Periodic Table Worksheet



Periodic Table WorksheetWhere are the most chemically reactive metals located?The Alkali Metals in group 1Where are the most chemically reactive nonmetals located?The Halogens in group 17Elements in Group 1 are called.The Alkali MetalsElements in Group 2 are called.The Alkaline Earth MetalsElements in Groups 3-12 are called.The Transition MetalsAs you go from left to right across the periodic table, the elements go from (metals/nonmetals) to (metals/nonmetals).Metals to NonmetalsGroup 17 elements are called.The HalogensThe most chemically reactive element in Group 17 is.FluorineGroup 18 are called the . Why this name?The Noble Gases because they do not react.The majority of the elements in the periodic table are (metals/nonmetals).MetalsElements in the periodic table are arranged according to their.Atomic Number (number of protons)What element is in Group 4, Period 5?ZirconiumWhat element is in Group 13, Period 2?BoronWhat element is in Group 17, Period 3?ChlorineHow many elements are in Period 4?18How many elements are in Period 6?32What is the mass of the halogen in Period 2?19 amu (fluorine)How many metals are in Group 14?2 (tin and lead)How many valence electrons does oxygen have? 6How many valence electrons does lithium have? 1How many valence electrons does iodine have? 7How many electrons does a neutral atom of oxygen have? How many valence electrons?8 total electrons. 6 valence electronsHow many electrons does a neutral atom of potassium have? How many valence electrons?19 total electrons. 1 valence electronHow many neutrons does the alkaline earth metal in Period 4 have?20 (calcium)How many gaseous elements are there?10 (nitrogen, oxygen, fluorine, chlorine, and the 6 noble gases)How many elements exist in the liquid state at room temperature?2 (mercury, bromine) Why are groups sometimes called families?Groups are called families because elements in a group share many physical and chemical propertiesHow many energy levels (“shells”) does oxygen have?2What does chemical reactivity mean? Which part of the atom is responsible for an element’s reactivity? Chemical reactivity is the likelihood that an element will combine with another element in a chemical reaction. The valence electrons are responsible for an element’s reactivity. ................
