Elements and Symbols to Learn
As a student of chemistry, you must eventually become familiar with the names and symbols of many
elements. Listed below are elements that you must be able to recognize. If given a symbol, you must be
able to spell the name of the element. If given the name of an element, you must be able to provide the
chemical symbol. Using your book, fill in the symbol of the element next to the name of that element.
You must also know the spellings of these elements as well. Elements that are in bold face type are those
that do not readily correspond with symbols of similar lettering.

Factor Label Method (Dimensional Analysis)
A method of problem solving that treats units like algebraic factors

Rules
1. Put the known quantity over the number 1.
2. On the bottom of the next term, put the unit on top of the previous term.
3. On top of the current term put a unit that you are trying to get to.
4. On the top and bottom of the current term, put in numbers in order to create equality.
5. If the unit on top is the unit of your final answer, multiply/divide and cancel units. If not, return to
step # 2.
6. As far as sig figs are concerned, end with what you start with!
