Answer is: carbon.
<span>During gamma emission the nucleus emits radiation without
changing its composition, if for example have nucleus with six
protons and six neutrons (carbon atom) and after gamma decay there
is nucleus with six protons and six neutrons.
Gamma rays are the electromagnetic waves with
the shortest wavelengths (1 pm), highest frequencies (300 EHz) and
highest energy (1,24 MeV).</span>

Answer : The balanced chemical equation is,

Explanation :
Rules for the balanced chemical equation in basic solution are :
- First we have to write into the two half-reactions.
- Now balance the main atoms in the reaction.
- Now balance the hydrogen and oxygen atoms on both the sides of the reaction.
- If the oxygen atoms are not balanced on both the sides then adding water molecules at that side where the more number of oxygen are present.
- If the hydrogen atoms are not balanced on both the sides then adding hydroxide ion
at that side where the less number of hydrogen are present. - Now balance the charge.
The half reactions in the basic solution are :
Reduction :
......(1)
Oxidation :
.......(2)
Now multiply the equation (1) by 2 and then added both equation, we get the balanced redox reaction.
The balanced chemical equation in a basic solution will be,

I believe the answer is C
Answer:
-2
Explanation:
7 x 1 - 2 x 1 + 1 x 1 + 3C = 0 (no charge)
6 + 3C = 0
C = -2
