Carbon is a chemical element with an atomic number of 6 and an Atomic Mass of about 12.011 atomic mass units.
What else can I help you with?
What are some differences between atomic mass and atomic number?
Atomic mass is how much it weighs, the atomic number is how many protons/electrons it has
Mass number - atomic number equals?
Mass number minus the atomic number equals the number of neutrons. Mass number is the number of particles in an atom that have significant mass. Electrons are assigned a value of 0 since the mass is so much smaller than protons and neutrons. Protons and neutrons are similar in mass and are assigned mass number of 1. The formula for calculating atomic mass atomic mass = # protons + # neutrons.
Why atomic mass is always greater than atomic number?
Atomic mass includes the total mass of protons, neutrons, and electrons in an atom. Since protons and neutrons contribute significantly to the mass of an atom, atomic mass is generally greater than atomic number, which represents the number of protons in the nucleus. Electrons have a much smaller mass compared to protons and neutrons, so they have less impact on the overall atomic mass.
What determines atomic mass?
the mass of an atom of a chemical element expressed in atomic mass units. It is approximately equivalent to the number of protons and neutrons in the atom (the mass number) or to the average number allowing for the relative abundances of different isotopes.
How is the atomic mass number of a nucleus changed by alpha decay or by beta decay or by gamma decay?
The mass does not change much. The Atomic number will increase though.

What is the atomic number and mass of carbon?
Carbon is a non metal element. Atomic number of it is 12.

What is carbon's atomic number and atomic mass?
(Relative is the relative to hydrogen bit) Relative Atomic Mass:12 Proton number:6 The actual mass depends on how much carbon you have.
What equals the number of neutrons plus the number of protons in an atom?
The sum of the number of protons and neutrons in an atom is known as the atomic mass. It is equivalent to the mass number of the atom, which represents the total number of protons and neutrons in the nucleus.
What is a atomic mass for?
the Atomic Mass is how much an element weighs

Distinguish between atomic number and atomic mass?
The Atomic Number of an element is equal to the number of Protons/Electrons in the nucleus and the Atomic Weight is approximately the total number of Protons/Electrons and Neutrons combined. Using Carbon as an example: Total Protons/Electrons = 6, therefore the Atomic Number is 6 Total Neutrons = 6, and the Atomic Weight is 12 Question? The Atomic Number of Lithium = 3 The Atomic Weight of Lithium = 7 How many Protons/Electrons? How many Neutrons? Answer: Protons/Electrons = 3 Neutrons = 4
How are mass number and atomic number related?
If there is only 1 isotope then they are equal. Many naturally found elements have various isotopes (different numbers of neutrons in the nucleus). Each isotope has a diffent mass, so the measured atomic weight is an average.
What is a sentence for atomic mass?
the atomic mass is how much an element weighs
