Question

Isotopes of an element have.
(a) the same physical properties
(b) different chemical properties
(c) different number of neutrons
(d) different atomic numbers.

Answer 1

hey mate your answer is b).

in isotopes ,

-->same number of neutrons of one elements.

so c and d is not possible.

Answer 2

ANSWER:- different chemical properties

EXPLANATION:- 1. Option A: Because isotopes of the same chemical element have various mass numbers (for example, carbon-12, carbon-13, and carbon-14), they have varied physical properties (such as boiling points, melting points, etc.).
2. Option B: The quantity of electrons and their spatial arrangement determine the chemical properties of each element. The neutrons are not necessary for it. A given element's isotopes have the same number of electrons or protons but have different quantities of neutrons. Therefore, all isotopes share the same chemical characteristics. So, Option B, "Same chemical characteristics," is the accurate answer.
3. C. Atoms of an element that have different numbers of neutrons but the usual number of protons and electrons are referred to as isotopes. Their atomic numbers are identical as a result.
