Ask Question + 100. Use the periodic table to give the name and symbol for the alkaline earth metal in the same period with the neutral noble gas with 18 electrons. Halogens on the Right In the second column from the right side of the periodic table, you will find Group Seventeen (Group XVII).This column is the home of the halogen family of elements. This is only two electrons away from having a full octet of eight electrons, so many of these elements form anions having -2 charges: oxide, O 2-; sulfide, S 2-, selenide, Se 2-, etc. Join Yahoo Answers and … the halogen in the same period as lithium; the chalcogen in the same period as cadmium; Use the periodic table to give the name and symbol for each of the following elements: the halogen in the same period as the alkali metal with 11 protons; the alkaline earth metal in the same period with the neutral noble gas with 18 electrons Lv 7. my.chemeurope.com. The name halogen is derived from the Greek words for “salt forming,” which reflects that all the halogens react readily with metals to form compounds, such as sodium chloride and calcium chloride (used in some areas as road salt).
