Read each question carefully and answer to the best of your ability. Use your knowledge of the periodic table to identify trends and properties of elements.
1. As you move from left to right across a period on the periodic table, what generally happens to the atomic radius?
It increases
It decreases
It stays the same
It varies unpredictably
2. Which of the following elements is most likely to have the highest electronegativity?
Lithium (Li)
Oxygen (O)
Sodium (Na)
Calcium (Ca)
3. The ability of an atom to attract electrons in a chemical bond is called .
4. Elements in the same group (column) of the periodic table have similar properties.
5. As you move down a group on the periodic table, the atomic radius generally .
6. Ionization energy generally increases as you move down a group.
True
False
7. Nonmetals tend to have higher electronegativity than metals.
True
False
8. Explain why elements in the same group have similar chemical properties.
9. Describe the trend in electronegativity as you move from left to right across a period and explain why this trend occurs.
