Question

Composition of the nuclei of two atomic species X and Y are given
X Y
Protons = 6 6
Neutrons = 6 8
Give the mass numbers of X and Y. What is the relation between the two species?

Answer 1

Explanation:

GIVEN:

PROTONS AND NEUTRONS OF ELEMENT X IS 6 AND 6 RESPECTIVELY.

PROTONS AND NEUTRONS OF ELEMENT WHY IS 6 AND 8 RESPECTIVELY.

TO FIND:

MASS NUMBER AND RELATION BETWEEN X AND Y.

SOLUTION:

MASS NUMBER = PROTONS + NEUTRONS.

MASS NUMBER OF ELEMENT X = 6+6= 12

MASS NUMBER OF ELEMENT Y = 6+8= 14

ATOMIC NUMBER IS DEFINED AS THE NUMBER OF PROTONS OR ELECTRONS IN AN ATOM.

THE ELEMENTS X AND Y HAVE SAME ATOMIC NUMBER 6 AND THE MASS NUMBER VARIES.

SHOW THE RELATION BETWEEN X AND Y IS AN ISOTOPIC RELATION.
