AQA Chemistry Group 1 (Alkali Metals) 3.0 / 5 based on 1 rating ? ChemistryChemical patterns and reactivity seriesGCSEAQA Created by: BenjaminCreated on: 01-04-13 14:25 Name the first 6 Alkali Metals Lithium, Sodium, Potassium, rubidium, Caesium, Francium 1 of 16 Are the alkali metals non-reactive? NO THEYRE VVVERY REACTIVE 2 of 16 Why do group 1 metals have to be stored in oil? to stop them from reacting with O2 in the air 3 of 16 As you go down group 1, what happens to the reactivity of the elements? Increases 4 of 16 Name the most/least reactive alkali metal Lithium=least reactive Francium=Most reactive 5 of 16 What can we say about the density of the alkali metals compared to other metals That they are very dense in comparison 6 of 16 State a property of the alkali metals, besides their density They're soft 7 of 16 How many electrons do group 1 elements have on their outer shell? 1 8 of 16 The 1 electron on the outer shell, is a similarity shared by all of the alkali metals. It gives them all _________ _________ Similar Properties 9 of 16 As they only need to lose one electron to get to a stable (Noble gas) structure, are the alkali metals very reactive? YES! 10 of 16 When group 1 elements react with ____ - Metals, what do they lose? Their 1 outer electron 11 of 16 When group 1 elements react with non metals, what sort of ions do they form, and what charge is left on their ions They form Metal ions, with a 1+ charge as they give away their 1 outer electron 12 of 16 What do group 1 metals always form when they react with non-metals Ionic compounds 13 of 16 Whats the formula for a lithium/sodium/Francium Ions? Li+ Na+ Fr+ (All have a +1 charge) 14 of 16 As you go down group 1, do melting/boiling points get higher or lower? Decrease 15 of 16 When metals x,p and y are added to water, they fizz and float around. Name elements x, p and y Lithium, Sodium and Potassium 16 of 16
