1. The Periodic Table Standard 2.1 – Families of Elements
Standard 2.2 – Electron Configurations
Standard Ions

2. Standard 2.1
Understands how elements are arranged in the periodic table, and how this arrangement shows repeating patterns among elements with similar properties (e.g., numbers of protons, neutrons, and electrons; relation between atomic number and atomic mass)

3. An atom of magnesium would be the most similar to _______ in terms of its physical and chemical properties.
sodium
copper
neon
barium
silver
chromium 5

4. Select all of the following compounds that would produce a colorless solution when dissolved in water?
AlCl3
Cu(NO3)2
MnSO4
BaI2
SrCl2
CoS 5

5. Which family of metals is the most reactive?
alkali metals
alkaline earth metals
transition metals
rare earth metals
halogens
noble gases 5

6. Why don’t the noble gases react with other elements
Why don’t the noble gases react with other elements? Select all that apply.
They have the maximum amount of valence electrons.
They are all gases at room temperature.
They are already stable.
They don’t have any valence electrons.
They are very rare.
They are too unstable. 5

7. Which of the following best explains why oxygen has equal numbers of protons and neutrons in its atoms (8 and 8) while dubnium has 157 neutrons for only 105 protons?
Oxygen is a gas and dubnium is a solid.
Elements with many protons in the nucleus are unstable and require lots of neutrons to reduce the pushing force between protons.
Dubnium has many more isotopes than oxygen.
There is no good explanation. The number of neutrons in an atom is completely random. 5

alkali metals
alkaline earth metals
halogens
noble gases
