The mass number is the sum of protons and neutrons in the atomic nucleus.
Yes, atoms contain subatomic particles.
subatomic particles :)
Subatomic particles are protons, neutrons and electrons.
Atomic number is same as the number of protons and number of electrons.
Subatomic particles are particles that are smaller than an atom. Examples of subatomic particles include protons, neutrons, and electrons, which are the building blocks of atoms. Other subatomic particles include quarks, leptons, and bosons.
Neutrons and Protons.
electrons
Protons and neutrons.
Two particles are considered. they are protons and nrutrons
You think probably to mass number; the mass number is the sum of protons and neutrons.
In this case, the number 209 represents the sum of protons + neutrons.
Subatomic particles are: neutron, proton, electron.
The number of protons as well as the number of electrons.
Subatomic particles, like protons, neutrons, and electrons, are the building blocks of matter. They combine to form atoms, which then come together to create molecules and larger structures. In essence, the interactions between subatomic particles determine the composition and properties of all matter in the universe.
Subatomic particles are smaller than molecules and are the building blocks of atoms. Protons, neutrons, and electrons are examples of subatomic particles found in atoms. There are no known subatomic particles that are bigger than molecules.
The smallest part of a comet is likely the dust particles that make up its coma, which is the cloud of gas and dust that surrounds the comet's nucleus. These dust particles can be as small as a few micrometers in size.
No, photos are not made of subatomic particles. Photos are composed of photons, which are massless particles that carry electromagnetic force. Subatomic particles refer to particles like electrons, protons, and neutrons, which make up atoms.
