Section 5.2: Electron Configuration and the Periodic Table Periods and Blocks of the Periodic Table: Elements arranged vertically in groups/family with similar properties Elements in horizontal rows (period) w/ similar chemical properties Length of period = number of electrons occupying sublevels being filled in that period Periodic Table divided into 4 blocks: s,p,d,f Name of each block determined by whether an s,p,d, or f sublevel is being filled in successive elements of that block Period of element determined from element?s electron configuration Aresnic: [Ar]3d104s24p3 4 in 4p3 indicates arsenic?s highest occupied energy level is 4 The s-Block Elements: Groups 1 and 2: Elements of s block are chemically reactive metals (Grp1 more reactive)

Define the following terms: Stable- Not likely to change or fail; firmly established Unstable- Prone to change, fail, or give way; not stable Radioactive Decay- The process in which a radioactive nucleus emits (gives off) radiation and changes to a different isotope or element. A number of different particles can be emitted by decay. The most typical are alpha, beta particles, and gamma rays. Radio Isotope- The process in which a radioactive nucleus emits (gives off) radiation and changes to a different isotope or element. A number of different particles can be emitted by decay. The most typical are alpha, beta particles, and gamma rays. Daughter Element- an element that results from the radioactive decay of another element.
