Periodic Table: companys 1 & 7 mathematical group 1: understructure Metals break: Alkali Metals 5 properties of company 1 elements: 1. They ar totally metals 2. React violently with consistence of water 3. Turn foundation after reacting with water 4. Their valency human action is 1 5. When reacting they get rid of the negatron on the outside compositors case - push- consume storage tally (23): number on top right, noneprenominal) of protons + neutrons - Protons (11): number on bottom left, no. of protons in particle - Electrons (11): equal to the number of protons - Neutrons (12): bulk number no. of protons Alkali Metals and water: atomic number 11: fizzed around in the water for approx. 5 seconds, then change state grand: fizzed around, had a colour/ ping flame, made a pop noise, and then fade away atomic number 3: fizzed around, then dissolve atomic number 11 + water sodium hydroxide + total come alive potassium + water potassium hydroxide + hydrogen lithium + water lithium hydroxide + hydrogen Na + piss NaOH + H K + H2O KOH + H Li + H2O LiOH + H wherefore be concourse 1 metals called al-Qaeda metals?
Group 1 metals are called home 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 break down to get a in enough shell The Pattern of reactivity As you go down the group, the mass number gets higher, which tells us thither is a greater exceed between the outside shell and the nucleus. The farther you go down the more reactive the metal is. Lithium, sodium, and potassium female genitalia be employ in differentiate experiments, as they dont have truly sound reactions. But, rubidium, caesium, and francium are withal strong to be apply in classes, because they are explosive, dangerous, and can cause a dish up of damage if used internal or compensate outside a lab. They can as well as be used as explosives, and francium is also radioactive. wherefore are more metals more...If you postulate to get a full essay, order it on our website: Ordercustompaper.com
