What are some examples of protons?
- 1 proton (p) - stable
- 1 neutron (n) - unstable
- 1 p + 1 n - stable (but easily broken up)
- 2 p - unstable
- 2 n - unstable
- 2p + 1 n - stable - this one is a surprise because the protons should be strongly repulsive because both are positive charges
- 1 p + 2 n - unstable - the 2 neutrons should be happy since they don’t repel each other electrostatically

Ernest Rutherford first used the term in 1920 to describe the nucleus of hydrogen. Although protons weren’t named until the 20th century, the existence of the proton was theorized in 1815 by William Prout.
Why do protons and electrons attract each other?
Because opposite charges attract each other, protons and electrons are attracted. Like charges repel each other, so two protons exert repulsion on each other. The amount of attraction between protons and electrons is equal in strength to the amount of repulsion between two electrons.
Why do protons and neutrons bind together?
Because both protons and neutrons occur in the atomic nucleus, they are collectively known as nucleons. While the positive electrical charge of protons causes them to repel each other, when protons and neutrons get close enough to each other, the strong nuclear force overcomes electrostatic repulsion. This allows them to bind together. Protons, like neutrons, are hadrons. A proton consists of still smaller subatomic particles called quarks. Each proton is made of three quarks (2 up quarks and 1 down quark).

How many protons are in a hydrogen atom?
As they say, if you’ve seen one proton you’ve seen them all. All protons are basically identical to each other, and all neutrons are identical to other neutrons. Both are composite particles consisting of 3 quarks. Both can be usually found inside atom nucleus (and a neutron will not survive long outside a nucleus). In hydrogen atom there is 1 proton. In Helium atom there are 2 protons and 2 neutrons. In heavier elements there are more.
Why are protons and neutrons together?
The neutrons and protons are together in a nucleus due the strong nuclear force which makes them to remain in the form. Proton-proton has repletion but the neutrons apply an even stronger force on the protons in a nucleus.
How are charged particles observed?
Charged particles are observed using the tracking ionization chambers placed in a magnetic field in order to measure also their momenta. Neutrons are observed indirectly, either by the energy momentum balance or by detecting their collsions with other charged particles or when causing fission of heavy nuclei.
Is a neutron a proton?
A neutron is a combination of proton and electron where the strong-force is very weak (at one of the two poles). It has a very, very, very narrow region of stability at either of the 2 poles.

The atomic mass has the different characteristic than atomic number. While the atoms in same element must have same atomic number, the atomic mass may differ.
What is the symbol for an atom?
Atomic number has the symbol of Z. This number will define the special characteristic of atom both physically and chemically. The atoms in the same type element will always possess the same number of protons. The number of protons along with number of neutrons also define the chemical properties of atom.
Why is proton therapy better than conventional radiation?
The proton therapy is more preferable than the conventional radiation using X-ray because the therapy can specifically target the tumors instead of killing the healthy tissue. The accuracy is vital because the wrong radiation to healthy tissue can cause unwanted effects.
What are the properties of atoms?
The number of protons along with number of neutrons also define the chemical properties of atom. The sum of proton and neutrons numbers is called as atomic mass. The atomic mass has the different characteristic than atomic number. While the atoms in same element must have same atomic number, the atomic mass may differ. It means that the atoms have the same number of protons, but different amount of neutron. We call this atoms as the isotopes. The example of isotopes is hydrogen element. Its isotopes are protium, deuterium and tritium. Here’re their differences: 1 Protium: has 1 proton, 1 neutron, 1 electron 2 Deuterium: has 1 proton, 1 neutron, 1 electron 3 Tritium: has 1 proton, 2 neutron, 1 electrons.
Why is the protons important?
Proton is really important in the atom structure. This part will determine the characteristic of atom which will then define the properties of certain element. As an example, the carbon atoms have the six protons and hydrogen atoms have one proton. We can see that different element will have different amount of protons.

How many quarks are in a proton?
proton are a baryon containing 2 up quark and 1 down quark assembled together by the strong influence of gluons . the charge of proton is +1, has come from the net charge of its constituent quarks . The nucleus of the most common i sotope of the h ydrogen atom (with the chemical symbol "H") is a lone proton.
What are the particles that hang out with the protons in the nucleus?
Neutrons are non-charged particles that hang out with the protons in the nucleus. They exist to hold the nucleus together, because if you try to confine a bunch of positive charges in one place, you're going to have a bad time. These neutrons and protons are responsible for the mass of the atom, and tell us what isotope of an element we're dealing with (e.g., chlorine-35 and chlorine-37 have the same number of protons, hence why they're both chlorine, but chlorine-37 has two more protons). If we change the number of neutrons we have a new isotope.
What does it mean when two atoms weigh as little as 2 nucleons?
2 atoms weighting as little as 2 nucleons can only mean that each atom is a neutron or a proton + electron pair.
Why do neutrons exist?
Neutrons are non-charged particles that hang out with the protons in the nucleus. They exist to hold the nucleus together, because if you try to confine a bunch of positive charges in one place, you're going to have a bad time.
What are electrons in chemistry?
Electrons are the negatively charged things (I don't want to call them particles for reasons that are for another answer entirely) that move around the nucleus. These electrons actually do all the heavy lifting with most chemical interactions, and they are what were usually concerned with when we look at chemical reactions and processes. There are covalent bonds, which are a result of two atoms sharing their electrons, and ionic bonds, where one atom “takes” the electrons and the atom it belonged to is stuck along for the ride.. Changing the number of electrons gives us a new ion.
