What do you notice in the number of valence electrons of metals,non-metals,and noble gases/
- Metals have fewer electrons of valence than non-metals and all noble gases have 8 electrons with the exception of helium.
- Valence electrons of metallic elements depend on their group number and have less valence electron than non-metals.
- Non-metal valence electron depends on their group number minus 10: for example, carbon belongs to Group 14, so that carbon has 4 valence electrons and more valence electrons than metals.
The no. of metals is increasing
The no. of non metals is decreasing
Noble gasses have 8 valence electrons and are stable.
