The atomic number of an element
wlad13 [49]

According to the research, the correct answer is that the atomic number of an element is usually denoted by the letter Z and represents the stable compound particles of a positive elementary charge.

<h3>What is the atomic number ?</h3>

It is a total number of the smallest particles that make up the atom with a positive electric charge that is denoted with the letter "Z" that make up the atomic nucleus of a certain chemical element.

In this sense, each chemical element has a different atomic number, although its chemical way of behaving is established by the electrons that orbit around its nucleus.

Therefore, we can conclude that according to the research, the atomic number presents the different amounts of protons in the atoms of different elements.
