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.
What two particles of the atom are added together to get the atomic mass?

Which particle determines the atomic number of an element?
The atomic number of an element is determined by the number of protons.
What is the element with104 neutrons?
Lutetium (Lu) has 104 neutrons To find this number for any element, take the atomic number (lutetium is 71 on the periodic table) and the mass number of the element and subtract to find neutrons. The atomic number represents the number of Protons and electrons in an atom, the mass number can be found by rounding the atomic mass. If you subtract the # of protons from the total it will tell you how many particles , or neutrons, are left in the nucleus of the atom.. The atomic mass of Lu is 174.967 amu Therefore 175 (total particles) -71 (proton particles)= 104 Neutron particles.
What is the atomic mass for magnesiam?
Magnesium is a meta element. Atomic mass of it is 24.
The atomic mass of an element is the weight of what subatomic particles?
The protons and neutrons.
For the element with atomic number 36 how many of each of the three subatomic particles are contained in this element the atomic mass of this element is 83.798amu?
The atomic number is 5becuse it is in the nuclise

Relation between subatomic particles and atomic mass unit?
protons and neutrons are subatomic particles and adding the two amounts together gives you the atomic mass unit
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.
The atomic mass of an element is the?
Roughly speaking, the number of protons plus the number of neutrons. To be precise, the atomic mass is defined as the mass in atomic mass units; an atomic mass unit is 1/12 of the mass of a carbon-12 atom. This atomic mass unit is approximately equal to the mass of a proton or neutron. However, protons and neutrons don't have exactly the same mass; also, when these particles get together, there is a so-called "mass deficit".
What are the two particles involved in the atomic mass of an element?
Protons and neutrons, both residing in nucleus
Which particle determines the atomic number of an element?
The atomic number of an element is determined by the number of protons.

Magnesium is a meta element. Atomic mass of it is 24.
What tells you how many atoms of an element there are?
the atomic mass, which is the mass of its protons and neutrons and electrons together
