Start studying GCSE Chemistry - Year 9 - Year 10 (Group 0 - Transition Metals). They are very hard and strong and are good conductors of heat and electricity. When these transition metal ions react with a species, organic or inorganic, capable of donating a pair of electrons, a coordinate bond is formed between the metal ion and the electron donating species. aqa gcse 9-1 chemistry: Be able to compare the properties of Group 1 metals with transition metals Know the transition elements are metals with similar properties which are different from those of the elements in Group 1 alkali metals. They are malleable (can be hammered into shapes), sonorous (make a 'ringing' sound when struck with a hard object), and ductile (can be drawn out into wires) LO: Compare the properties of transition metals with those of Group 1 metals. This video explains more about Transition metals They have high density. Chance of getting into a good university due to bad GCSEs and UCAS doubt. Low density - can float on water. However, they are also considered as transition metals because they have similar properties to those of transition metals. Id honestly know how much you have to know for GCSEs as in my time, we only had to know this much. Iron, copper, silver and gold are important transition metals. The transition metals do not all have the same number of electrons in their outer shell, and so they have different valencies, forming 1 +, 2 +, or 3 + ions with non-metals. I assume you are referring to the fact that transition metals have similar chemical properties just like how elements in other 'groups' (alkali, alkaline earth, halogens) have similar chemical properties. Thanks! Our tips from experts and exam survivors will help you through. Gervald F. Lv 7. Favourite answer. This means they are more reactive. Chemistry 9-1 GCSE equations and formulae. The table shows some examples of these. The transition metals are placed in the centre of the periodic table, between groups 2 and 3. Like other transition metals, iron forms coloured compounds. They are generally hard and dense, and less reactive than the alkali metals. Anonymous. Made for AQA 2016 GCSE, but can be used with any exam board. ion. How can this be an advantage?
