Question

Atoms of a specific element that have the same number of protons but a different number of neutrons are called
a. isotopes.
b. DNA.
c. RNA.
d. compounds.

Expert Solution

Step 1

An atom is made up of protons, neutrons, and electrons. Protons and neutrons together called nucleons. Protons and neutrons make the entire mass of the atom. Electrons are distributed in the orbits around the nucleus.

Step 2

The atoms having the same number of protons and electrons but a different number of neutrons are termed isotopes. As the number of neutrons varies in the element due to which mass number of the atom of an element also varies. For example, uranium has two isotopes namely, uranium-235 and uranium 239.
