The 12 in Carbon-12 designates the isotope which has an atomic mass of 12. This is the most abundant isotope of carbon. Carbon has an atomic number of 6, therefore it has 6 protons. Carbon 12, therefore has 6 neutrons. Carbon 14 is another isotope of carbon, still having 6 protons, but has 8 neutrons, so it has an atomic mass of (6 + 8 = 14). See related link for more information on carbon isotopes.
What else can I help you with?
How many years would it take for the mass of a 1.00 g sample of carbon12 to be reduce to 0.125g?
It will take practically forever. Carbon-12 is not radioactive.
How many carbon atoms are present in a mole of carbon12?
6.023 x 1023
How many neutrons are in the isotope of aluminum 29?
If the isotope existed, it would have 16 neutrons.
How many neutrons in the isotope of Aluminum 29?
If the isotope existed, it would have 16 neutrons.
What is a antonym for isotope?
The antonym for isotope is non-isotope. An isotope refers to atoms of the same element with different numbers of neutrons, whereas non-isotope would refer to atoms of the same element having the same number of neutrons.
Which measurement would help determine absolute dates by radiometric means?
The measurement of the ratio of parent isotope to daughter isotope would help determine absolute dates by radiometric means. This ratio provides a way to calculate the age of a sample based on the known decay rate of the parent isotope into the daughter isotope.
How do you find the atomic number of an isotope?
The atomic number of an isotope is always identical to every other isotope, otherwise, it would form a separate element.
The half-life of an element is important for?
The half-life of an isotope is how long it takes for half of the atoms in a mass to undergo radioactive decay. Say you have 40g of an elements isotope with a half-life of one year. After 1 year, there would be 20g of that isotope left, and 20g of a different isotope/element. After 2 years, there would be 10g, and so on...
How do you find the isotopes of an atom?
The atomic number of an isotope is always identical to every other isotope, otherwise, it would form a separate element.
What would remain if you remove 2 neutrons fronm nitrogen?
an isotope of nitrogen will be formed with two neutrons less compared to the starting isotope
If the isotope is given for calcium what is the formula?
An isotope has extra/fewer neutrons than the original atom. So if you know the isotope you can deduce the original atoms' formula.For Ca that would be:20 protons40 mass number
What is half of a radioactive isotope?
Half of a radioactive isotope is an atom that would have half of the atomic number of the radioactive isotope. In the case of radium-88 (88Ra), half of the radioactive isotope would be ruthenium-44 (44Ru). This assumes that the protons do not break down and that none are lost to additional reactions with other elements or compounds. Electrons can be lost along the radioactive chain, resulting in an ion of ruthenium rather than an electrically neutral atom.
