What does it mean isotopes?
Isotopes are atoms of the same element but with a different number of neutrons.
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.
What is meant by percentage purity?
Percentage purity refers to the measure of how much of a substance is truly the desired compound or element. It is calculated by dividing the mass of the pure substance by the total mass of the sample, then multiplying by 100. A higher percentage purity indicates a higher concentration of the desired substance in the sample.
What is the most common instrument used to measure isotope?
The most common instrument used to measure isotopes is a mass spectrometer. Mass spectrometry allows scientists to accurately determine the mass and abundance of isotopes in a sample. It works by ionizing the atoms in the sample and separating them based on their mass-to-charge ratio.
What does it mean if two atoms are isotopes?
If two atoms are isotopes, it means they have the same number of protons but different numbers of neutrons. Thus, they have the same atomic numbers, but different atomic masses.
What does it mean of fusionable isotopes?
Fusionable isotopes refer to the larger isotopes that are usually relatively stable.
What does it mean isotopes?
Isotopes are atoms of the same element but with a different number of neutrons.
With the mean absolute percentage error is a higher or lower number better?
The lower the better
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 it mean when someone calls you a farmers daughter?
it mean that you are a farmers daughter
The average amu of an atom is found by finding the mean of its what?
Isotopes
What does 'daughter of the heart' mean in an obituary?
'Daughter of the heart' in an obituary would mean not a biological daughter but loved just the same as if she were.
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.
What does hija mean in spanish?
It means 'daughter.'
What does daughter mean in french?
daughter is translated 'fille' in French.
What happens to the percentage of an income that is taxed when income rises and the tax is a proportional one?
The percentage of an income that is taxed will stay the same when income rises until that income reaches a certain point set by the government. A higher tax bracket may mean a higher portion of the income will be taxed.
