Atomic Number definition: The number of protons within the nucleus of x atom.
Atomic Mass definition: The number of protons and/+ neutrons within the nucleus of x atom.
The given information states that the element has 8 protons and 8 neutrons in its nuclei with 8 electrons revolving around it. If the atomic number is 'the number of protons' and we have 8 given protons, our answer would be 8. If the atomic mass is protons + neutrons and we have 8 protons and neutrons, our answer for atomic mass would inevitably be 16.
Therefore
Atomic number: 8
Atomic mass: 16
Earth's atmosphere is 78% nitrogen, 21% oxygen, 0.9% argon, and 0.03% carbon dioxide with very small percentages of other elements. Our atmosphere also contains water vapor. In addition, Earth's atmosphere contains traces of dust particles, pollen, plant grains and other solid particles.

Explanation:
The salt and water are a homogeneous mixture but when salt dissolves in the water system is called a solution of salt and water.
<h3>What is a mixture? </h3>
A mixture is defined as the combination of two or more substances that are not chemically bonded together.
There are two types of mixture which include:
- Homogeneous (uniform composition) and
When salt is added to the ice water system, it lowers the freezing point of the ice water thereby forming a homogenous mixture of water and salt.
The dissolution of salt in ice water leads to the formation of salt and water solution.

The result of Moseley's revisions were that the elements were arranged in atomic number order rather than atomic mass order.
