Read each question carefully and answer to the best of your ability. Use your knowledge of periodic table trends to explain your reasoning.
1. Which of the following elements has the largest atomic radius?
Lithium (Li)
Fluorine (F)
Cesium (Cs)
Neon (Ne)
2. Which trend describes the increase in ionization energy across a period?
Electrons are added to new energy levels.
Nuclear charge increases, pulling electrons closer.
Shielding effect becomes more significant.
The number of valence electrons decreases.
1. is a measure of the ability of an atom in a chemical compound to attract electrons.
