PLEASE HELP This picture represents a model of:

Question 5 options:

Oxygen

Calcium

Boron

Neon

The picture represents oxygen.

Explanation:

There are two notable ways you can figure this out:

1) Since there are eight protons, you can automatically know that you are looking for an element with an atomic number of 8. This is because the atomic number is the number of protons in an atom.

2) You can also note the number of electrons on the outer shell. These are called valence electrons. You can then see that the element has 6 valence electrons. Beginning with Lithium on the periodic table and count by ones going from left to right in period 2 of the periodic table until you get to 6. What element is that? It is indeed oxygen.

Oxygen

Explanation:

Neons contain 8 protons and 10 ELECTRONS

Boron contains 5 protons an 5 electrons

calcium contains 20 electrons an 0 protons

let that person have a turn to speak : )
