This is a brief study guide for the Physical Science Unit 1 test.

To view all the posts covered in Physical Science Unit 1, use the “category” selector in the left hand column (below the posts in mobile devices) and select Physical Science Unit 1.

Topics you need to study:

The scientific method:scientific laws / theories / hypotheses
is science a collaborative effort?
distinguish between observation and opinion

Understand the difference between precision and accuracy

Is chemistry the study of matter? or of change? or of both?

Scientific Notation and  powers of 10. Be able to convert decimal numbers to scientific notation and vice versa. Be able to multiply and divide numbers in scientific notation by separately multiplying (dividing) the number parts and adding or subtracting the exponents.

Atoms, nuclei, number of protons, atomic mass units, atomic number

# of shells in Iodine, nitrogen etc  (this refers to the Bohr Shell Model)

You need to be able to write an Orbital pyramid diagram and develop electron configurations for any element up to Xe.

Determine an element’s number of valence electrons.

You need to be able to identify different types of elements, Also called representative elements,  depending which column of the periodic table they are in. The top element in a column or group is the representative element (it properties are representative of the elements in that column.


Be able to identify an element’s ‘group’ (alkali metal, alkali earth metal, transition metal, metals in general, semi-mentals ( metaloids), chalcogens, halogens, and noble gasses) by the element’s position in the periodic table.
