Question

give a general group study of hydrogen with reference to valance electrons, burning and reducing power

Answer 1

hydrogen
atomic number -1
number of electrons -1
number of protons -1
valancy - 1
being electronegative ( electron deficient ) it is a good reducing agent. it forms dihydrogen oxide also know as water
hydrogen burns with a pop sound.
hope it helps

Answer 2

here is your answer...

valence electrons:

Hydrogen has only 1 valence electron in its valence shell.

Burning:

Hydrogen burns in oxygen to form its oxide(water). Hydrogen burns with a pop sound.

Reducing power:

Hydrogen having valence electron 1, act as a reducing agent.
