The three types of subatomic particles known as the proton, the neutron, and the electron have masses of 1.6726 × 10−27 kg, 1.6749 × 10−27 kg, and 9.1094 × 10−31 kg, respectively. As you can see, protons and neutrons have roughly the same mass, and both of their masses are significantly greater than that of an electron. So, for atoms containing more protons than neutrons, the protons will make up the greatest percentage of mass in that atom. For atoms containing more neutrons than protons, of which there are a whole lot more of, the neutrons will make up the greatest percentage of mass in that atom.
EDIT: Most of the mass in an atom comes from the energy in the Strong Force, which holds the nucleus together. Remember that mass and energy are equivalent.
What else can I help you with?
What are 3 subatomic particle?
The three most commonly referred to subatomic particles are the proton, the neutron, and the electron. Protons and neutrons are the subatomic particles that reside in the atomic nucleus. Electrons, however, are located outside of the nucleus.
Most atoms contain one or more?
electrons, protons, and neutrons. These subatomic particles make up the structure of an atom.
Mass of an atom is mainly due to nucleus?
Yes, the atomic weight of the protons and neutrons in an atom (the 2 particles that make up the nucleus) is 1 for each of them. The other particle in an atom is an electron. The atomic weight of an electron is 1/1840 so it is often considered negligible.
What are subatomic particles?
Generally speaking, subatomic particles are particles smaller than an atom. There are the three basic ones that make up atoms, and you probably already know that those are protons, neutrons and electrons.If we delve more deeply into the physics of the subatomic world, more and more particles will appear. At one point, there were literally dozens and dozens of different subatomic particles, and they created what was called a particle zoo. Since then, some newer ideas regarding the world of these tiny particles has arisen, and most of the particles in the zoo were recognized as composite particles made up of a just a few fundamental particles.Begin learning about subatomic particles by developing an understanding of protons, neutrons and electrons. Then find out what makes them up, and move from there to the number and nature of fundamental particles.
What are large positively charged subatomic particles called?
Strictly speaking, there is more than one kind of large, positively charged subatomic particle, but the one that matters the most is the proton.
What subatomic particles responsible for most of an atoms mass?
These particles are the protons and neutrons.
What subatomic particle or particles contributes the most to the mass of the atom?
These particles are protons and neutrons.
Subatomic particles with the most mass?
This particle is the neutron: 1,00866491600(43) amu.
Subatomic particles responsible for most of an atom's mass?
Protons and neutrons are subatomic particles that are responsible for most of an atom's mass. Protons have a positive charge, neutrons are neutral, and both are found in the nucleus of an atom. Electrons, which have a much smaller mass, orbit around the nucleus.
Does electron mean a subatomic particle with a negative charge?
Electrons are negatively charged subatomic particles, but have almost no mass. The mass of an electron is about 1/2000 that of a proton or neutron. The neutron is the most massive of the subatomic particles at 1.6755 x 10-24 grams.
Which two subatomic particles make up most of the atoms mass Where are they located?
These particle are neutrons and protons; they are located in the atomic nucleus.
When subatomic particles are most involved in chemical bonding?
These particles are the electrons.
What is the number of subatomic particles in sulfur?
Sulfur has 16 protons and electrons; the number of neutrons is specific for each isotope: Number of neutrons in a sulfur isotope = Mass number - 16
Which subatomic particles are most involved in forming chemical bonds?
Electrons
Which subatomic particles are most involedin chemial bonding?
just electrons
Which subatomic particles makes up most of the mass off the atom?
The major contribution to the mass of an atom is from protons and neutrons; electrons have a known but negligible mass.
What are the three most common subatomic particles?
These particles are: proton, neutron, electron.
