What would happen if the nucleus were made of only protons?

Answer 1: Indeed, if a nucleus only has protons, it will be unstable, and split up, simply because protons all carry positive charges (same charges repel each other due to the Coulomb interaction ). Neutrons can stabilize a nucleus, because they roughly act like bonds between protons.

Can a nucleus have only protons?

Moreover, a nucleus with only protons does exist: 2He, 3Li. Then: to have a nucleus with only neutrons is no possible because of the nuclear force interaction.

What happens when there are too many neutrons protons in the nucleus?

Beta decay occurs when a nucleus has too many neutrons and too few protons (the neutron to proton ratio is too high). The nucleus becomes more stable by changing a neutron into a proton and an electron ( particle). Notice that beta decay produces a nucleus with one more proton but with the same number of nucleons.

Why does a nucleus need neutrons Why can’t it just consist of protons?

Because the neutrons only experience the nuclear strong force and no repulsive force, nuclei with a mixture of protons and neutrons are most stable than ones with just protons.

What will happen if one proton is added to an atom?

If you add or subtract a proton from the nucleus, you create a new element. If you add or subtract a neutron from the nucleus, you create a new isotope of the same element you started with. In a neutral atom, the number of positively charged protons in the nucleus is equal to the number of orbiting electrons.

What happens if you add protons to an atom?

Atoms always have an equal number of protons and electrons, and the number of protons and neutrons is usually the same as well. Adding a proton to an atom makes a new element, while adding a neutron makes an isotope, or heavier version, of that atom.

Can neutrons exist alone?

Mononeutron: An isolated neutron undergoes beta decay with a mean lifetime of approximately 15 minutes (half-life of approximately 10 minutes), becoming a proton (the nucleus of hydrogen), an electron and an antineutrino. Its existence has been proven to be relevant for nuclear structure of exotic nuclei.

What happens when an element has too many protons?

The nuclei of radioisotopes are unstable, so they constantly decay and emit radiation. In elements with more than 83 protons, all of the isotopes are radioactive.

Which type of decay occurs if there are too many protons?

Beta decay
Beta decay occurs when, in a nucleus with too many protons or too many neutrons, one of the protons or neutrons is transformed into the other.

What would happen if there were no neutrons in the nucleus?

Simply, if there are no neutrons, the protons would get separated from the atom by repelling each other and thus the nuclei will be left alone. Therefore there will be no further elements.

What force holds the protons and neutrons together in a nucleus?

The strong force
The strong force binds quarks together in clusters to make more-familiar subatomic particles, such as protons and neutrons. It also holds together the atomic nucleus and underlies interactions between all particles containing quarks. The strong force originates in a property known as colour.

Why are protons and electrons not in the nucleus?

Further, electrons are fermions with half integer spin. In contrast, protons are bosons (with integer spin) and would behave entirely differently to electrons and couldn’t sit in shells round a nucleus in the manner of electrons. Then they wouldn’t be electrons or protons as such an arrangement in physically impossible.

What happens when a neutron decays inside the nucleus?

A last comment has to do with nuclear beta decay. This is basically when a neutron decays into a proton, an electron, and an electron anti-neutrino. If this occurs inside a nucleus (rather than for a free neutron), the electron is inside the nucleus during some short part of its trajectory.

What would happen if protons were 8000 times heavier than electrons?

The protons, being 8,000 times heavier than the electrons, would accelerate 8,000 times less by the mutual attractive force between them, and thus it’s “orbit” in its “shell” would be tiny, while the electrons’ “orbit” in the “nucleus” would be very much larger and faster.

How are electrons attracted to the nucleus of an atom?

The nucleus of an atom consists of bound protons and neutrons (nucleons). The negatively-charged electrons are attracted to the positively-charged protons and fall around the nucleus, much like a satellite is attracted to the gravity of the Earth.
