Answer:

3 electrons

Explanation:

The elements of group 5A of the periodic table are the following:

nitrogen, sodium, arsenic, antimony and bismuth.

To determine the amount of electrons in the last energy level we need to know the electronic configuration of each element.

Electronic configuration

N: [He] 2s2 2p3

P: 1s2 2s2 2p6 3s2 3p3

As: [Ar] 3d10 4s2 4p3

Sb: [Kr] 4d10 5s2 5p3

Bi: [Xe] 4f14 5d10 6s2 6p3

As we can see they all have 3 electrons in their last energy level .

What specifically determines how much energy is available in a molecular

HACTEHA [7]

C The number and types of bonds within the molecule.

Explanation:

In a molecule, the number and types of bonds present determines the amount of available energy therein.

When bonds are broken or formed, energy is usually released.

Elements combine with one another in order to attain stability in this state.
Through this process, they form bonds by attraction.
Where atoms exchange their valence electrons by losing or gaining it, electrovalent bonds form.
In covalent molecules, electrons are usually shared between atoms.
An attraction result from this type of interaction.
The bond formed stores energy in the process.
When bonds are broken, energy is usually released. The energy accrues when the bond was being formed.
In molecules, we have covalent bond.
