The mass of an element tells you the total mass of protons and neutrons combined together. (It theoretically includes everything including electrons, but since electrons are so small, they generally do not make a big difference to the final mass). As for the atomic number, it is equivalent to the number of protons in an element. Ex Chlorine's atomic number is 17, and it has 17 protons and 17 electrons.

∙ 11y agoBy knowing mass number of the elements we can easily find out the number of neutrons presen in the nuclei.Physical properties of elements somewhat depends on mass number.

How do you find the mass number of an element?
The formula for mass number is number of neutrons = mass number - atomic number. Mass number can also be referred to as nucleon number.
What is the mass number for the element uranium?
The atomic weight of uranium is 238,02891(3) atomic mass units. The mass number is the total number of nucleons (protons an neutrons) in the nucleus; the mass number is different for each isotope: 234U: mass number 234 235U: mass number 235 238U: mass number 238
How can you get the mass number and atomic number of element?
We can find atomic mass and mass number in chemical elements. Atomic mass is about weight of the atom. Mass number is about total of neutrons and protons.
Why do you subtract the atomic number from the mass number?
We can find atomic mass and mass number in chemical elements. Atomic mass is about weight of the atom. Mass number is about total of neutrons and protons.
What is the difference between mass number atomic mass and atomic number?
We can find atomic mass and mass number in chemical elements. Atomic mass is about weight of the atom. Mass number is about total of neutrons and protons.
Can mass be a number?
yes mass can be a number
In order to calculate the number of neutrons you must subtract the from the?
Number of neutrons = Mass number - atomic number
How do you find the mass number of an element?
The formula for mass number is number of neutrons = mass number - atomic number. Mass number can also be referred to as nucleon number.
How do you find the number of neutrons from the mass number?
Atomic mass is the number of protons in an atom mass number is the number of protons plus neutrons in an atom the number of neutrons would equal the mass number minus the atomic number.
What is the mass number for the element uranium?
The atomic weight of uranium is 238,02891(3) atomic mass units. The mass number is the total number of nucleons (protons an neutrons) in the nucleus; the mass number is different for each isotope: 234U: mass number 234 235U: mass number 235 238U: mass number 238
How can you get the mass number and atomic number of element?
We can find atomic mass and mass number in chemical elements. Atomic mass is about weight of the atom. Mass number is about total of neutrons and protons.
Why do you subtract the atomic number from the mass number?
We can find atomic mass and mass number in chemical elements. Atomic mass is about weight of the atom. Mass number is about total of neutrons and protons.
Why is the atomic mass number not a whole number?
We can find Atomic Mass and mass number in chemical elements. Atomic mass is about weight of the atom. Mass number is about total of neutrons and protons.
How do you find out the mass number?
Mass number = Number of protons + number of neutrons
What is the difference between the atomic number mass number and atomic mass?
We can find Atomic Mass and mass number in chemical elements. Atomic mass is about weight of the atom. Mass number is about total of neutrons and protons.
What is the difference between mass number atomic mass and atomic number?
We can find atomic mass and mass number in chemical elements. Atomic mass is about weight of the atom. Mass number is about total of neutrons and protons.
Why actual atomic mass is greater than mass number?
Mass number = number of protons + number of neutrons in an atom
