The Atomic Mass of an element is the sum of its protons and neutrons.
What else can I help you with?
Which two measurements are made for each isotope?
If you're talking about mass spectrometry, the measurements made for each isotope during the detection process are abundance and mass to charge ratio.
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
Mass number - atomic number equals?
Mass number minus the atomic number equals the number of neutrons. Mass number is the number of particles in an atom that have significant mass. Electrons are assigned a value of 0 since the mass is so much smaller than protons and neutrons. Protons and neutrons are similar in mass and are assigned mass number of 1. The formula for calculating atomic mass atomic mass = # protons + # neutrons.
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 actual atomic mass is greater than mass number?
Mass number = number of protons + number of neutrons in an atom
Which two measurements are made for each isotope?
If you're talking about mass spectrometry, the measurements made for each isotope during the detection process are abundance and mass to charge ratio.
The sum of the protons and the neutrons will tell the atomic what?
Atomic mass number of the atom. The best way to remember it is: the majority of the mass of an atom is made up of the protons and neutrons (the electrons are very light!), therefore the atomic mass number is the sum of the protons and neutrons.
What is the different between mass number and atomic number?
Atomic number is the number of protons within the nucleus of the element. Mass number is the total mass of the element (made from number of electrons, protons, and neutrons). You can calculate the approximate mass of the element by multiplying the respective mass of each component by its corresponding amount. However, there will be a discrepancy by the calculated amount and the real amount because some of the mass is converted into energy when the element is formed.
What year was the hr gardner mass model 732 made?
Need the serial number.
What mass number is americium?
The mass number of Am-241 is 241; each isotope has another mass 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.
Can mass be a number?
yes mass can be a number
What is the mass number for sodium?
the mass number of sodium is 23
What is the mass number for the element uranium?

The formula for calculating atomic mass atomic mass = # protons + # neutrons.
How do you find out the mass number?
Mass number = Number of protons + number of neutrons
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.
