Group 1 and 7 Chemistry

Periodic Table: companys 1 & 7 gathering 1: understructure Metals Key: Alkali Metals 5 properties of group 1 elements: 1. They are all metals 2. React violently with personify of wet 3. Turn alkali after reacting with body of weewee 4. Their valency human action is 1 5. When reacting they get rid of the electron on the outside nonplus - Mass figure (23): lean on top right, zero(prenominal)prenominal) of protons + neutrons - Protons (11): number on bottom left, no. of protons in particle - Electrons (11): equal to the number of protons - Neutrons (12): loudness number no. of protons Alkali Metals and water: sodium: fizzed around in the water for approx. 5 seconds, therefore dissolved potassium: fizzed around, had a purple/ ping flame, made a pop noise, and then dissolved lithium: fizzed around, then dissolved sodium + water sodium hydroxide + total heat potas sium + water potassium hydroxide + hydrogen lithium + water lithium hydroxide + hydrogen Na + H2O NaOH + H K + H2O KOH + H Li + H2O LiOH + H thence are concourse 1 metals called alkali metals? Group 1 metals are called alkali metals because they become alkali when they react to water What happens to electrons when group 1 metals react? They release the electron on the out shell to get a bountiful shell The Pattern of reactivity As you go pile the group, the mass number gets higher, which tells us there is a greater outstrip between the outside shell and the nucleus. The farther you go down the more reactive the metal is. Lithium, sodium, and potassium stub be employ in class experiments, as they dont have truly strong reactions. But, rubidium, caesium, and francium are alike strong to be used in classes, because they are explosive, dangerous, and can cause a lot of damage if used inside or compensate outside a lab. They can excessive ly be used as explosives, and francium is al! so radioactive. wherefore are more metals more...If you want to get a full essay, order it on our website: BestEssayCheap.com
