The contact with an atom having a high affinity for electrons.
lose one or more electrons.
It must lose two electrons.
Two.
It would have to lose two electrons.
Valency refers to the number of electrons an atom needs to gain or lose to achieve a stable electron configuration. Atoms generally tend to gain, lose, or share electrons in order to attain a full outer shell of electrons, following the octet rule. This helps the atom achieve a more stable and lower energy state.
Calcium will lose two electrons to gain the noble gas configuration of Argon.
A full outer electron shell. Atoms tend to be more stable when they have a full valence shell, which typically contains eight electrons. This stability makes it less likely for the atom to either lose or gain electrons.
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).
An atom can lose electrons to other atoms during a chemical reaction. This process results in the atom becoming positively charged, forming an ion.
Ionic bonds are formed when atoms lose or gain electrons in order to have a full outer shell of electrons to make them stable.One atom pulls an electron from another atom.

The gain and/or lose of electrons.
