Define Isotope
Atoms of the same elements with different number of neutrons same number of protons
What is the mass number also known as
nucleon number
Isotopes of the same element have the same and different of
same - chemical properties
different- physical (bp,mp)
What is instrument is used to determine the abundance of the various isotopes of an element
Mass spectrometer
On a mass spectrum what is on the x-axis and y-axis
y-axis percent abundance
x-axis m/z ratio
Define relative atomic mass
weighed average mass of an atom compared to 1/12th the mass of an atom of carbon -12
What are Radioisotopes
radioactive isotopes that are unstable due to the number of subatomic particles contained in the nucleus
What is the equipment that can be added to compounds to determine reaction mechanisms
Radioactive tracers
