Question

What is atomic number?​

Answer 1

the number of protons in the nucleus of an atom, which is characteristic of a chemical element and determines its place in the periodic table.

Answer 2

Explanation:

Atomic number refers to the amount of Protons present in an element. Since all atoms are neutrally charged, it means that there are equal Protons and Electrons in an atom.

So, atomic number is the number of Protons, which is always equal to the number of Electrons too. For example:

• Helium (He) has the atomic number two. This means that it has two Protons, and since Protons are always equal to the number of Electrons, it has two Electrons too. Simple!

I hope this helps!!
