RAM Calculation Flashcards
1
Q
What is an isotope ?
A
An element with the same number of electrons but a different number of neutrons.
2
Q
Are the reactivity of isotopes of the same element the same?
A
Yes because they have the same electronarrangement.
3
Q
What does the different masses of atoms mean?
A
Physical properties of isotopes are slightly different
4
Q
What is the definition of a relative atomic mass of an element?
A
The relative atomic mass of an element is the average mass of its atom compared to 1/2 of the mass of carbon- 12 atom.
5
Q
Do isotopes have a decimal for relative atomic mass?
A
No!
6
Q
What is the RAM formula?
A
RAM = average mass of an atom x12/mass of one atom of c-12
7
Q
Why are the atoms positive ions?
A
So we can see the mass.
