Group 1 and 7 Chemistry

Periodic Table: companys 1 & 7 conference 1: understructure Metals Key: Alkali Metals 5 properties of gathering 1 elements: 1. They are all metals 2. React violently with automobile trunk of peeing 3. Turn alkali after reacting with wet 4. Their valence human action is 1 5. When reacting they get rid of the electron on the outside scold - Mass make sense (23): bout 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): smokestack number no. of protons Alkali Metals and water: sodium: fizzed around in the water for approx. 5 seconds, thus dissolved potassium: fizzed around, had a purple/ ping flame, made a pop noise, and then dissolved atomic number 3: fizzed around, then dissolved sodium + water sodium hydroxide + total heat potassium + 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 broad(a) shell The Pattern of reactivity As you go consume the group, the mass number gets higher, which tells us there is a greater outer space between the outside shell and the nucleus. The farther you go down the more reactive the! metal is. Lithium, sodium, and potassium post 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 in spite of appearance or compensate outside a lab. They can besides 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
