What is nuclear binding energy?

• The energy required to disassemble the nucleus of an atom into its individual protons and neutrons.

• The energy released when a nucleus is formed from its individual protons and neutrons.

• The energy released when a nucleus undergoes radioactive decay.

• The energy required to break apart an atom into its electrons and nucleus.

What is the force that increases nuclear stability?

• The gravitational force

• The electrostatic force

• The strong force (nuclear force)

• The weak force

What is the unit of measurement for nuclear binding energy?

• Joules

• eV

• Watts

• Kilograms

What is the role of the strong force (nuclear force) in nuclear stability?

• The strong force (nuclear force) only affects the electrons in the nucleus.

• The strong force (nuclear force) holds the nucleus together and maintains nuclear stability.

• The strong force (nuclear force) causes nuclear instability.

• The strong force (nuclear force) has no role in nuclear stability.

What is the role of the electromagnetic force in nuclear stability?

• It holds the nucleus together by attracting protons and neutrons.

• It causes protons to repel each other, which can lead to nuclear instability.

• It has no effect on nuclear stability.

• It converts neutrons into protons and vice versa.

The basic model of an atom consists of which particles?

• Neutron

• Photon

• Electron

• Proton

• Pion

What is the central region of an atom called?

• The nucleus

• The core

• The nucleon

• The orbital
