(B1) TILL ISOTOPES

Atom as a whole is electrically neutral because

• NO. OF PROTONS IS GREATER THAN THE NO. OF ELECTRONS
• NO. OF PROTONS IS LESS THAN THE NO. OF ELECTRONS
• NO. OF PROTONS IS EQUAL TO THE NO. OF ELECTRONS
• ALL THE MENTIOED OPTIONS

Atomic no. is the

• NO. OF NEUTRONS
• NO. OF PROTONS
• NO. OF NEUTRONS & PROTONS
• NONE

Total no. of Protons & Neutrons is known as

• ATOMIC NO.
• ATOMIC MASS NO.
• ATOMIC MASS
• NONE

Isotopes exist due to the difference in the no. of

• PROTONS
• ELECTRONS
• NEUTRONS
• ALL THE MENTIONED OPTIONS
