4th Grade Science Term Project Name: _Alejandro Mejia ________________________ ____________14/05/2015______ Date: Research 3 elements of your choice and fill in the chart below Li Element Name & Symbol Atomic Structure (drawing) F Al *Include correct number of shells, protons, neutrons and electrons.* (towards IM1) What kind of bonds does your element prefer and why? (Ionic or covalent) *Think about number of shells, electrons and charges.* Lithium fluoride LIF Magnesium fluorine MF2 Magnesium aluminum MG2F3 Covalent Ionic Ionic Find a common element that your element bonds with. Draw your element and the new element and explain how they bond. Lithium Fluorine give a proton to lithium to form lithium fluoride or liF Fluorine give a proton to lithium to form lithium fluoride or liF NO3AL is that this 3 elements give 3 protons to aluminum to make NO3AL Lithium oxide It is a compound already between magnesium oxide and hydrogen flouride Sodium aluminum fluoride *Think about number of electrons on each element’s outer shell.* (towards IM2) Name a compound, mixture and/or solution that your element makes.

Earth Earth Earth What do people in Colombia or other countries use this element for? C1 Production of uranium, Air conditioning, Refrigeration, Insecticide, Toothpaste, Added to municipal water supplies, Teflon Lithium batteries Lithium orotate, carbonate, polymer & bromide Lithium ion battery a basic metal or as an alloy for utensils, engineering, electrical equipment, cooking foil, and canning; where lightness, cheapness, tensile strength or conductivity are factors in design. World Nutrition Global Health What do you consider will be the role of chemistry in the future in terms of… C2 Global water supply Lithium: the toothpaste is made with lithium so it waste water Fluorine: is made to do batteries and that is toxic for water animals Aluminum: it is used to cook and cooking need water Lithium: is a toxic element so if you eat it you die Fluorine is used for batteries and that can help to not contaminate the world and use that batteries for cooking Lithium: it is a toxic element so that can damage the health Fluorine is used to do a liquid to make batteries but that is toxic. Aluminum is used for Aluminum is a metal making tools for eating like but it can be bad for a fork or a knife. the digestion
