♻ WHAT IS ELEMENT?
➡ Element is a pure substance that can neither be decomposed nor be formed from simple substances by ordinary physical and chemical means.
♻ WHAT IS ATOMIC NUMBER?
➡ Atomic number is defined as the total number of protons and electrons present in the atom of an element.
♻ ATOMIC NUMBER - ELEMENT - ELECTRONIC CONFIGURATION ♻
13 : Aluminium : (2,8,3)
14 : Silicon : (2,8,4)
15 : Phosphorus : (2,8,5)
16 : Sulphur : (2,8,6)
17 : Chlorine : (2,8,7)
➡ So, clearly we observe that aluminium, silicon, phosphorus, sulphur and chlorine have 3,4,5,6,7 electrons respectively in their outermost shells.
➡ NOTE :- THE NUMBER OF ELECTRONS IN THE OUTERMOST SHELL OF AN ATOM IS ALSO KNOWN AS THE VALENCE ELECTRONS.
