4th Grade Science Term Project Name: __samuel casallas ____________________ __________________ Date: Research 3 elements of your choice and fill in the chart below Element Name & Symbol O oxygen Cl chlorine N nitrogen Atomic Structure (drawing) *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.* Is covalent because is it not electricity conductor Is ionic because it is conductor of electricity Is covalent because is a conductor of electricity Find a common element that your element bonds with. Draw your element and the new element and explain how they bond. OXIGEN bond with carbon to do carbon dioxe Chlorine bond with sodium Nitrogen bond with to do sodium chlorine oxygen forms very much things but one is Dinitrogen trioxide *Think about number of electrons on each element’s outer shell.* (towards IM2) Name a compound, mixture and/or solution that your element makes. CT1 Carbon dioxide Is CO2 SODIUMCHLORINE (NaCl) Dinitrogen trioxide N203 Physical / Chemical properties of the element according to its place in the periodic table. CT2 This element is Physical This element is chemical this element is chemical In point form, list 3 other interesting facts about this element. #1 Oxygen is about two times more easy to dissolve in water than nitrogen is. #1 Sodium chloride is the most common compound of chlorine. #1 Nitrogen makes up around 78% of the air you breathe. Where in the universe will you find this element? #2 On the periodic table #2 Oxygen normally is Chlorine is in the halogen the molecule O2. group and it is the 2nd Ozone, O3 lightest halogen gas after fluorine. #3 Oxygen is the third #3 Chlorine (Cl2) is among most hearty element the ten highest volume in the universe. chemicals fabricated in the United States. Yes because is in all Yes because that use to parts ,is cover of clean the pools oxygen #2 yet air almost all is of nitrogen #3 Nitrogen is present in all living things, including the human body and plants. Yes to do experiments and saw colors What do people in Colombia or other countries use this element for? C1 What do you consider will be the role of chemistry in the future in terms of… C2 They breath the oxygen and do experiments with the oxygen Global water supply They can be better ,especially because h2o is water can be more easy to do better water to do better experiments and take better the water They use very much the cl(chlorine) in the pools World Nutrition Specially in the pools but they can change to do experiments with that of nutrition Specially to do experiments of what they can help us Global Health Can help to do a protector or something like that that can help to not do or smell the smoke of the factories
