Ionic bond
There is one electron on cobalts outer shell.
4V V-Valence Electrons Valence Electrons-Last electron (which is on the outer shell)
The outer most electron shell of iodine atom contains 7 electrons.
no electron is present in the outer most shell of hydrogen ion
Valence Electrons
The outer shell (N=4) of the copper element has 2 electrons.
Alkali metals have 1 electron in their outer shell.
The outer shell is called the valence 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.
Nitrogen has 5 electrons in its outer shell, so there are 3 electron pairs in the outer shell of nitrogen.
These are the valence electrons.
