How do i know a valence electron of any atom
Accepted Answer
The valence electrons of an atom are the electrons in the outermost electron shell. The number of valence electrons determines the chemical properties of an element. To find the valence electrons of an atom, you can look at the periodic table. The group number of an element is equal to the number of valence electrons. For example, oxygen is in group 6, so it has 6 valence electrons.
