Question

Which of the following have similar chemical properties?

• A. Isotope
• B. Isobars
• C. Allotropes
• D. Both isotopes and allotropes

Answer 1

The correct option is A Isotope

Isotopes have similar chemical properties because all isotopes belong to the same element having same number of valence electron.
Isobars has different chemical properties as they different number electrons in them.
Allotropism is the property of some chemical elements to exist in two or more different forms, in the same physical state, known as allotropes of these elements. But they can have different chemical proporties.
