what is the three subatomic particles that make up 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.

Atoms consist of a nucleus containing protons and neutrons, surrounded by electrons in shells. The numbers of subatomic particles in an atom can be calculated from its atomic number and mass number.

An atom is the smallest unit of a element. They are made up of electron, neutrons, and protons which are all particles. ... A particle is often times viewed as a single bit of something. Often they are used when discussing subatomic particles like protons, neutrons, and electrons.

The Bohr model shows the three basic subatomic particles in a simple manner. Most of an atom's mass is in the nucleus—a small, dense area at the center of every atom, composed of nucleons. Nucleons include protons and neutrons.
1211802
Compare the three subatomic particles in terms of location in the atom, mass, and relative charge. Electrons surround the nucleus and have a negative charge and small mass relative to protons and neutrons. Most of an atom's mass is in its nucleus, which is the center and composed of protons and neutrons.

atoms are made of smaller substances referred to as. subatomic particles. an atom comprises what 3 smaller substances. neutrons, protons, electrons.

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.

Protons, neutrons, and electrons are the three main subatomic particles found in an atom. The element Na has 11 protons, 11 electrons, and 12 neutrons for a total of 34 subatomic particles.

The short answer is neutrons, protons and electrons, which together build atoms. Digging a little deeper protons and neutrons are each made of 3 quarks, held together by gluons. Electrons are believed to be elementary particles, with a an elementary minus charge and a very small mass.

The structure of the atom. An atom is the smallest unit of matter that retains all of the chemical properties of an element. ... Most atoms contain all three of these types of subatomic particles—protons, electrons, and neutrons.

The Atom Builder Guide to Elementary Particles Atoms are constructed of two types of elementary particles: electrons and quarks. Electrons occupy a space that surrounds an atom's nucleus. Each electron has an electrical charge of -1. Quarks make up protons and neutrons, which, in turn, make up an atom's nucleus.

An atom is the smallest unit of matter that retains all of the chemical properties of an element. ... Most atoms contain all three of these types of subatomic particles—protons, electrons, and neutrons. Hydrogen (H) is an exception because it typically has one proton and one electron, but no neutrons.

Science >> Chemistry for Kids. The atom is the basic building block for all matter in the universe. Atoms are extremely small and are made up of a few even smaller particles. The basic particles that make up an atom are electrons, protons, and neutrons. Atoms fit together with other atoms to make up matter.

In the middle of every atom is the nucleus. The nucleus contains two types of subatomic particles, protons and neutrons. The protons have a positive electrical charge and the neutrons have no electrical charge. A third type of subatomic particle, electrons, move around the nucleus.

Atoms consist of a nucleus made of protons and neutrons orbited by electrons. Atoms are the basic units of matter and the defining structure of elements. ... We now know that atoms are made up of three particles: protons, neutrons and electrons — which are composed of even smaller particles, such as quarks.

Most atoms have three different subatomic particles inside them: protons, neutrons, and electrons. The protons and neutrons are packed together into the center of the atom (which is called the nucleus) and the electrons, which are very much smaller, whizz around the outside. ... Most of an atom is empty space.
