How do you get atomic mass?
Atomic mass is found by adding together the individual masses of the numbers of protons, neutrons, and electrons in the atom.--> Atomic Mass = protons + neutrons
What does the atomic mass equal?
mass of neutrons + mass of protons
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.
What is Berylium's Atomic mass?
Atomic mass is roughly the amount of protons and neutrons in an element. Berylium has 4 protons and 5 neutrons giving it an atomic mass of about 9. (9.012182 amu)
The atomic mass refers to the number of what?
The atomic mass is approximately the sum of the number of protons and neutrons.
What part of the nucleus determine the atomic mass for an element?
All parts of the nucleus, protons and neutrons if any, contribute to the atomic mass. The total number of protons and neutrons in an atom is its isotope mass number.
How does the atomic mass help you find the neutrons?
Atomic mass = mass of protons + mass of neutrons.
What does atomic mass do?
The atomic mass is equal to the number of protons plus neutrons. So if you know the atomic number then you can find out the number of neutrons Atomic # is the amount of Protons or Electrons Atomic Mass- Number of protons plus neutrons Atomic Mass-Atomic Number = Amount of neutrons
What does subatomic particles contribute to the value of atomic mass and atomic number?
protons is the same number as the atomic number always and protons plus the average number of neutrons makes up the atomic mass
What does mass do?
The Atomic Mass is equal to the number of protons plus neutrons. So if you know the atomic number then you can find out the number of neutrons Atomic # is the amount of Protons or Electrons Atomic Mass- Number of protons plus neutrons Atomic Mass-Atomic Number = Amount of neutrons
What particles make up the mass of the atom?
Protons and neutrons, the particles that make up atomic nuclei, are the ones responsible for almost all of the mass of an atom. As the electron has less than 1/1800th the mass of a proton, a whole flock of electrons won't significantly change the mass of an atom. We look to the protons and neutrons (called nucleons when they are being considered as components of an atomic nucleus) to contribute to the mass of an atom, and they will be considered when we derive the atom weight of an element.
How many neutrons are in an isotope of lithium if it has an atomic mass of ten?
No. of neutrons=Atomic mass -Atomic No.=10-3=7 It has 7 neutrons.
What 2 kinds of particles in an element when weighed together equal the atomic mass?
Protons and neutrons. Actually, the electrons contribute to the Atomic Mass as well. Its just that they are very small (about 1/1836th of a proton) in comparison with the protons and neutrons.
What do you get if you add one neutron to a hydrogen nucleus?
If you add the number of protons and neutrons in an atomic nucleus, you get the number of nucleons. This is usually a good approximation to the atomic mass in amu, since both protons and neutrons have a mass that's pretty close to one amu. The number will be slightly off, because electrons contribute as well, protons and neutrons don't have exactly the same mass, and there's something called the atomic mass defect that has to do with the binding energy of the nucleus, but it should be fairly close.
What do you get when you subtract atomic number from atomic mass?
mass #-atomic#=# of neutrons
What number is the atomic mass equal to?
Atomic mass is the number of protons and neutrons in an atom.
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.
