Carbon-12 was assigned an exact Atomic Mass to act as the standard for atomic mass of all other elements
What else can I help you with?
What nuclide is used as standard relative scale for atomic masses?
Carbon-12 is used as the standard relative scale for atomic masses. This is defined as having a mass of exactly 12 atomic mass units (u). Other elements are compared to this standard to determine their atomic masses.
Which element has the greatest atomic mass Li Cl C?
Among these three elements, Cl has the greatest mass, as can be seen from any periodic table or other reference work that shows atomic masses.
What did Johann Dobereiner notice about the atomic mass of the middle element in a triad?
Johann Dobereiner observed that in his triads of elements, the atomic mass of the middle element was approximately the average of the atomic masses of the other two elements in the group. This observation suggested a relationship between the properties of elements and their atomic masses, laying foundational ideas for the development of the periodic table. His work highlighted an early attempt to categorize elements based on their similarities, influencing later chemists in their understanding of element relationships.
What is the atomic mass of a human?
The atomic mass of a human is the sum of atomic masses of all the elements that make up the body. On average, a human body is composed mostly of oxygen, carbon, hydrogen, and nitrogen, with trace amounts of other elements. The total atomic mass of a human is about 30 kilograms.
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
State the name and the mass of the isotope relative to which all atomic masses are measured?
The isotope used as the reference for atomic masses is carbon-12, with a mass of 12 atomic mass units (amu).
The current standard for atomic masses is?
The current standard for atomic masses is based on the Carbon-12 isotope. It is defined as exactly 12 atomic mass units (amu), with all other atomic masses determined relative to it. This standard allows for consistency in measurements and comparisons of atomic masses across different elements.
Why is the relative atomic mass of an element relative to carbon-12?
The relative atomic mass of an element is compared to carbon-12 because carbon-12 is used as a standard reference point for measuring atomic masses. This comparison helps scientists determine the mass of atoms of different elements in relation to each other.
What nuclide is used as standard relative scale for atomic masses?
Carbon-12 is used as the standard relative scale for atomic masses. This is defined as having a mass of exactly 12 atomic mass units (u). Other elements are compared to this standard to determine their atomic masses.

What is the law of traid?
A German chemist Dobernier observed relationship between atomic masses of several groups of three elements called traids.In these groups the central or middle element had atomic mass average to the other two elements.
What did Dalton used the lightest element as his standard for atomic mass?
Dalton used hydrogen as his standard for atomic mass because it is the lightest element and was convenient for comparing the masses of other elements.
What is the atomic mass of a human?
The atomic mass of a human is the sum of atomic masses of all the elements that make up the body. On average, a human body is composed mostly of oxygen, carbon, hydrogen, and nitrogen, with trace amounts of other elements. The total atomic mass of a human is about 30 kilograms.

Are two atoms of different elements because they have close but different masses?
An element is made up of only one type of atom. Atoms are only different from each other due to their atomic number - which is the number of protons. Different elements may have different relative atomic masses, but it is the differing number of protons in each atom that determines which element it is.
Why do chemists use relative comparisons of masses of atoms?
because atoms from each element is different. relative masses of atoms is like their identity. it gives information on their weight, their density, their number of subatomic particles(protons and neutrons) and etc, etc. most importantly, relative masses of atoms allows chemist worldwide to accurately communicate with each other the amount as well as the composition of compound used in their reactions.
