What else can I help you with?
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.
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.
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.
Why do some atoms have a higher molar mass than other atoms?
Atoms have different molar masses primarily due to variations in the number of protons and neutrons in their nuclei. Each element is defined by its atomic number, which corresponds to the number of protons, while the atomic mass reflects the total number of protons and neutrons. Heavier elements tend to have more protons and neutrons, resulting in a greater molar mass. Additionally, isotopes of an element can have different masses due to differing neutron counts.
Why do atoms of heavier elements generally contain more neutrons than protons?
because the protons and electrons HAVE to cancel out each other and ive knowtest that normally, there are around 1/2 as many neutrons then protons.
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.
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.
Why there are many neutrons than protons in metal atom?
I assume you mean "more neutrons than protons". It really depends what metal you are talking about. The lightest metal is lithium; it has 3 protons. One of its naturally occurring isotopes has 3 neutrons, another has 4 neutrons. In the case of heavier elements, the ratio of neutrons to protons increases; this is not directly related with the elements being "metals", just with the fact that they are heavier elements. The general idea here is that for heavier elements, the repulsive forces between protons become larger; more neutrons are then needed to provide stability, since protons and neutrons attract one another using the strong force, but don't have an electrostatic repulsion.
What is the band of stability in chemistry and how does it relate to the stability of atomic nuclei?
The band of stability in chemistry refers to the range of stable isotopes on a graph of the number of neutrons versus the number of protons in atomic nuclei. Isotopes within this band are more stable because they have a balanced ratio of neutrons to protons. Nuclei outside of this band may undergo radioactive decay to become more stable.
