they r isobars
for example Argon-40 and calcium-40
same mass no and diff atomic nos = isobars
same atomic no and diff masses = isotopes

What is the name of carbon isotopes?
The stable carbon isotopes are carbon-12 & carbon-13. There are several other unstable isotopes.
True or false two isotopes of carbon are carbon-12 and carbon-14 theese isotopes differ from one another by two ELECTRONS?
False, different isotopes of the same element have different numbers of neutrons.
Which isotopes is most useful for dating wood and charcoal?
carbon-14
How are two isotopes of carbon with mass numbers of 12 and 14 different?
14 is higher then 12
Carbon with a mass number of 14?
There are three isotopes of carbon with mass numbers 12 (which is more than 99% of existing carbon), 13, and 14 (which is radioactive).
What is the name of carbon isotopes?

Carbon 12 and carbon 14 are called what of carbon?
Isotopes.
2 isotopes of carbon?
Yes Carbon 12, Carbon 13 and Carbon 14 are isotopes of carbon. Diamond and graphite are allotropes.
What are geological isotopes?
Carbon 12, carbon 13, carbon 14.
What are three isotopes and isobars of carbon?
isotopes of carbon are atomic no. 6 mass 12 , atomic no.6 mass 13 , atomic no. 6 mass 14
True or false two isotopes of carbon are carbon-12 and carbon-14 theese isotopes differ from one another by two ELECTRONS?
False, different isotopes of the same element have different numbers of neutrons.
How are isotopes used in carbon dating?
The ratio of carbon-14 (radioactive) to carbon-12 (nonradioactive) is measured.
What radioactive element is best suited for determining the age of wooden tools used by prehistoric humans during the last ice age?
Some of the isotopes used for this purpose are uranium-238, uranium-235 and potassium-40. However often the dates are not determined directly from isotopes in the fossils themselves, but instead from isotopes in layers of volcanic rocks above and below the fossils and the age of the fossils are estimated between these two measured dates.
How are the isotopes of an atom the same and how are they different?
Carbon-12 is the common carbon Carbon-14 sterilizing surgical apparatus
Which isotopes is most useful for dating wood and charcoal?
carbon-14
How many neutrons does the isotope carbon-14 have?
carbon 14 has 6 protons, 6 electrons, and 8 neutrons.
How are two isotopes of carbon with mass numbers of 12 and 14 different?
14 is higher then 12
