Uses/Found in:Cu, Copper- wiring, Zn, Zinc – sunblock, Au, Gold – Astronaut helmets Family Number: 3-12 Group Number: NO group numbers Number of valence electrons: - Physical Properties: hard, malleable, ductile, good conductors Chemical Properties: Forms oxides and chlorides Reactivity: Low States of Matter: Solids except Mercury Bonds Well With: - Color: LIGHT BLUE Elemental Family Members: Be, Mg, Ca, Sr, Ba, Ra Uses/Found in: Ca –bones, Sr –red color in fireworks, Ba,green color in fireworks, Color: LIGHT REDġ1 Transition Metals Elemental Family Members: Family Number: 3-12Ģ1 (Scandium) through 29 (Copper) 39 (Yttrium) through 47 (Silver) 57 (Lanthanum) through 79 (Gold) 89 (Actinium) and all higher numbers. Reactivity: HIGH, but not as high as Alkali Metals States of Matter: Solids Bonds Well With: Halogens, giving 2 VE to one halogen each OR Oxygen Family give both VE away. Group Number: 2 Number of valence electrons: 2 Physical Properties: Silvery, soft, malleable, ductile, good conductors Chemical Properties: Wants to lose their 2 VE. Reactivity: HIGH States of Matter: Solids Bonds Well With: Halogens Elemental Family Members: Li, Na, K, Rb, Cs, Fr Uses/Found in: Li – batteries, Na – salt, K –found in bananas, Color: Lime Green Color: LIME GREENĩ Alkaline Earth Metals Color: LIGHT RED Family Number: 2 Reactivity increases as you move down the group. Number of valence electrons: 1 Physical Properties: Silvery, soft, malleable, ductile, good conductors Chemical Properties: Wants to lose their 1 VE. Note: It may look like the bottom two are in their own periods, but they are not! They are in periods 6 and 7.ħ Alkali Metals Color: Lime Green Family Number: 1 Group Number: 1 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.
