What particles make up the mass of an atom?
The number of protons
Atomic masses of any two elements contain the same number of?
protons and neutrons. This is because the atomic mass of an element is calculated by adding the number of protons and neutrons in the nucleus of an atom. The number of protons determines the element's identity, while the number of neutrons affects its stability.
Do atoms have neutrons in them?
Atoms of all elements can have neutrons in them. Only the element hydrogen has an isotope whose atoms do not contain neutrons, but all other isotopes of hydrogen have neutrons in them. In the heavier elements the number of neutrons always exceeds the number of protons in the atom.
An atoms mass number equals the combination of what two things?
The mass number of an element is equal to the sum of the elements neutrons and protons.
What does the atomic number of an atom made of?
An atomic nucleus contain protons and neutrons; protons and neutrons contain quarks and gluons.
Can two different element have the same number of proton?
No, the number of protons determines the element. Each element has a unique number of protons in its nucleus, which is what defines its identity. If two elements had the same number of protons, they would be the same element.
In periodic table of elements it is the sum of the number of protons and neutrons of an atom.?
The sum of protons and neutrons is the atomic mass.
Atoms of different elements always contain different number of what?

What addition of elements make up an atomic number of 33?
The atomic number 33 is for arsenic (As); the nucleus contain 33 protons and 42 neutrons.
What is the name for the number of protons and neutrons in atoms and elements?
mass number
What are elements having same number of protons and neutrons called as?
Carbon Number of Protons/Electrons: 6 Number of Neutrons: 6
How do the numbers of protons neutrons and electrons for an element compare?
In the neutral state, all atoms of the same element contain equal numbers of protons and electrons. However, most elements have atoms with different numbers of neutrons. These are called isotopes.
