Which statement describes an electron?
it has a positive charge and is located in the nucleus.
it has a positive charge and is located in orbitals around the nucleus.
it has a negative charge and is located in the nucleus.
it has a negative charge and is located in orbitals around the nucleus.

The statement that describes the electron is .

Further Explanation:

The smallest particle that is the building block of matter is known as an atom. Most of the space in an atom is empty and its mass is concentrated inside a small region called the nucleus.

An atom is also written as , where A is the atomic mass or mass number, Z is the atomic number and X is the letter symbol of the element.

Protons, electrons, and neutrons are the three subatomic particles that are present in the atom.

Proton is the subatomic particle with a positive charge. It is equal to the atomic number (Z) of the element. Neutron is the subatomic particle with no charge. It is located within the nucleus of an atom. Protons and neutrons are collectively called nucleons because these are located in the nucleus of the atom.

Electron is the negatively charged subatomic particle. In a neutral atom, the number of electrons is equal to the number of protons present in the nucleus of an atom. These revolve around the nucleus in definite orbits.

Therefore electron has a negative charge and is located in orbitals around the nucleus.
