What does it mean isotopes?
Isotopes are atoms of the same element but with a different number of neutrons.
How many types of helium there?
"Type" is ambiguous in this context. Do you mean isotopes? Or do you mean states of matter? (Helium has some exotic states of matter.)Wikipedia states that there are 8 helium isotopes, to of them (3-He and 4-He) stable."Type" is ambiguous in this context. Do you mean isotopes?

What does a higher percentage of daughter isotopes in rock mean?
A higher percentage of daughter isotopes present in a sample, the older the rock is.
The average amu of an atom is found by finding the mean of its what?
Isotopes
Is O radioactive?
If you mean oxygen: like most elements, it has both stable isotopes, and unstable (i.e., radioactive) isotopes. 16O, 17O and 18O are stable; the unstable (radioactive) isotopes include 15O and 14O.
Idotopes of the same element have different?
if you mean isotopes then isotopes of the same element have a different number of neutrons in the nucleus so have a different atomic weight.
Are iron elements stable?
Iron is an element, and there is only one element called iron (Fe). There are no iron element(s), but if you mean isotopes, then some iron isotopes are stable, and some aren't. No known element is stable in of it's isotopes.
The mean atomic mass of an element is 35.5 .Assuming the element has 2 isotopes of mass 25 and 27 respectively, The abundance of the isotopes with mass number 35 is?
90
Do isotopes of the same element differ in mass number?
isotopes just mean they have a different number of neutrons so if the..Mass number = # of protons + # of neutrons -they will have a different (greater) mass
Atoms of same chemical element that have different atomic mass are known as?
Isotopes. They differ in the number of neutrons in the nucleus.
What do you think nuclear chemists mean when they say that 8 20 and 50 are magic numbers for isotopes?
It is simply that among period 2 elements, oxygen (8) is one of the elements which has the largest number of isotopes, among period 4 elements, calcium (20) has the largest number of isotopes, and among period 5 elements, tin (50) has the largest number of isotopes. In fact tin has the largest number of isotopes overall.
Atoms of the same element that differ in the number of neutrons they contain are known as?
they are known as isotopes. Dont ask people to do your homework
