What is an isotope Give an example?

Answer 1

An isotope is an atom of a given element with a different mass. this means it must have a different number of neutrons, as changing the amount of protons would change the element. in short, an isotope is an atom with a special number of neutrons.

eg.

normal hydrogen-

1

H

1

deuterium (hydrogen with a neutron)

2

H

if you dont understand what im talking about just wiki it.

Answer 2

Isotopes are atoms of an element that have the same number of protons but different numbers of neutrons. For example, carbon-12 and carbon-14 are isotopes of carbon. Carbon-12 has 6 neutrons, while carbon-14 has 8 neutrons.

Answer 3

Natural isotopes of uranium: 234U, 235U, 238U.

Isotopes: atoms of the same element having identical number of protons and electrons but a different nunmber of neutrons.
