Explanation:

• Alkaline earth metals have 2 valence electrons.
• Boron group has 3 valence electrons.
• Nitrogen group has 5 valence electrons.
• Halogens (Group 17) have 7 valence electrons.
• Noble gases (except helium) have 8 valence electrons.
• Alkali metals have 1 valence electron.
• Lanthanides and Actinides are f - block elements with complex electron configurations not relevant here.
• Transition metals have variable valence electrons.
• Oxygen group has 6 valence electrons.
• Carbon group has 4 valence electrons.

Answer:

Halogens
