Electrons have a -1 charge while protons have a +1 charge. Thus, subtracting the number of electrons from the number of protons gives the charge of a species. For example, if a lithium ion has 3 protons and 2 electrons, it has a +1 charge.

Where would find electrons and what charge do they have?

Electrons are found outside the nucleus of the atom and they have negative charge.


How can you find he number of electrons in an atom?

in an atom of neutral charge, the number of electrons will be the same as the number of protons, or the atomic number.


What is the charge of the particles you find outside of an atom's nucleus?

Those are electrons, and they have a charge of minus 1.


What particles around the atom have negative charge?

only the electrons have a negative charge but they go around the nucleus


How do you find the overall of an atom?

(Atomic number) - (Number of electrons present) = (overall electrical charge of atom)


How do you find how many electrons an atom has?

Knowing which element it is and its formal charge, subtract the charge from its atomic number.


Which particles affect the charge of an atom or ion?

The particles that affect the charge of an atom or ion are electrons and protons. Electrons have a negative charge and protons have a positive charge. The number of electrons and protons in an atom or ion determines its overall charge.


What atom has 7 electrons and no charge?

A neutral nitrogen atom has 7 protons and 7 electrons, and has no charge.


What subatomic particles determine the charge of an atom?

Protons (+1 charge) and electrons (-1 charge) are the subatomic particles that determine the charge of an atom. Protons carry a positive charge, while electrons carry a negative charge. The number of protons in an atom determines its overall positive charge, while the number of electrons determines its overall negative charge.


When an atom has one or more extra electrons it will have a positive charge?

No. Electrons possess a negative charge, therefore an atom with an excess of electrons will have an overall negative charge.


What do electrons do in an atom?

They affect the charge of the atom.


Is an atom that loses electrons have a negative charge?

No. Electrons have a negative charge and so removing one from the atom will give it a positive charge.
