If you're asking how will an atom with 5 valence electrons will achieve a full set of valence electrons, then the answer would be that they bond with other atoms to gain a full set of the valence electrons by sharing or gaining 3 electrons.
The octet rule.
A full set of valence electrons typically consists of 8 electrons, except for hydrogen and helium, which have a full valence shell with 2 electrons.
An atom with 5 valence electrons can achieve a full set of 8 valence electrons by either gaining 3 electrons through bonding with other atoms or losing 5 electrons by forming ionic bonds. Another option is to share electrons with other atoms through covalent bonding to reach a stable octet.
An atom with five valence electrons can achieve a full set of eight valence electrons by either gaining three electrons (to reach a stable octet) or losing three electrons to have a stable arrangement. This would result in the atom forming an ionic bond, such as in the case of boron transferring three electrons to become the boride ion.
Phosphorus, with 5 valence electrons, needs to gain 3 electrons to have a full set of 8 valence electrons. This would allow it to achieve a stable octet configuration, resembling the noble gas configuration of argon.
An atom with 4 valence electrons will have to either gain 4 electrons or lose 4 electrons to achieve a full set of eight electrons.
They will gain 3 electrons from something with 3 valence electrons.
The octet rule.
An element that does not require eight electrons for a full set of valence electrons is represented by the element symbol B. Boron only needs six electrons to complete its valence shell and achieve stability.

It does.
This is called an "octet" of electrons. It could also be called a "closed shell", since it is characteristic of the outer shell of noble gas atoms.
Neon has 8 valence electrons. This is because neon is in the 8th group (or 18th column) of the periodic table, and elements in this group have a full set of 8 valence electrons.
They all have a full set of valence electrons.
