The alkali metals are shiny, soft, highly reactive metals at standard temperature and pressure. 3.1.6: Deduction of the electron configuration of an atom from the element’s position on the periodic table, and vice versa. You can tell what suborbital an element has by looking at the block that it is in, and how many electrons there are by looking at the period that it is in. Four elements P, Q, R and S belong to the third period of the Modern Periodic Table and have respectively 1, 3, 5 and 7 electrons in their outermost shells. Write the electronic configurations of Q and R and determine their valences.

Most tables list element symbol I don't know guys, I feel like they might have missed a few. This post deserves a WTF just for good measure.

A new row begins when chemical properties repeat. The periodic table codifies the energy levels in periods, the rows on the table. The simplest atoms, hydrogen and helium, are found in row 1, or the first period. These atoms have electrons occupying the energy level n=1. Moving down, row 2, or period 2, contains the elements Li (lithium) through Ne (neon). Interactive periodic table with up-to-date element property data collected from authoritative sources.
