प्रश्न
Two atoms are said to be isobars if.
विकल्प
they have same atomic number but different mass number.
they have same number of electrons but different number of neutrons.
they have same number of neutrons but different number of electrons.
sum of the number of protons and neutrons is same but the number of protons is different.
उत्तर
sum of the number of protons and neutrons is same but the number of protons is different.
Explanation:
Isobars are the atoms which have same mass number (sum of number of neutrons and protons) but different atomic number (i.e. different proton number)
For example, 614C and 714N.
