The chemical symbols are the letters used to denote the periodic element. Some of them are Lithium (Li), Bromine (Br), Iron (Fe), Oxygen (O), Copper (Cu), Mercury (Hg), Helium (He), and Arsenic (As).
What are protons?
The subatomic particle present in the nucleus along with the neutrons held by the strong nuclear force is called a proton. The number of protons determines the atomic number and the characteristic of the element.
The chemical symbols and proton number of the following elements are:
- Lithium: Li - 3
- Bromine: Br - 35
- Iron: Fe - 26
- Oxygen: O - 8
- Copper: Cu - 29
- Mercury: Hg - 80
- Helium: He - 2
- Arsenic: As - 33
The number of protons of the elements is equivalent to the atomic number.
Therefore, the protons determine the physical and chemical properties of the element.
