what are the three main subatomic particles of an atom?
954
Subatomic particles include electrons, the negatively charged, almost massless particles that nevertheless account for most of the size of the atom, and they include the heavier building blocks of the small but very dense nucleus of the atom, the positively charged protons and the electrically neutral neutrons.

Subatomic particle, also called elementary particle, any of various self-contained units of matter or energy that are the fundamental constituents of all matter.

They're typically made up of three main parts: protons, neutrons and electrons. Think of the protons and neutrons as together forming a “sun”, or nucleus, at the centre of the system. The electrons orbit this nucleus, like planets. If atoms are impossibly small, these subatomic particles are even more so.

A typical atom consists of three subatomic particles: protons, neutrons, and electrons (as seen in the helium atom below). Other particles exist as well, such as alpha and beta particles (which are discussed below).

The nuclei of all atoms contain subatomic particles called protons . The nuclei of most atoms also contain neutrons . The masses of subatomic particles are very tiny.

Particles that are smaller than the atom are called subatomic particles. The three main subatomic particles that form an atom are protons, neutrons, and electrons. The center of the atom is called the nucleus. First, let's learn a bit about protons and neutrons, and then we will talk about electrons a little later.

Even though many super-tiny atomic particles exist, you only need to remember the three basic parts of an atom: electrons, protons, and neutrons. What are electrons, protons, and neutrons? Electrons are the smallest of the three particles that make up atoms.

An atom is composed of three types of subatomic particles: electrons, protons and neutrons. An atom has an equal number of electrons and protons and so is electrically neutral (i.e., has no electrical charge).

To calculate the numbers of subatomic particles in an atom, use its atomic number and mass number: number of protons = atomic number. number of electrons = atomic number. number of neutrons = mass number - atomic number.

A typical atom consists of three subatomic particles: protons, neutrons, and electrons (as seen in the helium atom below). ... Nucleons include protons and neutrons. All the positive charge of an atom is contained in the nucleus, and originates from the protons. Neutrons are neutrally-charged.

Neutrons and protons constitute almost all of an atom's mass. The third type of stable particle is the electron. Electrons have a negative charge but are extremely small and have a mass only 1/1850 that of a proton or neutron. They are so small that for practical purposes they do not contribute to the mass of the atom.

An electron is one of the most important types of subatomic particles. Electrons combine with protons and (usually) neutrons to make atoms. Electrons are much smaller than neutrons and protons. The mass of a single neutron or proton is more than 1,800 times greater than the mass of an electron.
