Counting Atoms Flashcards
1
Q
How can we determine how many atoms are in a compound?
A
We can determine how many atoms are in a compound by looking at its chemical formula
2
Q
What are Subscripts?
A
If there is more than one atom, it is shown as a SUBSCRIPT
The subscript only applies to the element before it.
3
Q
What are Coefficients?
A
A COEFFICIENT (big number) shows the number of complete compounds that there are
The coefficient number applies to EVERY element in the compound.
4
Q
What are Subscripts over Brackets?
A
If there is a subscript outside of brackets, EVERYTHING inside of the brackets is multiplied by the subscript

A
Each element is represented by it’s SYMBOL
1 Capital letter PER symbol
