It is number six in the Periodic Table.
It is the name of the element with atomic number six. The word 'carbon' has no definite meaning.
An atom of Carbon has 6 protons in its nucleus.
In carbon-14, the number 14 refers to the total number of protons and neutrons in the nucleus of the carbon atom. Carbon-14 is an isotope of carbon that contains 6 protons and 8 neutrons, resulting in a total atomic mass number of 14.
Carbon's atomic mass is ~12.0107. All of those decimals at the end tell us that there is more than one isotope of carbon. If you round the number, you will find the most common isotope of carbon. (Carbon12)IUPAC recommend in this case the expression atomic weight, not atomic mass.The atomic weight of carbon (IUPAC Table, 2009) is [12,0096; 12,0116]. This mean that the atomic weight is variable between the above mentioned limits, depending on the type of the sample.
Atomicity means no: of carbon atoms present in its molecule. carbon has high catenation ability, so any no: of carbon atoms can join together to form a molecule. hence atomicity is also very high. If you mean atomic number, it is 6. If you mean atomic weight, it is 12.0107(8).
The numbers in uranium-238 and carbon-14 refer to the atomic mass of the isotopes. The number '238' indicates that uranium-238 has a total of 238 protons and neutrons in its nucleus, while the number '14' indicates that carbon-14 has a total of 14 protons and neutrons.
atomic number is 37
It's the mass of an atom expressed as a multiple of 1/12 of the mass of a carbon-12 atom at rest. Please see the link.
Do you mean same atomic number and different mass numbers? If so then these are known as ISOTOPES. All atoms of any given element will have the same atomic number (number of protons in the nucleus) as this is what makes the element what it is. It is the number of neutrons in the nucleus which varies and hence the mass number (the number of protons plus the number of neutrons). For eg Carbon has three ISOTOPES - carbon-12, carbon-13 and carbon-14. They all have atomic number of 6 (6 protons in their nucleii) but have different numbers of neutrons (6, 7 or 8 respectively) and therefore different mass numbers.
Beryllium Atomic number: 4 Atomic Mass: 9.012
If "heavier than" in the question is interpreted to mean "has an atomic mass greater than", the answer is nitrogen
The atomic number is the number of protons in the nucleus of the atom.
