it was to gain 3 more valence electrons so it can be like the noble gases.
Ionic type of bonding is highly favored among the ionic species, where one atom has tendency to donate electrons and the other has tendency to accept electrons in order to attain a stable atomic coniguration with a filled outer shell of electrons.
The valance electrons. The outer level of electrons every atom has. Every atom has a full valance shell at 8, so only the Nobel gasses are nonreactive naturally and other atoms either donate or accept the number of electrons needed to come to an octet of electrons.
Eight - it has a full outer shell of electrons.
This atom could be any of a number of different elements: having 8 valance electrons does not necessarily mean that the outer shell of the atom is full as larger atoms can store more electrons per shell (first shell=2, 2nd=8, 3rd, 18, etc)
There are three valance electrons. These are the electrons in the outer shell if it is not full.
Not really. Argon is a Nobel gas with a full valance octet; 8 valance electrons that do not need to accept or donate electrons to be '' happy. ''
A full octet, valance shell. A valance shell with eight electrons, such as the Nobel gases have, doe not need to donate or accept electrons into or out of the valance shell to be stable.
Classic answer is to "satisfy" a full valance ring of electrons.
The second energy level contains eight valance electrons when it's full.
Because , It's Outer Shell Is Totally Full With 8 Electrons .
If K and L shell are full then the number of electrons in that atom is 10.
