Question

How can we find the number of protons and electrons of any element?

Answer 1

The number of electrons and the number of protons of an chemical element is obtained with the help of a periodic table where the chemical elements are arranged. One should have the knowledge of periodic tables. The atomic number of the element represents the number of electrons present in it.

Complete step by step answer:
Atom is considered as the smallest unit of matter. Two or more than two atoms combine with each other to form molecules. After the atomic theory, it was discovered that the atom is composed of three different particles: electrons, protons and neutrons. The electrons are the negatively charged particles, protons are the positively charged particles and neutrons are the neutral charged particles. The atom has a center known as nucleus. The nucleus contains the protons and the neutrons. The negatively charged electrons are surrounding the nucleus of the atom in a circular orbit.
There are a total 118 elements discovered yet and they are placed in the periodic table. Thus, the periodic table is defined as the representation of chemical elements in order of their chemical properties. The number of elements is represented by their number of protons. In the periodic table seven rows of table are present known as periods and the columns are known as the group.
The elements in the periodic table are represented in the form of symbols where above the symbol atomic number is written and below the symbol atomic mass is written. The atomic number of the element represents the number of electrons. Number of protons and the number of electrons are the same.
Example: For the element helium, the atomic number is 2 so the number of electrons and the number of protons will be 2.

Note:
Even though the value of the number of protons and the number of electrons are the same but both are oppositely charged.
