Is this a stable element Carbon atomic number 6?

Yes, carbon (atomic number 6) is a stable element with both stable and unstable isotopes. The most common stable isotope of carbon is carbon-12, which makes up about 98.9% of naturally occurring carbon.


Isotopes of elements?

Isotopes of elements are atoms with the same number of protons but different numbers of neutrons. This causes isotopes of the same element to have different atomic masses. Isotopes can be stable or unstable, with unstable isotopes undergoing radioactive decay.


What is the atomic number of phosphorous?

Phosphorus is non metal element. Atomic number of it is 15.


What is an icotope?

An isotope is a variant of a chemical element that has the same number of protons but a different number of neutrons in its nucleus. This results in different atomic masses for the isotopes of the same element. Isotopes can be stable or unstable, with unstable isotopes being radioactive and decaying over time. They have various applications in fields such as medicine, archaeology, and nuclear energy.


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.


What atoms with same atomic number but different atomic masses?

Isotopes are atoms with the same number of protons (same atomic number) but different numbers of neutrons, leading to different atomic masses. For example, carbon-12 and carbon-14 are isotopes of carbon with atomic number 6 but atomic masses of 12 and 14 respectively.


Atoms of same chemical element that have different atomic mass are known as?

Isotopes. They differ in the number of neutrons in the nucleus.


How many neutrons does the element fermium have?

Only isotopes Fr-221 and Fr-223 are natural.


Do the atomic number of isotopes differ?

No. Isotopes have the same atomic number, protons and electrons. They have different neutrons.


Is fluorines atomic number 9 when its stable?

All isotopes of fluorine, whether they are stable or unstable, have atomic number 9.


Which isotopes are most likely to decay?

Isotopes with a high atomic number and/or an unstable ratio of protons to neutrons are more likely to decay. Generally, isotopes further from the line of stability on the periodic table are more likely to undergo radioactive decay.


Atoms that have the same atomic numbers but different atomic weights are called what?

If they have the same atomic number but different mass, then they have a different number of neutrons, and they are called ISOTOPES.
