What else can I help you with?
How are the mass number and the atomic number of an elment different?
The atomic number denotes the number of protons in an atom where the mass number gives the sum of protons and neutrons.
On what were the original atomic weights based?
The original atomic weights were based on the mass of hydrogen.
What is Atomic Mass unit based on?
The atomic mass unit (u) is based on the mass of a carbon-12 atom, which is defined as exactly 12 atomic mass units. This standard allows scientists to compare the masses of different atoms based on their atomic masses relative to carbon-12.
What is the atomic mass of gadolinium?
The atomic mass of gadolinium is 157.25 (which is the measured mass based on the various isotopes which occur in nature).
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.
Which element has a greater atomic mass A or B?
Element A has a greater atomic mass than element B if the atomic mass value of A is higher. The atomic mass represents the average mass of an element’s isotopes based on their abundance in nature.
What is the relative atomic mass of CU?
Copper is a meta element. Atomic mass of it is 64.
The atomic mass of an atom is based on a comparison with the mass of sulfur-32?
No, the atomic mass of an atom is based on the average mass of an element's isotopes weighted by their relative abundances. The atomic mass unit (amu) is equal to one-twelfth of the mass of a carbon-12 atom, not sulfur-32.
Standard atomic mass is based on what element?
Carbon 12 isotope weighs exactly 12 atomic mass units thank you the other person who said it was B is a douche
The atomic mass of an element is based on the PLUS?
The atomic mass of an element is based on the sum of the number of protons and neutrons in the nucleus of an atom. This value is typically given in atomic mass units (amu) and is an average of the isotopes of the element weighted by their abundances.
What is the average atomic mass of boron?
The average atomic mass of Barium is 137.33 amu.
The atomic mass unit is presently based on assigning an exact integral mass to an isotope of what?
The atomic mass unit is based on assigning an exact integral mass to the carbon-12 isotope. This isotope was chosen as the reference because it is abundant in nature and has a relative atomic mass very close to 12.
