What is the relationship between the atomic number the mass and the number of neutrons and protons in an atom?
Glad you asked. Pull up a chair and we'll tackle this one. We need to do a little review before we confront the isotope issue. Ready? Then let's have at it. An atom is an atom, but it becomes a particular element when we know the number of protons in its nucleus. Each element has a unique number of protons in its nucleus, and that is what determines what element it is. Hydrogen has one, helium has two, etc. But the kicker is that, though each element has a specific number of protons, it can have different number of neutrons in the nucleus of one of its atoms and still be that element. Same element (same number of protons), but different numbers of neutrons. Different atomic configurations of a given element are called isotopes of that element. Take helium for example. It has two protons (which is what makes it helium), but it can appear with one or with two neutrons. Each of these is an isotope of helium, and each one is stable, meaning it will not spontaneously undergo any atomic transformation. One other thing is that there are about a million atoms of He-4 for every atom of He-3. There are other isotopes of helium with three, four and more neutrons, but these are artifically made and are unstable. They will decay in a fairly short time. Now we've covered isotopes. The mass number (or Atomic Mass number or nucleon number) is simply the number of protons plus the number of neutrons in an atom. That's all. If we talk about, say, an atom of U-235, which is a fissionable isotope of uranium, the 235 is the atomic mass number. The element uranium has the atomic number 92, which means that there are 92 protons in its nucleus. If we subtract that 92 from the 235, we get 143 as a result, and that will be the number of neutrons in the nucleus of that isotope of 92U. Simple and easy. One more example. Carbon has an atomic number of 6, and carbon-14 has 14 minus 6 = 8 neutrons in it. Now you've got the scoop on isotopes, mass numbers and neutron counts.

What does the nuclear stability graph illustrate about the relationship between the number of protons and neutrons in an atomic nucleus?
The nuclear stability graph shows that there is an optimal ratio of protons to neutrons in an atomic nucleus for stability. Nuclei with too few or too many neutrons compared to protons are less stable.
Where do we find the strong force?
The strong force is found within the atomic nucleus, holding protons and neutrons together. It is mediated by particles called gluons and is responsible for binding quarks together to form particles such as protons and neutrons.
Where are protons neutrons and electrons located?
Protons, neutrons and electrons are located in the atom. The protons and neutrons are located in the atomic nucleus; the electrons are around the nucleus, arranged in shells.
What term best indicates the total number of neutrons and protons in a particular isotope of an element?
The atomic mass number is the sum of the protons and neutrons of an element. The protons are given by the atomic number, so the neutrons can be found by subtracting the mass number by the atomic number. Both the mass and atomic numbers can be found on the periodic table.
How many neutrons does nobelium have?
157; you figure that out by taking the atomic mass (259) and subtract it by the # of protons (102) and the answer is the # of neutrons. ( the atomic #, # of protons, and # of electrons are always the same # 102 ). But each isotope of nobelium has a different number of neutrons, depending on the atomic mass.
Is there a relationship between the number of neutrons and protons in the atom is so what type?
Atomic number = number of protons + number of neutrons Mass number = number of protons + number of neutrons
What is the relationship between the atomic number and the number of neutrons?
The atomic number is equivalent to the number of protons; the number of neutrons is different for each isotope.
Is there any relationship between atomic mass and number of proteins and electrons?
Yes, there is a relationship between atomic mass and the number of protons and neutrons in an atom. The atomic mass is approximately equal to the sum of the number of protons and neutrons in an atom, as electrons have negligible mass compared to protons and neutrons. The number of electrons in a neutral atom is equal to the number of protons, in order to maintain a balanced charge.
What are the relationship between protons and neutrons in a atom?
The atomic number corresponds to the number of protons in the nucleus of an atom. It also corresponds to the number of electrons in a neutral atom. A neutral atom, you'll recall, is one where the number of electrons equals the number of protons in the nucleus of an atom. We remember that atoms often "loan out" or "borrow" electrons, so the electron count will not always equal the proton count.
What does the nuclear stability graph illustrate about the relationship between the number of protons and neutrons in an atomic nucleus?
The nuclear stability graph shows that there is an optimal ratio of protons to neutrons in an atomic nucleus for stability. Nuclei with too few or too many neutrons compared to protons are less stable.
What does the band of stability graph reveal about the relationship between the number of protons and neutrons in atomic nuclei?
The band of stability graph shows that there is an optimal ratio of protons to neutrons in atomic nuclei for stability. Nuclei with too few or too many neutrons compared to protons are less stable and tend to undergo radioactive decay.
What is the relationship between istotopes mas number and neutrons?
atomic mass of an atom = number of neutrons + number of protons For example the Deuterium isotope of Hydrogen Atomic mass number = 2 Atomic number = 1 The atomic number is the same as number of protons, so the Deuterium isotope has 1 proton atomic mass of an atom = number of neutrons + number of protons 2 = n + 1 n = 1
Why can you subtract the atomic number from the atomic mass and get the number of neutrons?
Not the atomic mass but the mass number (of course, these values are similar - not identical).The mass number is the sum between the number of protons and the number of neutrons. As a consequence:Number of neutrons for an isotope = Mass number - Number of protonsThe number of protons is equal to the atomic number.
How do you calculate the number of neutrons an atom of a specific element has?
You can calculate the number of neutrons an atom has by subtracting the atomic number (number of protons) from the atomic mass (rounded to the nearest whole number). Neutrons are the difference between these two values.
What is the relationship between a atomic number and an atomic mass number?
Atomic number: number of protons in a nucleus unique to an element Atomic mass number: number of protons + number of neutrons in a nucleus. May be a small range of values for a given element. Very roughly the atomic mass number is double the atomic number. For large elements it is more than double.
Subtracting the Atomic number from the atomic mass?
To find the number of neutrons in an atom, you would subtract the atomic number (number of protons) from the atomic mass (sum of protons and neutrons). The difference between the atomic mass and the atomic number gives you the number of neutrons in the atom.
How do you find the ratio of neutrons to protons?
The ratio of neutrons to protons in an atom can be calculated by subtracting the atomic number (number of protons) from the atomic mass (sum of protons and neutrons) of the atom. Mathematically, ratio of neutrons to protons = (Atomic mass - Atomic number).
