That depends on the number of protons and electrons present. One electron has a charge of minus one. A proton has a charge of plus one. Add charges to arrive at the charge of the atom total.
Example: an H+ ion consists of a single proton, and has no electrons. Its charge therefore is +1.
Hydrogen has a positive charge.
An atom with an electrical charge is called an ion.
When an atom has an electric charge it is called an ion.
When an atom has an electric charge it is called an ion.
An ion
A negative charge that exists because of a covalent bond with hydrogen
An atom that is not an ion has no electric charge. If it is particles that make up the atom you speak of, the nucleus houses the neutron; an elementary particle with zero charge.
Protons have a positive charge. Electrons have a negative charge.
An atom with an electric charge is called an ion. An ion is the result of an imbalance in the number of protons and electrons. If there is more protons than electrons then your atom will have a positive charge. If more electons then it will have a negative charge.
The neutrons are the part of the atom that carry no electric charge. They are found in the nucleus. the protons carry a positive charge and the electrons carry a negative charge.
Such an atom would be neutral - no electric charge.
In chemistry, particles with an overall electric charge are called ions.
