Question

Which of the following are isotopes and isobars.

12 6A, 136 B, 146 C , 14 7 D

Answer 1

Answer:

Isotope- Elements having same atomic number but different mass number.

Isobar- Elements having different atomic number but same mass number.

A.T.Q

Isotopes- A,B,C (Atomic number same; 6 but mass number different)

Isobars- C & D ( Atomic number different but mass number same; 14)

hope this will help you

Answer 2

Answer:

Isobar- C and D

Isotopes- A,B and C

Explanation:

• Isobar is that element which differs in the chemical property but has the same physical property. So, we can say that isobars are those elements which have a different atomic number but the same mass number.

As C and D has same mass number that is 14 but different Atomic number so they are isobars.

• Isotopes are the atoms in which the number of neutrons differs and the number of protons is the same. From the above definition of atomic mass and the atomic number, we can conclude that isotopes are those elements having the same atomic number and different mass number.

As A,B and C has same atomic number 6 but different mass numbers,so they are Isotopes.

hope you get that ☺️
