Chapter 2: Problem 6

Which subatomic particle is negative?

Short Answer

Expert verified

Electron

Step by step solution

Identify Subatomic Particles

First, recognize the three primary subatomic particles that make up an atom: protons, neutrons, and electrons.

Determine Particle Charges

Next, understand the charge of each subatomic particle. Protons are positively charged, neutrons are neutral (no charge), and electrons are negatively charged.

Identify the Negative Particle

Finally, identify which of the subatomic particles has a negative charge. From the previous step, it is clear that the electron has a negative charge.

Key Concepts

These are the key concepts you need to understand to accurately answer the question.

Electron

Electrons are one of the three primary subatomic particles found in an atom. They are incredibly small and have a negative charge. This is why electrons are often found orbiting the nucleus of an atom, where the positively charged protons reside. The attraction between the negatively charged electrons and the positively charged protons helps to hold the atom together. Electrons play a crucial role in many chemical reactions and are extremely important in the field of electricity. When electrons move from one atom to another, they create an electric current, which is the basis for much of modern technology.

Proton

Protons are another fundamental subatomic particle. Each proton carries a positive charge, which is exactly opposite to the charge of electrons. Protons reside in the nucleus of an atom, held together by the strong nuclear force. The number of protons in an atom's nucleus determines the element's identity and its position on the periodic table. This number is also known as the atomic number. For instance, hydrogen has one proton, while helium has two. Protons are much larger and heavier than electrons but smaller than neutrons. Together with neutrons, they make up most of the atomic mass.

Neutron

Neutrons are the third kind of subatomic particle found in an atom and are unique because they carry no electric charge. Like protons, neutrons are found in the nucleus and contribute significantly to the mass of the atom. Even though neutrons have no charge, they play a vital role in stabilizing the nucleus. The number of neutrons in an atom can vary even among atoms of the same element, leading to the formation of isotopes. Isotopes have the same number of protons but different numbers of neutrons. For example, carbon-12 and carbon-14 are two isotopes of carbon, with six and eight neutrons, respectively.
