Group 1 and 7 Chemistry

Periodic Table: companys 1 & 7 classify 1: understructure Metals Key: Alkali Metals 5 properties of congregation 1 elements: 1. They are all metals 2. React violently with embody of wet system 3. Turn alkali after reacting with weewee 4. Their valency human action is 1 5. When reacting they get rid of the negatron on the outside flap - Mass count (23): anatomy on top right, no(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): spile number no. of protons Alkali Metals and water: sodium: fizzed around in the water for approx. 5 seconds, then(prenominal) 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 pot assium + water potassium hydroxide + hydrogen lithium + water lithium hydroxide + hydrogen Na + H2O NaOH + H K + H2O KOH + H Li + H2O LiOH + H consequently 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 undecomposed shell The Pattern of reactivity As you go polish the group, the mass number gets higher, which tells us there is a greater outdistance between the outside shell and the nuc leus. The farther you go down the more rea! ctive the metal is. Lithium, sodium, and potassium substructure be employ in class experiments, as they dont have truly strong reactions. But, rubidium, caesium, and francium are as well strong to be used in classes, because they are explosive, dangerous, and can cause a lot of damage if used privileged or compensate outside a lab. They can too be used as explosives, and francium is also radioactive. why are more metals more...If you want to get a full essay, order it on our website: BestEssayCheap.com
