Draw a Lewis dot diagram for NF2H and use the oxidation state method of electron bookkeeping to determine how many electrons each atom should be â¦ See the answer. Chlorine is a yellow-green gas at room temperature. Now for #Cl_2#, the symbol means that there are two #Cl# atoms sharing electrons to form a substance, which is the chlorine gas. Half reactions for this redox reaction are: Cl2 + 2e- ---> 2Cl- Eo = +1.36 V  Cl (0) ---> Cl (-1) Reduction: gain of â¦ This problem has been solved! > We can use the rules for oxidation numbers. Show transcribed image text. Hence, [x + (0 X 2) + ( -1 X 2)] = 0 x + 0 -2 = 0 x = 2. +1.

For an ion, the oxidation state is the charge. Since one chloride ion has a charge of -1, then that would be its oxidation state. ; When oxygen is part of a peroxide, its oxidation number is -1. Thus we can calculate the formal charge as: #Cl# atom: 7 valence electrons; therefore, total valence electrons is 14. as we know oxidation state of oxygen is -2 therefore the equation can be 2x+(-2)=0 where x is the oxidation state of chlorine ..now on solving we get answer as 1. In case of [Ni(NH3)6]Cl2 complex, the oxidation state of nickel atom is +2 .The atomic number of nickel atom, 28 and that of Ni(II)ion is 26 ..
