It really isn't elements that are stable or unstable, but isotopes. Carbon has both stable and unstable isotopes.

Is Neon atomic number 10 stable?
Neon is a metal element. Atomic number of it is 10.
Which element is a stable element?
A stable element is any non-radioactive element. All elements before element atomic number 84 (not including 84) - Polonium (Po) are stable elements.
What element has a atomic number of 6 and 7 neutrons?
Carbon: C-13 isotope, stable, 1.1% of all natural occurring carbon (98.9% C-12) Atomic number: 6 (number of protons in nucleus) Atomic mass: 13.0033 a.m.e. Mass number: 13 (= 6 protons + 7 neutrons in nucleus) Nonmetal
Mass number of carbon?
The atomic mass of elemental Carbon is 12.011. There are two stable isotopes with differing mass numbers: 12 (98,9%) and 13 (1,1%) and one semi-stable C isotope nr. 14 (half-life time 5730 yr.)
In what way are two isotopes of the same element different?
An isotope is simply a certain element with a different atomic mass, for example carbon 12 is the same element as carbon 13 because it has the same number of protons, but it has an atomic mass of 12 because it has a different number neutrons. On the periodic table, the atomic mass labeled is normally the average atomic mass, or the mass of the most stable isotope. So to answer your question two different isotopes of the same element have a different number of neutrons, but the same number of protons and electrons.
Is Neon atomic number 10 stable?
Neon is a metal element. Atomic number of it is 10.
What is atomic number and how is it used to distingunish one element from onother?
The atomic number is the number of protons in an atom (it also relates to the number of electrons in a stable atom). Each element has a unique number of protons, no matter what the isotope of that element is. For instance, carbon-12, carbon-13 and carbon-14 all have six protons - it's just the numbers of neutrons that varies. In this way you can tell immediately what element an atom belongs to by the number of protons.
If carbon has an atomic number of 6 is it stable?
Isotopes carbon-12 and carbon-13 are stable; the isotope carbon-14 is radioactive and unstable.
Is fluorine stable with an atomic number of nine?
Fluorine is a non metal element. Atomic number of it is 9.
Does atomic weight is same with atomic number?
Atomic weight is not the same as atomic number for any element except hydrogen; this is the only element that has a radioactively stable isotope with no neutrons.
Which element is a stable element?
A stable element is any non-radioactive element. All elements before element atomic number 84 (not including 84) - Polonium (Po) are stable elements.
Which element has an atomic mass of11?
Atomic mass numbers are not properties of elements overall, but only of particular isotopes of elements. The only stable element with an isotope with mass number 11 is boron. Beryllium and carbon also have isotopes with mass number 11, but these are radioactive.
Atomic mass number of carbon?
The Atomic number of Carbon is 6. The Atomic mass of Carbon depends on the isotope and may be from 8 to 22. Carbon 12 and Carbon 13 are the only stable isotopes of Carbon. Carbon 14 is the longest-lived unstable (radioactive) isotope. Only Carbon 12, 13 and 14 are found in nature.
What element has a atomic number of 6 and 7 neutrons?
Carbon: C-13 isotope, stable, 1.1% of all natural occurring carbon (98.9% C-12) Atomic number: 6 (number of protons in nucleus) Atomic mass: 13.0033 a.m.e. Mass number: 13 (= 6 protons + 7 neutrons in nucleus) Nonmetal

So to answer your question two different isotopes of the same element have a different number of neutrons, but the same number of protons and electrons.
How do you get the number of protons electrons and neutrons from the atomic mass number and atomic number?
Number of protons = atomic number Number of neutrons = Atomic Mass (rounded to the nearest whole number) minus the atomic number Number of electrons in a stable element = number of protons Number of electrons in an unstable element = atomic number minus the charge
