electron dot structure
Explanation:
Chemical reactions are driven by transfer or sharing of electrons between two or more atoms. To show a specie that is reactive, a sound knowledge of the distribution of electrons in the atom is necessary.
- The electron dot structure shows only chemical symbol of the element surrounded by dots which represents the valence electrons.
- The chemical symbol represents the nucleus and all electrons except the valence ones.
- The dots arranged on the four sides are called lone pairs. Those that are unpaired are called odd electrons.
- Chlorine has 7 valence electrons in its outermost shell.
- It is made up of 3 lone pairs and 1 odd pair of electron.
- The odd pair accounts for the reason why chlorine is very reactive.
- It will only require just one electron to join the odd pair so as to complete the octet and be like the noble gases.

Answer:
Explanation:
N₂ (g ) + 4H⁺( aq ) + 4e⁻ = N₂H₄ ( aq )
H⁺ ion comes from acidic medium . 4 positive charge on proton is balanced by 4 electron to make left hand side neutral because right hand side is neutral .
I'm not sure, but I believe the correct answer is C.
