Question
Oxygen has 6 valence electrons.
Calculate the number of electrons it will share in a covalent bond to get a full outer shell.
Solution
Oxygen, being in Group 16 of the periodic table, has 6 valence electrons. To achieve a full outer shell, it needs 8 electrons. This is based on the octet rule, which states that atoms are most stable when their outermost shell is full, typically with 8 electrons.
So, to calculate the number of electrons oxygen will share in a covalent bond to get a full outer shell, subtract the number of valence electrons oxygen already has from the total needed for a full shell.
8 (needed for full shell) - 6 (oxygen's valence electrons) = 2
Therefore, oxygen will share 2 electrons in a covalent bond to achieve a full outer shell.
