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.
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.
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.
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.
This single atom remain an atom of krypton !
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.
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 ion forms when an atom gains or loses electrons to have a stable electron configuration. When an atom gains electrons, it forms a negatively charged ion (anion), and when it loses electrons, it forms a positively charged ion (cation).
When an atom loses or gains electrons, it becomes an ion.
