They have one valence electron. If this electron is lost, the atoms form cations with the electronic configuration of the nearest noble gas.
Atoms gain, lose or share electrons and try to attain noble gas configuration.
Atoms gain stable configuration of noble gas, by either gaining or losing (as in ionic compounds) or sharing electrons (as in covalent compounds).
No Such ... all atoms have an electron configuration, yet Ca++ is not a noble gas.
Hydrogen gas has the noble gas electron configuration with a single covalent bond; it only requires two electrons for this (you've probably heard the "duet rule"). Otherwise, in the right conditions, you can maybe combine two atoms in the 4A group (Carbon, Silicon, Germanium, Tin, Lead, etc.), or an atom in the 3A plus an atom in the 5A group. All other combinations would be considered ionic bonds.
nitrogen will get noble gas configuration by adding three more electrons.
Atoms gain, lose or share electrons and try to attain noble gas configuration.
Atoms lose or gain or share electrons and tend to attain noble gas configuration
Atoms gain stable configuration of noble gas, by either gaining or losing (as in ionic compounds) or sharing electrons (as in covalent compounds).
By acquiring noble gas configuration elements become stable .
They should gain 2 electrons to attain noble gas electronic configuration. (it doesn't become a noble gas as the number of protons are not same)
Only group 18 elements have noble gas configuration. All other elements lack a noble gas electronic configuration.
The atoms of the molecule effectively achieve a noble gas configuration by sharing valence electrons.
Metals like sodium,potassium get noble gas configuration by losing electrons. Elements like nitrogen,oxygen get noble gas configuration by gaining electrons. Halogens get noble gas configuration by sharing electrons.
