Read each question carefully and provide the best answer based on your understanding of periodic table trends.
1. Which of the following elements has the largest atomic radius?
Lithium (Li)
Sodium (Na)
Potassium (K)
Rubidium (Rb)
2. As you move across a period from left to right, what generally happens to the ionization energy?
It increases
It decreases
It remains constant
It first decreases then increases
3. Electronegativity generally as you move down a group in the periodic table.
4. The ability of an atom to attract electrons in a chemical bond is called .
5. Nonmetallic character increases from left to right across a period.
True
False
6. Generally, metallic character increases as you move down a group.
True
False
7. Explain why atomic radius generally decreases across a period.
8. Describe the relationship between ionization energy and metallic character.
Refer to the image below for the next question.
9. Using the trends you have learned, identify which element (from the image) would likely have a higher electronegativity: the element in the top right corner of the periodic table or the element in the bottom left corner. Explain your reasoning.
