the elements having full valence shell donot react as they are inert in nature.
No, only the noble gases in the far right column have a full valence shell.
None. Neon is a noble gas, a category of elements that exist in nature as inert gasses. In special situations, neon can be made to react with other elements, but in ordinary conditions, neon is inert, which just means non-reactive. It's outer orbit is full--it doesn't want to give up the electrons it has, or to take any more.
it needs six more electrons to have a full outer valence shell.
If magnesium (Mg) has a full valence shell, it would have a 2+ charge. This is because magnesium has 2 valence electrons and would need to lose these electrons to achieve a full valence shell, resulting in a 2+ charge.
the electrons on their outer shell, all atoms want to gain a full valence shell.
No, sulfur does not have a full valence shell. It has six valence electrons and needs two more to achieve a full octet, which consists of eight electrons. In chemical reactions, sulfur typically forms compounds by gaining, losing, or sharing electrons to complete its valence shell.
Sodium does not have a full outer valence shell. It has one electron in its outermost shell, which makes it very reactive and likely to lose that electron to achieve stability.
Krypton is a noble gas and hence has stable electronic configuration. Its valence shell configuration is 4s2 4p6 . Therefore, it has 1-s and 3-p full orbitals in its valence shell.
All eight: the shell is full.
Oxygen needs 2 more valence electrons to have a full outer shell. Oxygen has 6 valence electrons, and a full outer shell for oxygen is achieved at 8 valence electrons.
Electron outer shell tee hee =^-^=
A fluorine atom can accommodate one more electron in its valence shell to achieve a full valence shell of 8 electrons.
