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.

What can be added or taken away from an atom to change the atomic mass?
The atomic mass of an atom can be changed by adding or removing subatomic particles. By adding or removing protons, neutrons, or electrons, the atomic mass will be altered. Changing the number of protons will change the element, while changing the number of neutrons will create isotopes of the same element.
The atomic number increases but the atomic mass stays the same?
The atomic number increases but the atomic mass stays the same after the emission of a beta particle by a radioactive atom.
What happens to the mass number as you add more protons?
As you add more protons to an atom, the mass number, which is the total number of protons and neutrons in the nucleus, generally increases. Each added proton contributes one unit to the mass number, while the number of neutrons may also change to maintain stability. Consequently, as the atomic number (number of protons) increases, the mass number typically increases as well, reflecting the larger nucleus.
How does the atomic mass change when a proton is added to its nucleus?
Since the atomic mass consists of protons and neutrons, adding a proton would add one unit to the atomic massguessing that the number of neutrons doesn't change.
Why is the atomic mass the same as the total number of protons and neutrons in the nucleus?
The atomic mass is the sum of the number of protons and neutrons in the nucleus because protons and neutrons have a mass of approximately 1 atomic mass unit each. Electrons are much lighter and do not significantly contribute to the overall mass of the atom.
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.
What can be added or taken away from an atom to change the atomic mass?
The atomic mass of an atom can be changed by adding or removing subatomic particles. By adding or removing protons, neutrons, or electrons, the atomic mass will be altered. Changing the number of protons will change the element, while changing the number of neutrons will create isotopes of the same element.
How do the number of protons change as atomic number increases by one?
the number of protons change because of the more protons you add on
How many protrons and neutrons are in iodine?
you can find the number of protons by looking at the atomic number (53), as the number of protons does not change between isotopes. You can find the number of neutrons by subtracting the atomic number from the Atomic Mass (131), therefore, iodine-131 has 53 protons and 78 neutrons.
Is it true that the nucleus is an atomic particle that has no atomic change?
the nucleus is made of protons and neutrons together. the protons have a positive charge and the neutrons have no charge [electrons circle the nucleus and have a negative charge]
The atomic number increases but the atomic mass stays the same?
The atomic number increases but the atomic mass stays the same after the emission of a beta particle by a radioactive atom.

What is the number of protons and neutrons called?
The number protons in an atom is called the atomic number (it is this number that tells us which element the atom is). The number of neutrons in an atom can change, but the term for the amount of neutrons is called an isotope. The number of protons and neutrons added together is called the atomic mass.
What happens to the mass number as you add more protons?
As you add more protons to an atom, the mass number, which is the total number of protons and neutrons in the nucleus, generally increases. Each added proton contributes one unit to the mass number, while the number of neutrons may also change to maintain stability. Consequently, as the atomic number (number of protons) increases, the mass number typically increases as well, reflecting the larger nucleus.

Why does an atomic number increase?
If you mean looking at the next element on the table then the mass would increase. However, the atomic number is only the number of protons in an atom and is not a true indicator of atomic weight. Variations in Neutron count can cause differences in atomic weights.
Why does Calcium have different mass numbers but same atomic number?
Atomic numbers are determined by the number of protons an atom has. The mass number is determined by the number of protons and neutrons. While the number of protons can't change (as the element itself would change), neutrons can and do vary. These are called isotopes.
