What are the 3 main groups of metal?

Answer 1

54 of our chemical elements are classed as metals. All metals share certain properties such as being ductile (capable of being deformed or stretched), malleable (easily bent or shaped) and a conductor of heat and electricity. The metals are divided into different groups depending on their other properties. An element's properties are a result of how many electrons are in its outer energy level and position on the Periodic Table is based on this. This means each group of elements that share similar properties occupies a specific area on the periodic table. The metal groups are alkali metals, alkaline earth metals, transition metals and other metals. The alkali metals and the alkaline earth metals, groups one and two respectively on the periodic table, have similar properties. Due to their high reactivity they are not found in their pure forms naturally. The elements that make up the alkali metals are lithium, sodium, potassium, rubidium, caesium and francium. They all have only one electron in the outer energy level, meaning they behave similarly in the formation of compounds. Alkali metals react violently with water. For instance, if potassium is dropped in water it floats around while emitting a violet flame. Groups one metals are relatively soft, with low densities and melting points compared to other metals. The alkaline earth metals form group two of the periodic table, so each have two electrons in their outer shell. These are beryllium, magnesium, calcium, strontium, barium and radium. They have similar properties to the Alkali metals in group one. Group two metals, when compared to group one metals on the same period (row) of the periodic table, show some consistent differences. The group two metals are less reactive than those in group one. For instance calcium can react only with hot water, whereas potassium, its group one counterpart, reacts violently with any water. The group two metals have higher melting and boiling points and are harder, stronger and denser. The transition metals lie in the centre block of the periodic table, in groups 3 to 12. There are 38 transition metals, including elements such as iron, gold and zinc. Transition metals share some common characteristics. The majority are a silvery-blue colour at room temperature (copper and gold being the exceptions to this.) Many form coloured compounds, and many are good catalysts. They have high densities and melting points. The three magnetic elements iron, cobalt and nickel are all transition metals. The final group is the "other metals", or "poor metals" located in groups 13, 14 and 15. This includes aluminium, gallium, indium, tin, thallium, lead and bismuth. They are softer than transition metals, with lower melting and boiling points.

Answer 2

The three main groups of metal are ferrous metals (containing iron), non-ferrous metals (not containing iron), and precious metals (rare and highly valuable metals like gold and silver). Each group has its own unique properties and uses in various industries.

Answer 3

There are no "2 main groups" There are 3 (some consider them 4) The first are the ALKALINE METALS these are the most reactive of all. They are soft, and react vigorously in even cold water. They include sodium, caesium and francium(francium is also radioactive). These do not appear to be shiny as a layer of oxide forms around it, giving it a rather dull texture. However, if you cut through a lump of sodium with a knife (which can be done due to softness, but be CAREFUL or it will blow up in your face) it will be as shiny as any other metal. They conduct heat and electricity well. The next are the GROUP 2 METALS these are quite reactive, but not as much as group 1. They are slightly stable and react well with oxygen when heated. These are also slightly harder than group 1 metals and are much more chemically stable. E.g. magnesium. They conduct heat and electricity well. The TRANSITION METALS, these are found in the centre block of the periodic table, which are also known as the "strong metals" almost all of them are colourful in solution, e.g. Copper sulphate (aq) is a brilliant blue colour. They are more stable and include a wide variety of different metals: Iron, Cobalt, Mercury, Gold, Silver, Manganese. They conduct heat and electricity well. Can be stretched and hammered into shape (ductile & malleable) Now, these are classified as SEMI-METALS, POOR METALS or METALOIDS they posess properties of both metals & non-metals. Some conduct heat and electricity well, while some are insulators. Some can be stretched and hammered into shape (ductile & malleable), whilst others are brittle. I hope you find this useful

Answer 4

group 1=Alkali (metal)

Group 2= alkaline (metal)

Group 3-12=transitional metals (metal)

group 1,2,13-18= representative elements (s and p orbits)

group 17= halogens

group 18= nobel gas or inert gas

Answer 5

Alkali earthmetals.metalloids and non metals.

Answer 6

There are alkali metals (Group 1A), alkaline earth metals (Group 2A) and the transition metals (all the Group B metals).

Answer 7

Groups lA and llA but there are also other metals in the periodic table as bismuth which is found in group V A

Answer 8

The alkali metals, alkali earth metals, and transition metals.
