Reading the Periodic Table An element’s square has the element’s symbol and name, atomic number and mass, and electron configuration. The elements are grouped into alkali metals, alkaline earth metals, and halogens.
Using Reference Table S, Complete the tables below for the Group 2 Alkali Earth metals.. Once done, scale, plot and graph the data on the graphing grids to observe trends of the four properties.
4 lut 2021 · Group 1: the Alkali Metals The elements in Group 1 of the periodic table o all have 1 electron in their highest energy level o are metals with low density (the first three elements in the Group are less dense than water) o are stored under oil to prevent them from reacting with oxygen or water. Increasing Reactivity down the Group
