which subatomic particles makes up most of?
320746
Along with protons, they make up almost all of the mass of the atom. The number of neutrons is called the neutron number and can be found by subtracting the proton number from the atomic mass number.

But, atoms themselves contain many subatomic particles, the three most important of which are protons, neutrons, and electrons. These particles do not vary in quality from one element to another; rather, what gives an element its distinctive identification is the quantity of its protons, called its atomic number.

Atoms. Atoms are everywhere! They make up everything around us and are the building blocks of life. They are made up of three different particles - protons, neutrons, and electrons.

These particles include atomic constituents such as electrons, protons, and neutrons (protons and neutrons are actually composite particles, made up of quarks), as well as other particles such as photons and neutrinos which are produced copiously in the sun.

The model suggests that atoms are made of smaller subatomic particles. 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.

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.

Protons and neutrons account for most of an atom's mass. These subatomic particles are found in the nucleus of the atom, where they form nucleons. Explain what keeps the electrons confined in the space surrounding the nucleus. The electrons are held within the atom by their attraction to the positively charged nucleus.

Protons, neutrons, and electrons are the three main subatomic particles found in an atom. Protons have a positive (+) charge. An easy way to remember this is to remember that both proton and positive start with the letter "P."

Originally Answered: Which subatomic particle contributes to the majority of the mass number of an atom? Protons and neutrons are within 1% of each other in mass, both being about 1000 times more massive than electrons.

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.

What subatomic particles would be found around the perimeter? Center (nucleus) – protons & neutrons. Perimeter - electrons 3.

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. Protons and Neutrons. Protons and neutrons make up the nucleus of an atom.

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.

Electrons are negatively-charged particles. But these basic atomic components are by no means the only known subatomic particles. However, quarks, muons and neutrinos, which make up major subatomic particles, will not be covered in this lesson.
