Carbon is a non metal element. Atomic Mass of it is 12.
What else can I help you with?
What is the atomic mass in carbon?
The Atomic mass Is 12
What is atomic mass unit?
The Atomic Mass unit is 1/12 from the atomic mass of the isotope carbon-12, in steady state.
What is the atomic no and atomic mass of graphite?
Atomic number 6, atomic mass 12.
What is the atomic mass of carbon 12?
The atomic mass of carbon-12 is defined as 12 atomic mass units (amu). This corresponds to the mass of a single carbon-12 atom relative to 1/12th of the mass of a carbon-12 nucleus.
What is the atomic mass unit?
The atomic mass unit (amu) is a unit of mass used to express atomic and molecular weights. It is approximately equal to the mass of a proton or neutron, and is defined as 1/12 the mass of a carbon-12 atom.
The atomic mass is the?
The expression atomic mass is used only for isotopes; the atomic mass is the mass of an atom expressed in unified atomic mass units - (1 amu = 1/12 atomic mass of carbon-12).For elements the expression is atomic weight; the unit is the same.
What element has an average atomic mass of about 12?
Carbon has an average atomic mass of about 12.
What is the assigned atomic mass of carbon-12?
The atomic number of any carbon isotope is 6, the number of protons in the nucleus of any carbon atom, irrespective of its mass number.
An atom has 11 protons and 12 neutrons Its atomic mass is?
The atomic mass of an atom with 11 protons and 12 neutrons is calculated by adding the number of protons and neutrons together. In this case, the atomic mass would be 11 (protons) + 12 (neutrons) = 23 atomic mass units.
What is the relation of atomic mass with atomic no 6 and atomic mass 12 of carbon?
Carbon has 6 protons. With carbon-12 (the most common isotope) there are 6 protons + 6 neutrons, which gives the atomic mass of 12.
What is Carbon-12 atomic mass?
12. The number 12 refers to the atomic mass. More precisely, to the sum of neutrons + protons; but this is usually close to the atomic mass. In the case of carbon-12, it is exact, by definition.
Standard for the atomic mass number?
An atom of carbon-12 has a mass of exactly 12 atomic mass units. This is now the standard.
