ANSWER
The valence electrons of oxygen are 6
EXPLANATION
The first element is OxygeN
Oxygen has an atomic of 8
This implies the number of electrons is 8
Recall, that the valence electron is the combining power of an element. Hence, the valence electron is always the number of electrons at the outermost shell of the element
Oxygen = 2, 6
The next step is to draw the atomic structure of the oxygen atom
From the structure above, you will see that there are 6 electrons in the outermost shell of the oxygen atom.
Hence, the valence electrons of oxygen are 6
