It is ionic bond because of Na valency and it is alkali metal and cl is non metal and it’s valency , they both share electron and make ionic bonding .
Proton plus neutron is the correct answer. Protons and neutrons have a mass of 1 and electrons have a mass of 0. So in order to find the mass of an atom you need to add the number of protons and the number of neutrons.
Answer:
2NO + 4H-> N2 + 2 H2O
Explanation:
Both sides must be equal. :)
Since I don't have the diagram I'm going off my best estimate and the flow of the positive and negative charged protons and neutrons create a flow of energy when collided through a circuit or in this case the wire
