What is the meaninq of two isotopes stable and unstable isotopes?
Isotopes are atoms of the same element with different numbers of neutrons. Stable isotopes have a balanced number of protons and neutrons, meaning their nuclei do not decay over time. Unstable isotopes, also known as radioactive isotopes, have an imbalance of protons and neutrons, causing their nuclei to decay and emit radiation over time.
How is electrons and mass number related?
it isn't - the number of electrons in an atom will be the same as the proton number of that atom, but the mass of an atom includes the number of neutrons, and in every stable element heavier than hydrogen, the number of neutrons is the same as or greater than the number of protons. Also, the mass will vary between isotopes of the same element, which will contain the same number of protons and hence electrons but a different number of neutrons. Generally, in stable nuclei, as the number of electrons in an atom in creases, the mass increases as well, but these are not directly linked as to be stable, heavier nuclei require a greater proportion of neutrons in the nuclei so will have a greater mass to electron number ratio
How many neutrons are in the nucleus of a atom?
Atomic nuclei are composed of protons and neutrons. The atomic number of an element shows the number of protons in a nucleus of an atom of that element, while the atomic mass shows the average number of nucleons (either a proton or a neutron) in nuclei of that element. There can be an average because, unlike proton number, neutron number can vary from isotope to isotope. For example, carbon can have 6 or 7 neutrons and still be stable, but it always has to have 6 protons, or else it'd be a different element. Because atomic mass is equal to the number of protons and neutrons, one can find the number of neutrons by subtracting the number of protons from the total number of nucleons in a given isotope. To do this, subtract the atomic number from the atomic mass.
How do the numbers of protons and neutrons compare in stable atoms?
The majority of stable atoms have slightly more neutrons than protons, but the numbers are similar. The biggest exception is hydrogen, which has a stable isotope having one proton and no neutrons. Many of the lighter elements have stable isotopes in which the number of protons and the number of neutrons is the same. But as the elements get heavier, we increasingly find that stable isotopes have more neutrons than protons. This is an understandable pattern. Protons, all of which have a positive charge, repel each other. It is the neutrons which act as a kind of nuclear glue, holding the nucleus together against the repulsive force that protons exert on each other. As the nucleus gets bigger, more neutrons are needed to hold it together.
An equal number of protons and neutrons typically results in an atom that is?
Often, but not always, atoms with an equal number of protons and neutrons in the nucleus are stable and not radioactive.
What Nuclei would be stable?
70 protons, 98 neutrons
What Nuclei would be most stable?
70 protons, 98 neutrons
What nuclei would be the most stable?
10 protons, 12 neutrons
What do a heavy nuclei need to remain stable?
More neutrons than protons.
Which of the following nuclei would be the most stable A. 10 protons , 14 neutrons B. 10 protons, 15 neutrons C. 10 protons, 13 neutrons D. 10 protons, 12 neutrons.?
(Explanation): remember that if an atom has less than 20 protons, the closer the number of neutrons and protons are, the more stable it is. Since 10 is closest to 12 out of these options, D is the correct answer.

How does the ratio of nuetrons to protons for the stable nuclei change as atomic number increases from 1 to 82?
because it becomes more complex and the nuclei has to mange more neutrons Sources: Science Teacher
Why is a larger nucleus not as stable as a smaller nucleus?
A smaller nucleus is generally more stable. Below are some general rules: # (Except for really small nuclei) All stable nuclei contain a number of neutrons that is equal to or greater than the number of protons. # Nuclei with too few or too many neutrons is unstable. # If a nuclei has even numbers of nucleons, it's generally more stable. # Nuclei with "magic numbers" usually tend to be more stable.
How many protons in niobium?
There are 41 protons in Niobium. The atomic number is the same as the number of protons.
What is an element that is equal to its number of protons and neutrons?
A stable one.
How many neutrons are in the nucleus of a atom?

The atomic number of an element shows the number of protons in a nucleus of an atom of that element, while the atomic mass shows the average number of nucleons (either a proton or a neutron) in nuclei of that element. There can be an average because, unlike proton number, neutron number can vary from isotope to isotope. For example, carbon can have 6 or 7 neutrons and still be stable, but it always has to have 6 protons, or else it'd be a different element. Because atomic mass is equal to the number of protons and neutrons, one can find the number of neutrons by subtracting the number of protons from the total number of nucleons in a given isotope. To do this, subtract the atomic number from the atomic mass.
