select all true statements.
the electron has a relative charge of 1-.
electrons will vary in charge depending on the element it came from.
an electron is extremely small.
the electron is emitted by atoms in a cathode - ray tube.
the electron from a gold atom is the same as one emitted by an aluminum atom.

Explanation:

1. Electrons have a relative charge of 1-. This is a fundamental property of electrons.
2. Electrons do not vary in charge depending on the element. Their charge is always - 1 elementary charge.
3. Electrons are extremely small in mass and size compared to protons and neutrons.
4. In a cathode - ray tube, electrons are emitted by the cathode (negative electrode) and travel towards the anode (positive electrode).
5. All electrons are identical regardless of the atom they come from. So an electron from a gold atom is the same as one from an aluminum atom.

Answer:

The electron has a relative charge of 1-.
An electron is extremely small.
The electron is emitted by atoms in a cathode ray tube.
The electron from a gold atom is the same as one emitted by an aluminum atom.
