Oxygen is in group 16 so it has 6 valence electrons. In order to have a full outer shell, and satisfy the octet rule, it needs 2 more valence electrons to have a full outer shell.
It already has 6 and it needs 8. So, it need 2 more.
Oxygen has a total of 6 valence electrons; 2 in the 2s sublevel and 4 in the 2p sublevel. It needs two additional 2p electrons to fill its octet.
Oxygen has 2 valence electrons.
6 valence electrons 1s2 2s2 2p4 These 6 valence electrons are in the outer shell.
The outer shell is called the valence shell
outer shell electrons are knows as Valence Electrons
Valence Electrons
4V V-Valence Electrons Valence Electrons-Last electron (which is on the outer shell)
In the first shell there are two electrons and in the second shell there are six electrons, but only the electrons in the second (outer) shell are valence electrons.
Elements in the same group have the same number of valence electrons. These are the outer-shell electrons that react with other elements.
The valence electrons
The valence shell is the outer most shell or imaginary orbit of an atom containing <8 electrons. The electrons in this shell are called 'valence electrons'.
The valence shell is the outer most shell or imaginary orbit of an atom containing <8 electrons. The electrons in this shell are called 'valence electrons'.
valence electrons are the electrons on the outer-most shell of electrons
