3. What is meant by an energy level in relation to electrons?

Energy levels describe the speed of electrons within an atom.

The number of energy levels in an atom depends on its mass and size.

Each electron can freely move between energy levels.

Energy levels in an atom refer to the specific orbits or shells where electrons are found. Each electron occupies a particular energy level, and these levels have a maximum capacity for the number of electrons they can hold as specified.

Explanation

4. What is an electron?

Elementary particle that has a negative charge of electricity and travels around the nucleus of an atom

Simple form of energy found in nuclear reactions.

Type of chemical bond present in covalent compounds.

Subatomic particle that carries a positive charge.

An electron is an elementary particle with a negative charge that orbits the nucleus of an atom. It is not a subatomic particle with a positive charge, a form of energy, or a type of chemical bond.

Explanation

An electron is an elementary particle with a negative charge that orbits the nucleus of an atom. It is not a subatomic particle with a positive charge, a form of energy, or a type of chemical bond.
