rest all the statements are true as we have

A) Electrons orbit the nucleus rather like planets orbiting the Sun.

TRUE, because electrons can move in stationary orbit around the nucleus

C) Electrons can jump between energy levels in an atom only if they receive or give up an amount of energy equal to the difference in energy between the energy levels.

Difference amount of energy is lost or absorbed by the electron in form of photons

D) An electron has a negative electrical charge.

Charge of an electron is given as -1.6 \times 10^{-19} C

E) Electrons have very little mass compared to protons or neutrons

Mass of an electron is given as

m_e = 9.11 \times 10^{-31} kg

mass of proton or neutron

m_p = 1.67 \times 10^{-27} kg

Answer: The correct statements are:

  • The atoms are very attracted to one another.
  • The atoms are held tightly together.

Explanation:

Solid state: In this state, the molecules are closely packed and cannot move freely from one place to another that means no space between them and the intermolecular force of attraction between the molecules are strong.

In solid substance, the particles are very close to each other due to this the intermolecular forces of attraction are strongest.

The key point about solid are:

  • The atoms are very attracted to one another.
  • The atoms are not moving freely.
  • It will not spread out evenly to fill any container.
  • The atoms are held tightly together.
  • The forces of attraction are strong to bring molecules together.
  • The atoms are close and in fixed positions.
