An ion.
Loses two electrons.
An atom that loses one or more electrons is an ion, specifically a cation.
Ions are formed when an atom gains or loses electrons. When an atom loses electrons the Ion that is formed has a positive charge.
An ions is formed when an atom gains or loses electrons.
First of all to correct your English grammar. The question should read ; - " What is a**n** atom that g(r)ain or loses electrons?" The answer is an ION . A positively (+) charged ion is named a CATION A negatively (-) charged ion is named an ANION
When an atom loses or gains electrons, it becomes an ion.
This single atom remain an atom of krypton !
When an atom gains electrons, negatively charged anions are formed. When an atom loses electrons, positively charged cations are formed.
An atom that loses electrons becomes a positively charged ion called a cation. An atom that gains electrons becomes a negatively charged ion called an anion.
ION A positively (+) charged ion is named a CATION A negatively (-) charged ion is named an ANION NB When an atom becomes a charged species it is no longer an atom, but an ION . An atom has a neutral charge.
Cations are positive ions, so an atom is supposed to lose electrons to become a cation. Anions are formed when an atom gains electrons.
A neutral atom that gains or loses electrons is now an ION. If it loses electrons to become M^(n+), then it is a CATION. If it gains electrons to become X^(n-), then it is an ANION. NB Atoms that gain or lose electrons are no longer atoms , but IONS.
