Question 19 (1 point) In general, as you move across a period in the periodic table from right to left: (1) the atomic radius (2) the effective nuclear charge (3) the first ionization energy decreases, increases, increases increases, increases, decreases increases, decreases, increases increases, decreases, decreases decreases, increases, decreases Question 20 (1 point) Greater effective nuclear charge decreases increases remains unchanged is variable answers c & d are possible Ca K As > Ge> Kr Kr > Ge As > K> Ca Ge As > Kr > K > Ca Ca > Ge As > Kr Kr > As > Ge > Ca > K Question 21 (1 point) Of the following, which answer lists Ca, K, As, Ge and Kr in order of decreasing atomic radius? OK K> ок nuclear charge radius Question 22 (1 point) Electrons in the 1s subshell are much closer to the nucleus in Kr than in Ne due to the larger in Kr. principal quantum number electron spin momentum and as atomic radius increases. OLi, B, C, BC, O Question 23 (1 point) Arrange the following elements in order of increasing effective nuclear charge: Al, Si, P. Na, Mg Be, B, C, N, F OC, N, O, Li, Be OS. P. Si, Al, Mg
