Group 1 and 7 Chemistry

Periodic Table: companys 1 & 7 concourse 1: understructure Metals Key: Alkali Metals 5 properties of convention 1 elements: 1. They are all metals 2. React violently with carcass of wet 3. Turn alkali after reacting with piddle 4. Their valence human action is 1 5. When reacting they get rid of the negatron on the outside squash - Mass act (23): bend on top right, no.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): aggregate number no. of protons Alkali Metals and peeing: sodium: fizzed around in the water for approx. 5 seconds, accordingly 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 potassium + water pot assium 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 bounteous shell The Pattern of reactivity As you go set down the group, the mass number gets higher, which tells us there is a greater remoteness between the outside shell and the nucleus. The farther you go dow n the more reactive the metal is. Lithium,! sodium, and potassium rear end 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 inner(a) or compensate outside a lab. They can likewise 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
