Question

Give the periodic group number and number of valence electrons for each of the following atoms: a) Ob) Bc) Nad) Mge) Ff) S

Answer 1

The valence electrons of oxygen are 6

Step-by-step 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
