The size of the atoms a and the number of holes in the atoms can be used to decode the element.
<h3>What are models?</h3>
A model is a miniature depiction of reality. Molecular models often consists of boxes that contain balls which are used to represent elements. In common parlance, the color is used to show the type of element.
Apart from the color, the size of the atoms a and the number of holes in the atoms can be used to decode the element.

Answer:- oxygen.
Explanations:- The electronic configuration is given and we are asked to figure out the electrically neutral atom that will have the electron configuration, 
.
The sum of electrons for this electron configuration is 8. If we look at the periodic table then 8 is the atomic number of oxygen.
So, the electrically neutral atom for the given electron configuration is oxygen.
Answer:
a. because it is an element
Explanation:
its pure because it only has one type of atom, making it an element
The answer is metal. Metals are always named first in ionic compounds, like KNO3 for example. I hope this helps!
