Answer to Question #67604 in General Chemistry for Jess

Question

1. Why is hydrogen in group 1? Also refer to the electron configuration, the state of matter, the type of bonds and reactivity of hydrogen and also that of the elements in group 1.

2. Why can hydrogen be in group 17? Also refer to the electron configuration, the state of matter, the type of bonds and reactivity of hydrogen and also that of the elements in group 17.

Answer 1

The hydrogen is in the first group because the structure of the electron shell of a single energy source is indentic with the structure of the last level of alkali metals nS¹
Hydrogen has one unpaired electron as halogens and is capable of forming a diatomic gas because it is similar to halogens and can be in group 4
