The atomic mass of an element is based on the PLUS?
yes
What element is used to find the atomic mass of all the elements?
Atomic mass of an element is calculated based on the mass of it's protons and neutrons. This is why we get isotopes. But I think you are talking about Carbon; the periodic table is based on 12.
What is the atomic weight for the element potassium?
The standard of atomic weight 39.0983 +/- 0.0001 u
What is the atomic mass for magnesiam?
Magnesium is a meta element. Atomic mass of it is 24.
What does the atomic mass minus atomic number tell you about the element?
Atomic mass minus atomic number will give you the average number of neutrons in that element. Bear in mind that atomic mass is based on the actual weight of that element, which is the result of whatever isotopes appear in nature; it is rarely based on only a single isotope.
What is the standard atomic mass units for isotopes?
It depends on the element.
The atomic mass of an element is based on the PLUS?
yes
What did Dalton used the lightest element as his standard for atomic mass?
Hydrogen

What is the atomic weight of titanium?
The standard atomic weight of Titanium (Ti) is 47.867(1) g·mol−1
What is the atomic weight for the element potassium?
The standard of atomic weight 39.0983 +/- 0.0001 u
What is atomic mass and what relationship does it have with the periodic table?
The atomic mass of an element is based on the number of nucleons (neutrons + protons) in the atom of the element. It is usually the weighted average of the atomic masses of isotopes of the element, weighted according to the abundance of the isotopes on earth.In most cases, but not all, the atomic mass of an element increase as the atomic number increases.
What is the atomic mass for magnesiam?
Magnesium is a meta element. Atomic mass of it is 24.
What does the atomic mass minus atomic number tell you about the element?
Atomic mass minus atomic number will give you the average number of neutrons in that element. Bear in mind that atomic mass is based on the actual weight of that element, which is the result of whatever isotopes appear in nature; it is rarely based on only a single isotope.
Which element has the atomic mass of 126.9045?
The element is Iodine (I). It has an atomic mass of about 126.9.
What is the difference between the atomic number and the atomic mass?
Atomic mass is the mass of 1 mole of the element. Atomic number is the number of protons the element has
Which is the average of the mass numbers of an element's isotopes?
the Atomic Mass
