What are the particles that determines the mass numbers?
Total number of protons and neutrons.
How do you determine the numbers of subatomic particles in an atom based on its identity?
Atomic number of a chemical element = Number of protons = Number of electrons Atomic mass of an isotope (mass number) - Number of protons = Number of neutrons
Do carbon and oxygen have the same atomic mass?
They don't contain the same number of particles because some particles are more dense than others making one atom and another atom the same mass but not have the same number of particles.
How do you find the number of particles in a compound when given the mass?
The mass is the number of particles. Especially with atoms on the periodic table. The atomic mass is the number of proton and neutrons in the nucleus.
What are the names and numbers of the particles in an atom of sodium?
The atomic number is 11 and atomic mass is 23. The number of protons and electrons in sodium is 11 and the number of neutrons is 12
If the number of charged and uncharged particles in the center of an atom are 7 and 8 respectively.What is the mass number of the atom?
The charged particles would be protons (+) and would have a mass of 7 ( which would also tell you its atomic number, making this element Nitrogen). If the uncharged particles are eight in number and like protons have a value of one, 7 + 8 = 15 for atomic mass. Since the actual atomic mass of N is 14.007, the difference in mass tells us that we are talking about an isotope of N.
Why are mass numbers whole numbers?
mass numbers are whole numbers because the mass number is number of protons in an atom, plus the number of neutrons. you can only have a whole neutron and or proton, therefore, all mass numbers are whole numbers.
What type of particle has an atomic number of 1 and a mass number of 1?
Of the common sub-atomic particles, both the proton and the neutron have mass numbers of 1.
What is the information given by the mass number?
Number or Nuclear Particles
Which subatomic particles have mass and re included in the calculation of the atomic mass number?
These particles are protons and neutrons; but to be correct the mass of electrons must be added.
What does the mass number equal?
The total number of subatomic particles in the nucleus
What particles make up the atomic mass number of an element?
The atomic mass number of an element is determined by mass of the nucleus of an atom. Therefore the particles that make up the nucleus determine the mass number. These particles are protons and neutrons.The mass of the protons and neutrons do not vary between elements, but the number of each in the nucleus varies between elements and between isotopes of the same element.
