What are the names of 2 nucleons?
The particles found in the nucleus are collectively called nucleons. Nucleons are protons and neutrons.
Why must nuclei with more than one proton also have neutrons?
Consider the nucleus of an atom like a magnet and the circling electrons as metal bullets. When there is 1 Proton and 1 Electron, the charges balance out. The pull in of the magnet and the pull away of the bullet keeps the bullet circling. If there are then 2 magnets, the bullet then does not have enough energy to keep circling, and it crashes into the center, creating a neutron. In order to balance the atomic attraction forces with electron repulisive forces, neutrons in the nuclei of atoms are formed by 'binding force'. This strong force exceeds the repulsiveness of a single proton/electron pair but does not exceed a double proton/electron pair. Therefore, Hydrogen with one proton can potentially have 1 or 2 neutrons, but Helium with two protons 'needs' a minimum of two neutrons for atomic stability.
What atom consists of more or less neutrons than protons?
Tritium, also know as hydrogen 3, has 2 neutrons and one proton
Why do heavy elements neclei contain proportionally more neutrons than light element nuclei?
It is for this reason that large nuclei contain proportionally more neutrons than light elements
Which is slight more massive then a proton?
Neutrons contain slightly more mass.

What causes something to be radioactive?
Atomic nuclei with more than 84 protons or a large neutron-to-proton ratio is unstable. These nuclei will lose alpha-particles (generally reduces the nucleus by 2 protons and 2 neutrons) or beta-particles (generally turns a neutron to a proton) until it becomes stable. This can take billions of years or a fraction of a second, depending on the isotope.
Which is slight more massive then a proton?
Neutrons contain slightly more mass.
Differentiate nuclear fusion from nuclear fission using diagram?
Nuclear fusion is when two nuclei join together and another different nucleus results. For example deuterium plus tritium (both hydrogen isotopes) fuse to give helium. The D nucleus is one proton and one neutron, the T nucleus is one proton and two neutrons. When they join the result is the He nucleus which has two protons and two neutrons, and so there is also a spare neutron ejected.Fission occurs with large nuclei like U-235 and Pu-239, the nucleus just splits apart forming the nuclei of two lighter elements (the total number of protons has to equate before and after), and also releasing spare neutrons. One or more of these spare neutrons can then be captured by another U-235 or Pu-239 nucleus, so that a chain reaction can proceed.You can find diagrams in Wikipedia
What mass do neutrons have?
Slightly more than that of a proton plus an electron.
What nuclear process is happening during the main sequence?
Nuclear fission. It realeases nuclear energy by spitting big atomic nuclei, usually those of uranium. Neutrons are fired at the nuclei. As the neutrons smash into the nuclei they split off more neutrons, which bombard other nuclei, setting of a chain reaction, which makes energy.
What makes up the nucleus of the atom?
There are only two stable subatomic particles, Protons and Neutrons. Protons: Positive charge, 1amu The "atomic number" of an element gives the number of protons in its nucleus. Neutrons: No charge, makes up rest of the atomic mass, 1amu each The nucleus of every element contains one or more of each kind of stable subatomic particle, except for hydrogen which has ONE proton, but no neutrons
Which two subatomic particles have about the same mass?
Composite subatomic particles (such as protons or atomic nuclei) are bound states of two or more elementary particles. For example, a proton is made of two up quarks and one down quark, while the atomic nucleus of helium-4 is composed of two protons and two neutrons.
Could a nucleus of more than one proton but no neutrons exist?
No , because the neutrons have the same particles as the nucleus.
