![]() ![]() ![]() Period 1 has 1 shell, Period 2 has 2 shells, Period 3 has 3 shells, and so on. Each Period tells us how many electron shells the elements in the row has. Ex) Group 1 (Alkali Metal Family) bonds well with Group 7 (Halogens) to achieve 8 total valence electrons.Ħ Periods of the PTE There are 7 periods on the PTE.Ītomic Number of each element increases as you move across the PTE. Elements in each group are looking to bond with other elements to achieve the Happy Number of 8 valence electrons. Elements in each group have similar properties with other elements in that group. Elements in each group are grouped into families based on chemical properties.Ĭhemical properties would include how reactive they are. We do not count the Transition Metal family when dealing with valence electrons, we skip over that family (they have a whole different set of rules when bonding). Group 1 has 1 valence electron, Group 2 has 2 valence electrons, Group 3 has 3 valence electrons, and so on. ![]() Groups, like families, are found in columns. However, when counting how many valence electrons each family has, we call them Groups. Columns run up and down (vertical).Ĥ Groups of the PTE: Groups and Families are the same thing. The largest family is the Transition Metal Family. Presentation on theme: "Color Coding the Periodic Table of Elements"- Presentation transcript:ġ Color Coding the Periodic Table of ElementsĢ We are about to get started on the Lesson…ģ Families of the PTE: There are 18 families on the PTE.Įach family has a specific name.
