An ionic bond.
For an atom to form an ion, it has to either gain or lose one or more electrons. Usually this happens during a chemical reaction, when an element gains or loses electrons to achieve noble gas configuration.
An ION . Metal (M) ionises ( loses electrons) M(g) = M^(n-) + ne^(-) M^(n+) is a CATION . Non-metal (X) has electron affinity ( gains electrons) X(g) + ne^(-) = X^(n-) X^(n-) is an ANION .
When an atom gains electrons, negatively charged anions are formed. When an atom loses electrons, positively charged cations are formed.
An ion.If the atom loses electrons it becomes a positive ion, a cation.If the atom gains electrons it becomes a negative ion, an anion.
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
An ions is formed when an atom gains or loses electrons.

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.
This single atom remain an atom of krypton !
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.
Yes, when electrons move from one atom to another, it can result in the formation of ions. If an atom gains electrons, it becomes negatively charged and forms an anion, while if it loses electrons, it becomes positively charged and forms a cation.
