Protons. This determines what material the element is.

∙ 12y agothe atomic weight depends on the number of protons and neutrons. for example, carbon has 6 protons and 6 neutrons(C6 isotope). hence the Atomic Mass is 6+6=12 a.m.u

∙ 11y agoThe atomic weight reflects the average weight from the original chemical and all of its isotopes.

How was the atomic number and the atomic mass determined?
the atomic number is determined by looking above top of the letter[s] on an element on the periodic table of elements
What indicates the total number of protons and neutrons in an atom?
The mass number of an isotope indicates the total number (the sum) of protons and netrons in an atom.The number of protons is determined by the atomic number.The number of neutrons can be found by subtracting the atomic number from the mass number.
What element has the atomic number of 168?
The element with the highest atomic number is Ununoctium (total quantity that has ever existed: three atoms), and its atomic number is 118. Thulium has an atomic weight of 168.9342.
Atomic mass is determined by the number of protons plus the number of?
Atomic mass is determined by the number of protons and neutrons in an atom's nucleus.
What is the difference between the mass number and the atomic number of an element?
The difference between the atomic number and the mass number is that the atomic number is the number of protons in the nucleus of an atom of that element. The mass number is the total number of protons and neutrons in the atom.Atomic number = number of protonsMass number = total number of protons + neutrons
What determines the atomic number of a substance?
The atomic number is the number of protons in the nucleus of an atom, while the atomic mass is the total mass of the nucleus (both protons and neutrons)
How was the atomic number and the atomic mass determined?
the atomic number is determined by looking above top of the letter[s] on an element on the periodic table of elements
What is the total number of an element of a atomic number?
The atomic number is the number of protons (which is the same as the number of electrons) of an element
The atomic number is determined by?
The atomic mass is the can be determined by the number of protons in an atom. Remember that a proton has an atomic mas number of 1 AMU (atomic mass unit). (The total mass of an atom is the protons, neutrons and electrons combined.)
What indicates the total number of protons and neutrons in an atom?
The mass number of an isotope indicates the total number (the sum) of protons and netrons in an atom.The number of protons is determined by the atomic number.The number of neutrons can be found by subtracting the atomic number from the mass number.
The atomic number for an element is the total number of subatomic particles?
False; the atomic number is the total number if protons in the nucleus only.
Atomic mass is determined by the number of protons plus the number of?
Atomic mass is determined by the number of protons and neutrons in an atom's nucleus.
What element has the atomic number of 168?
The element with the highest atomic number is Ununoctium (total quantity that has ever existed: three atoms), and its atomic number is 118. Thulium has an atomic weight of 168.9342.
What is the atomic mass in an element?
The atomic mass in an element is the total number of protons and neutrons in an atom's nucleus.
What is a atomic number in a element?
The atomic number of an element refers to the number of protons in the nucleus of the atom of that element, and is unique to each element. The atomic weight is the weight of an atom of the element compared with the weight of a single proton, and consists of number of protons and neutrons in the nucleus of the atom of that element, and different atoms of the same element can have different numbers of neutrons, and therefore more than one atomic weight: it is usually given as an average. the atomic number on an element is simply the number of protons and electrons in the element. however, it is not the total number of them.
How chemists know the atomic masses of elements in the periodic table?
I am pretty sure it is the weight of the element, but do not quote me on that. Google it!
How do you calculate neutrons for elements in the periodic table?
them mass number of an element is the total amount of nuetrons and protons in the element , and the atomic number is the amount of protons ( and electrons) in the element simply subtract the atomic number from the mass number and you'll have the number of neutrons in the element hope this helped x
