Most stable types of nuclei have an number of protons and an number of neutrons?
Most stable nuclei have a roughly equal number of protons and neutrons, which helps to balance the forces that hold the nucleus together. This balance of protons and neutrons helps minimize the nucleus's potential energy, making it more stable.
How does the ratio of neutrons to protons for stable nuclei change as atomic number increases from 1 to 82?
As atomic number increases from 1 to 82, the ratio of neutrons to protons in stable nuclei generally increases. For lighter elements, stable nuclei tend to have a neutron-to-proton ratio close to 1:1. However, as the atomic number increases, more neutrons are needed to offset the repulsive forces between the increasingly numerous protons, resulting in a ratio that can exceed 1.5:1 for heavier elements. This trend helps maintain nuclear stability amidst the growing electrostatic repulsion among protons.
Why do heavy elements neclei contain proportionally more neutrons than light element nuclei?
Heavy elements contain more protons, which repel each other due to their positive charge. Neutrons help stabilize the nucleus by adding nuclear binding energy without adding additional electrostatic repulsion like protons do. Therefore, heavy nuclei tend to have more neutrons to help balance out the increased number of protons.
Which series lists particles in order from smallest to the greatest mass?
The series that lists particles in order from smallest to greatest mass is: electrons, neutrinos, protons, and neutrons. Electrons are the lightest, followed by neutrinos, which have an extremely small mass but are still heavier than electrons. Protons and neutrons, which are components of atomic nuclei, have significantly greater masses, with neutrons being slightly more massive than protons.
Are neutrons smaller than protons?
no, they both have the same relative mass, this is why you add the number of protons and neutrons to get the mass number for the atom. The neutron is very slightly more massive than proton, by about the mass of an electron.
What does the nuclei of heavy atoms have that light atoms do not have?
Heavy atoms have more protons and neutrons in their nuclei compared to light atoms. This increases the nuclear charge and mass of heavy atoms, making them less stable and more prone to undergo radioactive decay.
What nuclei would be the most stable?
10 protons, 12 neutrons

Where does the weight of the nucleus mostly come from?
The nucleus is made up of protons and neutrons. Most of the elements with low atomic numbers are equally protons and neutrons. However, as elements get heavier they will have more neutrons than protons, and since each weigh the same amount (1 atomic mass unit) these nuclei will get most of their weight from the neutrons.
How does the ratio of nuetrons to protons for the stable nuclei change as atomic number increases from 1 to 82?
The ratio of neutrons to protons in stable nuclei generally increases as the atomic number increases from 1 to 82. This is because as the nucleus becomes larger and more complex, it needs more neutrons to provide the necessary binding energy to hold the protons together due to the repulsive force between protons. This helps to maintain nuclear stability.

Protons and neutrons, which are components of atomic nuclei, have significantly greater masses, with neutrons being slightly more massive than protons.
Lighter elements have more or less number of protons than neutrons?
Lighter elements tend to have neutrons equal to protonms or only a slight excess. Heavier elements have an excess of neutrons over protons
Are neutrons smaller than protons?
no, they both have the same relative mass, this is why you add the number of protons and neutrons to get the mass number for the atom. The neutron is very slightly more massive than proton, by about the mass of an electron.
What do a heavy nuclei need to remain stable?
Heavy nuclei need to have a balanced ratio of protons to neutrons to remain stable. They also need to have the strong nuclear force between nucleons overcome the electrostatic repulsion between protons. Additionally, the nuclei need to have a sufficient binding energy to hold the nucleus together.
What are the key differences between stable and unstable nuclei?
Stable nuclei have a balanced number of protons and neutrons, while unstable nuclei have an imbalance. Unstable nuclei undergo radioactive decay to become more stable.
