when an element has 8 electron in outer shell it is said to be inert. inert gases are called noble gases.
Noble gases.
These are the valence electrons.
There is one electron on cobalts outer shell.
Electron outer shell tee hee =^-^=
You just said it, electrons. The "shell" is just an energy level. It is called a shell because it surrounds the atom, but it is just the electrons. Since there is no way to determine the exact location of an electron, it is referred to as an "electron cloud."
It will gain an electron so that it can complete a full outer shell of 8 electrons.
Valence Electrons
These are the valence electrons.
The outer shell is called the valence shell

Valence Electrons
There is one electron on cobalts outer shell.
4V V-Valence Electrons Valence Electrons-Last electron (which is on the outer shell)
Sodium is in the third group in the periodic table. It meens that sodium has three shell. First shell - 2 electrons, second shell - 8 electrons, third shell (outer energy level) - 1 electron.
The outer most electron shell of iodine atom contains 7 electrons.
Outer energy level electrons, or valence electron.
The electrons in the outermost shell is called as valence electron. These electrons are free and they are involved in bonding reactions.
manganese have 2 electrons in their outer most shell
