• A. They have different atomic numbers.
• B. They have same electronic configuration.
• C. They have same number of neutrons.
• D. All of the above

Answer 1

The correct option is A They have different atomic numbers.

The electronic configuration is drawn from the atomic number. As isobars have different atomic numbers, they have different electronic configurations too.

The number of neutrons = Mass number - Atomic number.

Since, atomic number is different it has a different number of neutrons.
