Question

Which subatomic particles are found in the nucleus of an atom of beryllium?
A. Neutrons and Protons
B. Electrons and Positrons
C. Electrons and Protons
D. Neutrons and Electrons

Please explain why the answer is correct in detail.

Answer 1

A. the nucleus carries a positive charge, and the electron cloud carries a negatuve charge. since neutrons carry no charge, the nucleus composed of neutrons and protons carry a positive charge.

Answer 2

$\boxed{{\text{A}}{\text{. Neutrons and Protons}}}$ are found in the nucleus of an atom of beryllium.

Further explanation:

Atom is the basic and fundamental unit of matter. It is the smallest unit of an element. A general representation of atom is $_{\text{Z}}^{\text{A}}{\text{X}}$, where symbol of the atom is indicated by X, atomic number is indicated by Z and atomic mass is indicated by A.

Each atom has a small and dense central part in it. This central part where most of the atomic mass is concentrated is called atomic nucleus. There are three subatomic particles in the structure of atom and these are protons, electrons and neutrons. Protons are the particles having positive charge, electrons are negatively charged and neutrons are neutral in nature. Protons and neutrons are located inside the nucleus of an atom whereas electrons revolve around it in definite circular paths, known as orbits.

Beryllium is an example of atom so it will have a nucleus similar to that in a normal atom. So neutrons and protons are present in the nucleus of beryllium atom and therefore option A is the correct answer.
