The Periodic Table

• Standard 2.1 Families of Elements
• Standard 2.2 Electron Configurations
• Standard 2.3 - 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

properties.

produce a colorless solution when dissolved in
water?

2. Cu(NO3)2
3. MnSO4
4. BaI2
5. SrCl2
6. CoS

5
Which family of metals is the most reactive?

1. alkali metals
2. alkaline earth metals
3. transition metals
4. rare earth metals
5. halogens
6. noble gases

6
Why dont the noble gases react with other
elements? Select all that apply.

1. They have the maximum amount of valence
   electrons.
2. They are all gases at room temperature.
3. They are already stable.
4. They dont have any valence electrons.
5. They are very rare.
6. They are too unstable.

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?

1. Oxygen is a gas and dubnium is a solid.
2. Elements with many protons in the nucleus are
   unstable and require lots of neutrons to reduce
   the pushing force between protons.
3. Dubnium has many more isotopes than oxygen.
4. There is no good explanation. The number of
   neutrons in an atom is completely random.

8
Which family of elements does bromine belong to?

1. alkali metals
2. alkaline earth metals

• Knows that the number of electrons in an atom
  determines whether the atom is electrically
