When an atom gains or loses electrons, it gains a negative or positive charge respectively. Atoms generally try to gain enough electrons to fill their outer, valence electron shell. For the first shell the number of electrons is 2 and for all others, atoms usually want 8 electrons.

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 an atom combines chemically with another atom it either gains loses or share what?
It either gains, loses, or shares electrons.
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.
When a atom gains or loses electrons it becomes what?

When a atom loses or gains electrons it becomes an?
Ion
An ion is formed when am atom?
An ions is formed when an atom gains or loses electrons.
When are ions formed?
Ions are formed when an atom gains or loses electrons. When an atom loses electrons the Ion that is formed has a positive charge.
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.
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 forms when atom gains or loses electrons?
An ionic bond.
When an atom gains or loses one or more electrons?
Isotope
