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 protons
The number of protons is equal to the atomic number.

∙ 8y agoBecause the atomic mass is the number of protons plus the number of neutrons and the atomic number is the number of protons. Subtract the protons, that leaves the neutrons.

To find the number of neutrons in an atom you would subtract what?
You would subtract the atomic number from the mass number.
What do you get when you subtract mass number from atomic number?
mass #-atomic#=# of neutrons
When you subtract the atomic number from the atomic mass it will give you the number of what?
the protrons, neutrons and electrons in a atom
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.
What Used to find the number of neutrons?
To find the number of neutrons in an atom, subtract the atomic number (number of protons) from the atomic mass number. Neutrons are uncharged particles found in the nucleus of an atom and their number can vary for a given element based on isotopes.
To find the number of neutrons in an atom you would subtract what?
You would subtract the atomic number from the mass number.
What do you get when you subtract mass number from atomic number?
mass #-atomic#=# of neutrons
What do you get when you subtract atomic number from atomic mass?
mass #-atomic#=# of neutrons
What do you have when you subtract the atomic no from atomic mass?
Atomic number is number of protons in an atom while atomic mass is the sum of protons and neutrons in an atom when you subtract you will get the number of neutrons in an atom.
In order to calculate the number of neutrons you must subtract the from the?
In order to calculate the number of neutrons, you subtract the atomic number (number of protons) from the atomic mass (rounded to the nearest whole number). Neutrons are important for stabilizing the atomic nucleus alongside protons.
How do you know the number of neutrons an atom has?
You can find the number of neutrons in an atom by subtracting the atomic number (number of protons) from the atomic mass number (rounded atomic weight). The atomic mass number represents the sum of protons and neutrons in the nucleus.
Atomic number of 2 and atomic mass of 4 how many neutrons?
To find the number of neutrons simply subtract the atomic number from the atomic mass. In this case there are two neutrons.
How do you calculate how many neutrons there are in an atom?
You can calculate the number of neutrons in an atom by subtracting the number of protons (which is the atomic number) from the atomic mass of the atom. The atomic mass is the sum of the number of protons and neutrons in the atom.
The mass number minus the atomic number?
If you subtract the mass number by the atomic number you get the number of neutrons.
How do you calculate the number of neutrons in boron?
To calculate the number of neutrons in boron, subtract the atomic number from the atomic mass. The atomic number of boron is 5, and the atomic mass is around 10.81. Therefore, boron has approximately 6 neutrons (10.81 - 5 = 5.81).
To determine the number of neutrons in an atom, what must be done?
To determine the number of neutrons in an atom, subtract the atomic number (number of protons) from the atomic mass number (rounded mass of the atom). Neutrons are particles found in the nucleus of an atom and carry no charge.
How do you calculate the number of neutrons an element has in its nucleus?
You need to find the atomic number, and the atomic mass. The atomic number i the number of PROTONS in the nucleus, the atomic mass, or mass number, is the number of PROTONS and NEUTRONS in the nucleus. To find the number of neutrons you subtract the atomic number from the mass number.
