How the position of elements in the periodic table helps you predict its chemical properties? Explain with an example.

Question

Philoid · Accepted Answer

Position of elements in the periodic table gives a prediction of:

i. Ionization energy of the element.

ii. Electron affinity of the element

iii. Metallic and non-metallic properties.

iv. Electronegativity

For example: An element having atomic number = 9

Its group number is 2 and period number is 2.

This means the element belongs to non-metals.
