4
$100 Answer from Trends Ionization Energy
5
$200 Question from Trends What happens to atomic radius going across the periodic table from left to right. Why?
6
$200 Answer from Trends Decreases because of the increased nuclear charge.

25
$200 Question from PT The modern periodic law states that properties of elements are a ______.
26
$200 Answer from PT periodic function of their atomic number
27
$300 Question from PT As you move from left to right through the transition elements in the fourth row, which energy level are additional electrons placed in?
28
$300 Answer from PT Third (3d)
29
$400 Question from PT What problems did Mendeleev have when he constructed his Periodic Table?
30
$400 Answer from PT Ge hadn’t yet been discovered, so he left a place for it Some elements (potassium, for example) did not “fit” according to their atomic mass
31
$500 Question from PT Why are the noble gases non-reactive?
32
$500 Answer from PT They have an octet of valence electrons.
33

50
$400 Answer from Elements As (Arsenic)
51
$500 Question from Elements Which is more active, K or Na? Why?
52
$500 Answer from Elements K It is larger, so the valence electrons are farther from the nucleus
