Hydrogen atomic number 1 , electronic configuration is the first element in the periodic table. It resembles alkali metals as well as halogens.
Hence, its position is anomalous. Some chemists argue that hydrogen should be placed along with alkali metals whereas other chemist argue that hydrogen should be placed with halogens.
Final answer:
Hydrogen with atomic number 1 and electronic configuration is the first element in the periodic table. It resembles alkali metals as well as halogens. Hence, its position is anomalous. Some chemists argue that hydrogen should be placed along with alkali metals whereas other chemist argue that hydrogen should be placed with halogens.
