Question

Write the electronic configuration of any one pair of isotopes and isobars.​

Answer 1

Since all the isotopes of an element have identical electronic configuration containing the same number of Valence Electrons therefore all the isotopes of an element show identical chemical properties.. Isobars: Atoms of different elements with atomic number for the same mass number are called isobars.

Answer 2

${ \underline{ \boxed{ \large{ \bf{ \blue{Question}}}}}}$

Write the electronic configuration of any one pair of isotopes and isobars.

${ \underline{ \boxed{ \large{ \bf{ \blue{Answer}}}}}}$

Pair of isotopes :

$\bf{^{35}CL}$17 and $\bf{^{37}CL}$17

Electronic configuration of these isotopes.

= ＫＬＭ

2,8,7

Pair of isobars :

$\bf{ ^{40}AR18\: and \: ^{40}CA20}$

Atomic number of AR = 18

Electronic configuration of

${ \bf{^{40} AR18}}$

= ＫＬＭ

2,8,8

Atomic number of CA = 20

Electronic configuration of $\bf{ ^{40}CA20}$

=ＫＬＭ

2,8,8
