Electrons have a positive charge and protons have a negative charge. An atom's nucleus is 99.95% of its weight. When an object gains more electrons, it gains a negative charge that over comes the positive charge. This only happens when there are more electrons than protons.

A material has a net charge because it?
A net charge results when an atom gains or loses electrons. If it loses electrons, it gains a positive charge, if it gains them, it gains a net negative charge.
What happens when an element gains electrons?
If a neutral atom gains one or more electrons, then it will have a negative change. If a positive atom gains electrons, it will have an increase in change, but the charge may be negative, neutral, or positive based on the initial charge and number of electrons gained. The process in which an atom gains electrons is known as reduction.
What is the energy change that occurs when an atom gains electrons called?
The energy change that occurs when an atom gains electrons is called the
When an atom gains an electron what charge does it have?
An atom that gains three electrons will become an ion with a 3- charge.
When the number of electrons in an atom changes what is the new atom called?
When an atom loses or gains electrons, it becomes an ion.
What do you call an atom that gains or loses electrons?
An atom that gains or loses electrons is called an ion. If it gains electrons, it results in a negative ion called an anion. If it loses electrons, it results in a positive ion called a cation.
A material has a net charge because it?
A net charge results when an atom gains or loses electrons. If it loses electrons, it gains a positive charge, if it gains them, it gains a net negative charge.
What does an atom become if it gains or loses electrons?
An ION. Ions are divided into two classes. CATIONS ;positive ions e.g. Na^(+) ANIONS ; negative ions e.g Cl^(-)

When a neutral atom gains electrons it is then?
This atom become an anion.

An atom that gains three electrons will become an ion with a 3- charge.
When the number of electrons in an atom changes what is the new atom called?
When an atom loses or gains electrons, it becomes an ion.
What is an atom that gains and loses an electron and has an electric charge?
When an atom gains electrons, negatively charged anions are formed. When an atom loses electrons, positively charged cations are formed.
What do you call an atom When an atom losses or gains electrons its called an?
cell
A strontium atom differs from a stontiun ion in that the atom has a greater what?
electrons. Ions exist when an atom gains or loses electrons
What is the bond which results from the transfer of electrons from one atom to another?
An ionic bond results from the transfer of electrons from one atom to another. The atom that loses electrons becomes a positively charged ion, or cation. The atom that gains electrons becomes a negatively charged ion, or anion. The ionic bond that forms between them is the electrostatic attraction between the oppositely charged ions.
