Question

Use proton number and the simple structure of atoms to explain the basis of the periodic table , with special reference to the elements of proton number 1-20

Answer 1

Step-by-step explanation:

The periodic table is based on the premise of the periodic law that has been modified.

The periodic law states that "the properties of elements are a periodic function of their atomic number".

So, the atomic number of an atom is the number of protons within the atom. Protons are positively charged particles within an atom.

They are used to delineate the position of the atoms on the periodic table. The periodic position of an element corresponds to its proton number.

For example:

Proton number Element

1 Hydrogen

2 Helium

3 Lithium

4 Beryllium

5 Boron

6 Carbon

7 Nitrogen

8 Oxygen

9 Fluorine

10 Neon

11 Sodium

12 Magnesium

13 Aluminum

14 Silicon

15 Phosphorus

16 Sulfur

17 Chlorine

18 Argon

19 Potassium

20 Calcium
