What isotope defines the atomic mass unit?
Carbon-12 isotope is used to define the atomic mass unit, which is equal to 1/12th of the mass of a carbon-12 atom.
The atomic mass of an atom with six electrons eight neutrons and six protons is?
You need to know the atomic number to find the element, and the atomic number equals the # of protons and electrons, which is 6. It is Carbon.
Why is the periodic number now based on the atomic number of elements and not mass number?
Because the number of protons defines the element, not the mass (you can have Hydrogen with 1 or 2 neutrons and it is still Hydrogen)
What the number of carbon in the atomic mass number?
The atomic mass number of an element represents the total number of protons and neutrons in the nucleus. Since the number of protons in an element's nucleus defines its identity, carbon, with the atomic number 6, always has 6 protons in its nucleus. Therefore, the atomic mass number of carbon is made up of these 6 protons and varying numbers of neutrons.
What statement accurately compares the trends in atomic number and atomic mass in the period gave?
In a period of the periodic table, atomic number increases sequentially from left to right as protons are added to the nucleus of each successive element. Atomic mass typically increases as well, although it does not always correlate directly due to the varying number of neutrons in isotopes. While atomic number defines the identity of an element, atomic mass reflects both protons and neutrons, leading to a generally increasing trend in mass alongside the atomic number across a period.
What is the difference between a substance's atomic number and it's atomic mass?
Atomic number defines as how many nmbr of electrons and protons d atom contain. No. of electron=No. of protons=Atomic Nmbr. Atomic mass defines d mass of total protons and neutrons(mass of nucleus) of an atom.
What isotope defines the atomic mass unit?
Carbon-12 isotope is used to define the atomic mass unit, which is equal to 1/12th of the mass of a carbon-12 atom.

You need to know the atomic number to find the element, and the atomic number equals the # of protons and electrons, which is 6. It is Carbon.
How do you figure out mass?
The Atomic Mass or weight of an isotope of an element is the total number of protons and neutrons in its nucleus. The number of protons defines which element it is, this is called the atomic number. For uranium for example it is 92, but the atomic weight can be from 233 to 238, and these different versions of uranium are called isotopes. See Periodic Table for more details of all the elements. Add the no. of neutrons and the no. of protons to get the atomic mass.

What is bigger the atomic mass or atomic number?
Atomic no.=no. of protons Atomic mass=no. of protons+no. of neutrons Hence, atomic mass is greater
What is the atomic mass-?
The atomic mass is the mass of a molecule, atomic particle or sub-atomic particle.
The mass of an atom usually expressed in atomic mass units is its?
Atomic mass
What is the atomic mass of silver?
The atomic mass (or weight) of silver is 107.8682 amu (atomic mass units)
What is the atomic mass of aluminum?
The atomic mass number of aluminum is 27. The atomic mass of aluminum is 26.98115386
