Sodium will electrons to go from neutral to Na+1. Sodium, Na, has (number) total electrons, while the sodium ion, Na+1, has (number) total electrons.

1. Lose

2. 11

3. 10

Explanation:

When an ion is formed it either loses or gains an electron in this case since the ion is positive it means it has lose an electron, since electrons provide a negative charge. So since it goes from Na to Na+1 it has lost an electron.

The number of electrons is based off of the number of protons/ the atomic number of the element. Sodiums atomic number is 1 1 and since it lost and electron it would go down to 10.

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.
