Relative Atomic Mass Flashcards
1
Q
What is RAM?
A
Relative Atomic Mass.
2
Q
Where is RAM found on the Periodic Table?
A
Below the name of the atom?
3
Q
Can RAM be measured in units?
A
NO, there are no units as it is a comparative number.
4
Q
What are isotopes?
A
Same atoms (atomic number) but a different mass number (amount of electrons). They are different percentages of the atom.
5
Q
How do isotopes relate to RAM?
A
The isotopes and their percentage are needed to calculate the RAM.
6
Q
How is RAM calculated?
A
The atomic number of each isotope is timesed by the percentage;
(20%) (10%) (70%)
eg Cl (34) Cl (35) Cl (36)
RAM = (34x0.2) + (35x0.1) + (36x0.7)
= 35.5
This should be similar to the one shown on the periodic table.
