Relative Mass Flashcards
1
Q
What is an isotope?
A
atoms of the same element with different no. of neutrons and diff masses
2
Q
What is relative atomic mass?
A
The weighted mean mass of an atom of an element compared with 1/12th of the mass of an atom of C-12
3
Q
What is relative isotopic mass?
A
The mass of an atom of an isotope compared with 1/12 of the mass of an atom C-12
4
Q
What does the weighted mean mass take into account?
A
- The percentage abundance of each isotope
- The relative isotopic mass of each isotope
5
Q
Do isotopes react in different ways?
A
No - only electrons affect reaction so neutrons have no effect.
Difference in physics properties though
