The number of electrons in the outermost shell of an atom determines its reactivity. EX: noble gases have a low reactivity because they have a full electron shell, and don't need any more outermost ones.
EX: halogens are highly reactive because they readily gain an electron to fill their outermost shell
Answer:
magnesium chloride
Explanation:
Complete step-by-step answer:
The remaining ions combine to produce the salt of neutralisation. The salt is magnesium chloride. The chemical formula for the compound is $MgC{{l}_{2}}$.
The given gives an equation <span>4NH➡ 2N² + 6H². The equation given is not correct since H is not balanced. on the right side,H is counted as only 4 while on the right side, H is 12. The compound on the right should be ammonia, NH3 in order to balance the equation.</span>
