Valence electron varies according to the group the element is in.
Explanation:
For instance, hydrogen is in group 1. Hence, it has a valence electron of 1.
Carbon is in group 14. Hence, it has a valence electron of 4.
Xenon is in group 18. Hence, it has a valence electron of 8.
I am sure you see the pattern by now.
