Rick uses an electronic air sampler to determine the amount of dangerous chemicals in the air.

Which functions of the air sampler confirm that it is an electronic tool?

Which element in the third period would you expect to have the larger atomic radius, sodium (na) or sulfur (s)? a. sodium, because it has a higher effective nuclear charge attracting electrons in fewer energy levels. b. sodium, because it has fewer protons attracting electrons in the same energy levels. c. sulfur, because it has more protons attracting electrons in more energy levels. d. sulfur, because it has a higher effective nuclear charge attracting electrons in the same energy levels.

Why are the trends and exceptions to the trends in ionization energy observed?
