Write the Electronic Configuration of Any One Pair of Isotopes and Isobars. - Science


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



Two isotopes of carbon are `""_6^12C" and """_6^14C`

The electronic configuration of `""_6^12C` is 2, 4.

The electronic configuration of `""_6^14C` is 2, 4.

[Isotopes have the same electronic configuration]

`""_20^40Ca" and """_18^40Ar` are a pair of isobars

The electronic configuration of `""_20^40Ca`  is 2, 8, 8, 2.

The electronic configuration of `""_18^40Ar`  is 2, 8, 8.

Explain Isobars with examples.

If the diameter of a carbon atom is 0.15 nm, calculate the number of carbon atoms which can be placed side by side in a straight line across the length of scale of length 20 cm long.

2 × 108 atoms of carbon are arranged side by side. Calculate the radius of carbon atom if the length of this arrangement is 2.4 cm.

Which of the following are isotopes and which are isobars ?
Argon, Deuterium, Calcium, Tritium, Protium

What are isobars ? Explain with an example.

The mass number of two atoms X and Y is the same (40 each) but their atomic number are different (being 20 and 18 respectively). X and Y are examples of :

The four atomic species can be represented as follows. Out of these, the two species which can be termed isobars are :





The atomic species A and B have different number of protons but the same number of nucleons. On the other hand, the atomic species X and Y have the same number of protons but different number of nucleons. Which pair is an example of isobars ? Why ?

Composition of the nuclei of two atomic species A and B is given as under  :

  A B
Protons : 18 20
Neutrons : 22 20

Give the mass numbers of A and B. What is the relation between the two species and which element or elements they represent ?

Which of the following pairs are isobars ?
(i) `""_26^58"A"`, `""_28^58"B"`

(ii) `""_35^79"X"`, `""_35^80"Y"`
Give reasons for your choice.
