ion with a negative charge is called an "anion ."
Since protons have a positive charge and electrons have a negative charge, an atom with more protons than electrons would have a positive charge. Note that an atom with this kind of imbalance is known as an ion.
If an atom has 3 positive charges (protons) and 4 negative charges (electrons), the 3 positive charges would "cancel out" 3 negative charges, with one negative charge left over. So the atom would have a charge of -1.

A charged atom is called an ion.If it has more protons then electrons, it has a positive charge.If it has more electrons than protons, it has a negative charge.
An atom with positive charge is cation.An atom with negative charge is anion.
The atom may gain or lose an electron either making it positive or negative.
An ion is an atom of any element that either has a positive or negative charge.
Atoms are neutral. Ions can be charged, either positive or negative.
The charge of a nucleus is positive, as it contains protons which have a positive charge. The charge of an atom overall is neutral, as the number of protons (positive charge) is equal to the number of electrons (negative charge) in a neutral atom.
An ion is an atom with a positive or negative charge.
Positive charge: cationNegative charge: anion
Negative: The negative part of an atom is the electrons which have a negative charge and orbit around the nucleus. Positive: The positive part of an atom is the nucleus which contains protons with a positive charge.
Positive
electrons = negative charge protons = positive charge neutrons = neutral charge
