Question

A particle that has a negative charge is?

1) neutrons
2) non-polar molecule
3) electrons
4) protons

Answer 1

The particle with a negative charge is the electron, which is a fundamental subatomic particle contributing to the atom's negative electric charge and chemical properties.

Step-by-step explanation:

A particle that has a negative charge is an electron. Electrons are subatomic particles with a negative electric charge of -1, which is equal but opposite to the charge of a proton, which is +1. Unlike neutrons, which carry no charge, and protons, which carry a positive charge, it is the electrons that are responsible for the negative charge in an atom.

Atomic structure consists of a nucleus composed of protons and neutrons, referred to as nucleons, surrounded by orbiting electrons. Protons are positively charged, neutrons are neutral, and electrons are negatively charged. These electrons orbit the positively charged nucleus and contribute to the chemical properties of the atom, though they contribute almost nothing to its mass since their mass is about 1/2000th of that of nucleons.

In summary, the correct answer to the question is 3) electrons, as they are the particles that have a negative charge.

Answer 2

Electrons are subatomic particles that carry a negative charge.

Step-by-step explanation:

The correct answer is 3) electrons.

Electrons are subatomic particles that carry a negative charge. They are fundamental particles and are one of the three main types of particles that make up atoms. Protons carry a positive charge, neutrons have no charge, and electrons have a negative charge. In an atom, the number of electrons orbiting the nucleus is equal to the number of protons inside the nucleus, resulting in a neutral atom with no net charge.
