Question

Which two particles are found in the nucleus of an atom?

neutrons and electrons
protons and electrons
protons and neutrons
neutrons and atoms​

Answer 1

Answer:

Protons and neutrons are found in the nucleus of the atom.

Step-by-step explanation:

Protons and neutrons are found in the nucleus of the atom, while electrons are outside of the nucleus.

Answer 2

Protons and neutrons

Step-by-step explanation:

Nucleus is the central dense part of the nucleus and consists of most of the mass of an atom.

An atom has three subatomic particles:

• Electrons
• Protons
• Neutrons

Electrons are negatively charged subatomic particles, protons are positively charged and neutrons are neutral.

Electrons are present in the energy shells outside to the nucleus and revolve around it.

Protons and neutrons are present in nucleus.

Number of protons and neutrons present in the nucleus together called mass number or atomic mass.

Therefore,

Atomic mass = No. of protons + No. of neutrons

Number of protons present in the nucleus is same as the number of electrons present outside nucleus.

Therefore,

No. of protons = No. of electrons = Atomic number
