Review earlier notes and complete the table below for the given elements based on their electron configuration. The order of filling electrons is: 1s 2s 2p 3s 3p 4s 3d 4p 5s 4d 5p 6s 4f 5d 6p 7s 5f 6d 7p (s-2, p = 6, d = 10 and f=14 is total electron holding capacity for each sublevel) -The block type is the letter of the sub-level in which last electron goes when writing electron configuration -The period number is the highest level number, and the total of all electrons in the highest level represents the number of valence electrons for that element - Group number can be determined from the ending of electron configuration: s1 Group 1_ 52 group 2 For "d" block elements: group # = 2+ number of electrons in last "d" sublevel For "p" block elements, group # = 12 + number of electrons in last "p" sublevel For "f" block elements, group # is 3

Match the quantum numbers associated with each of the following orbitals: 4p Choose... 1s Choose... = 6d Choose... 5f Choose... (

Use spdf and noble gas notations to give the electron configurations of these two elements. (Express your answer as a series of orbitals. For example, the electron configuration of Li would be entered in complete form as 1s 2 2s ¹ or in condensed form as [He]2s ¹.) spdf notation configuration for the element 113: Noble gas notation configuration for the element 113: spdf notation configuration for the element 115: Noble gas notation configuration for the element 115: For each of these elements, name another element in the same periodic group. Another element for the element 113 is Another element for the element 115 is Element 113 was made by firing the nucleus of a light atom at a heavy americium atom. The two nuclei combine to give a nucleus with 113 protons. What light atom was used as a projectile?
