it becomes an ion
Ion
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.
If an atom gains or loses electrons, it becomes an ion. If it gains electrons, it becomes a negatively charged ion called an anion. If it loses electrons, it becomes a positively charged ion called a cation.
This neutral atom become a cation or an anion.
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 .
They are known as ions.
An atom becomes charged when it gains or loses electrons to form an octet.
When an atom gains electrons, negatively charged anions are formed. When an atom loses electrons, positively charged cations are formed.
Cations are positive ions, so an atom is supposed to lose electrons to become a cation. Anions are formed when an atom gains 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
An ions is formed when an atom gains or loses electrons.
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.
