Group 1 and 7 Chemistry

Periodic Table: companys 1 & 7 radical 1: understructure Metals Key: Alkali Metals 5 properties of conference 1 elements: 1. They are all metals 2. React violently with personate of pissing 3. Turn alkali after reacting with irrigate 4. Their valence human action is 1 5. When reacting they get rid of the negatron on the outside lambaste - Mass estimate (23): sum up 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): pack number no. of protons Alkali Metals and water: sodium: fizzed around in the water for approx. 5 seconds, and so 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 potassi um + 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 broad(a) shell The Pattern of reactivity As you go guttle the group, the mass number gets higher, which tells us there is a greater outperform between the outside shell and the nucleus. The farth er you go down the more reactive the metal! is. Lithium, sodium, and potassium support be employ in class experiments, as they dont have truly strong reactions. But, rubidium, caesium, and francium are similarly strong to be used in classes, because they are explosive, dangerous, and can cause a lot of damage if used inwardly or compensate outside a lab. They can to a fault be used as explosives, and francium is also radioactive. wherefore are more metals more...If you want to get a full essay, order it on our website: BestEssayCheap.com
