Answer:
<h3>
C. 3</h3>
Explanation:
there are three electrons in a 2p sub-energy level of s neutral nitrogen atom.
Magnesium (Mg) has atomic number 12 with electronic configuration :

The valence shell of Mg is 3s which has 2 electrons as shown in above electronic configuration.
Therefore, A = 3 and B =2
Answer:
A + B → C
Explanation:
Hello,
In this case, when talk about chemical reaction, in general terms they could be combination, decomposition, single displacement and double displacement, thus, combination chemical reactions are those reactions that have two reactants which combine to yield one single product.
In such a way, the reaction accomplishing the aforesaid description turns out:
A + B → C
Since A and B are the reactants and C the product resulting from the combination.
Best regards.
