explain why hydrogen is arranged with group IA elements?
Answers
Answer:
Hydrogen is normally put in group 1 because it has 1 valence electron in the same way as group 1 metals. It can also be put at the top of group 17 (7a) because it needs 1 electron to fill its valence electron 'shell'
Explanation:
Hydrogen is a colorless, odorless and tasteless gas that is the most abundant element in the known universe. It is also the lightest (in terms of atomic mass) and the simplest, having only one proton and one electron (and no neutrons in its most common isotope). It is all around us. It is a component of water (H2O), fats, petroleum, table sugar (C6H12O6), ammonia (NH3), and hydrogen peroxide (H2O2)—things essential to life, as we know it.
