Examples (in the sense of non-radioactive): helium, oxygen, beryllium, caesium, lanthanum etc.
The element carbon.
half life
none, uranium itself is unstable, there are no stable elements after bismuth; and even some researchers suggest that bismuth is an unstable radioactive element with a halflife approaching twice the age of the universe.
Not by itself. The mass number is the sum of the numbers of protons and neutrons in he nucleus for each isotope of the element, or for elements with more than one stable isotope is an average depending on the natural abundance of the stable isotopes of the element.
A stable element is any non-radioactive element. All elements before element atomic number 84 (not including 84) - Polonium (Po) are stable elements.
People say they have made the element unahexium but hasn't been confirmed and even if there has been and element confirmed its only stable for a few milliseconds before it decays into more stable elements.
ionic
carbon, oxygen
a stable element is an element which have been able to complet its octect rule, i.e the electron of its outermost shell is complet, this is what is called a stable element
Fluorine is a stable element.yes.
gold is a stable element,which means it does not readily combine with other elements
the element is stable.
