This is sometimes known as group of chalcogens (due to ore forming nature). Atomic configurations ns2np3! 8. Group 15 elements have higher ionization energy than group 16 elements because they have stable electronic configuration i.e., half-filled p-orbitals. (b) This is because halogens are reactive non-metals. All of these are gases and chemically unreactive. The electronic design of helium is 1s2. [2] K atoms have one more electron shell than Na atoms. 18.7 GROUP-17 ELEMENTS-THE HALOGEN FAMILY. The initial four elements of the group are together termed as chalcogens or ore-forming elements.
