Question

why hydrogen is in group 1 not in group 17 having similar properties?

Answer 1

Dear student,

Hydrogen has electronic setup of 1s1. It can acknowledge the electron from metals to satisfy its external orbital like gathering 17 components. Then again, it can give its electron to shape H+ particle which is the attributes of the gathering 1 components.

Likewise, it has an electronic design like gathering 1 components. Then again, it takes after gathering 17 components as it shows higher ionization enthalpy like incandescent light.

Along these lines, hydrogen looks like both gathering 1 and gathering 17 components
