Atomic Mass Flashcards
1
Q
What does atomic mass represent?
A
The average mass of each isotope of the element, weighted according to the abundance of the isotope
2
Q
How is atomic mass calculated?
A
% of isotope in decimals x atomic mass of isotope + same calculation for all other isotopes
3
Q
What does atomic mass reflect?
A
The most abundant isotope
4
Q
What is mass spectrometry?
A
A technique that measures the mass of atoms by vaporizing atoms, colliding them with an electron beam to create positive ions, and measuring the amount those ions are bent by a magnetic field
5
Q
How is total intensity normalized?
A
Intensity of isotope / intensity of isotope + intensity of other isotopes x 100%
