They are malleable, ductile, are good conductors of heat and electricity and are softer than most metals. Mass Number. On the periodic table they can be located to the left of, but not touching, the heavy, stair-step line. Metals are good conductors of electricity because the free electrons can move around freely within the metal. The second group of elements in the Periodic table is Alkaline Earth metals. Transition metals. Some of the groups have widely-used common names, including the alkali metals (Group 1) and the alkaline earth metals (Group 2) on the far left, and the halogens (Group 17) and the noble gases (Group 18) on the far right. It just so happens that some conduct more that others, but since you asked for it, here they are: Actinide Metals, Lanthanide Metals, Alkali Metals, Alkaline-Earth Metals, Noble Metals, Rare Metals, Rare-Earth Metals, and Transition Metals. MORE INFO Short Answer:For all practical purposes, any metal will be both a good conductor of electricity and a good conductor of heat. Similar Questions. The more reactive a metal, the greater tendency it has to form a positive ion in a chemical reaction. Metals are good conductors of heat and electricity. Look up noble gases. least reactive, examples are tin, lead and aluminum. 14. Metals—such as copper or gold—are good conductors of electricity and heat; they can be pulled into wires because they are ductile; they can be hammered or pressed into thin sheets or foils because they are malleable; and most have a shiny appearance, so they are lustrous. ALKALINE EARTH METALS • show metallic properties Be being the least metallic • good conductors of heat & electricity • Mg most used as metal • Be - rare & costly • Ca, Sr, Ba - too reactive • Ra - radioactive specie. Alkali metals ? Properties of Metals Metals are good conductors of heat and electricity. Yes, but alkali and alkaline earth metals have less conductance. chemistry. lanthanides. They also tend to be shiny and bendable – like copper wire. Metals occupy the bulk of the periodic table. Alkaline-earth metal, any of the six chemical elements that comprise Group 2 of the periodic table. Halogens ? Group 2: Alkaline Earth Metals. The general electronic configuration of Group 2 elements is ns 2. As with all metals, the alkali metals are malleable, ductile, and are good conductors of heat and electricity. Among the best known properties are good conductors of heat, sound and electricity at room temperature and at atmospheric pressure. Non-metals are … Metals are ductile (can be stretched into thin wires). Transition metals. metalloids. Physical Properties of Metals. most are hard and shiny, less reactive, examples are iron, copper, nickel and gold. That's to be general. The Transition Metals Groups 3 through 12 include 38 elements called transition metals. All metals conduct electricity. Metals are good electrical and heat conductors. This group includes the elements Lithium, Sodium, Potassium, Rubidium, Cesium, and Francium. Alkali metals have an oxidation state of +1 and are good conductors of heat and electricity. The majority of elements in the periodic table are metals. least reactive, examples are tin, lead and aluminum. Select all true statements from the following: a. ) most are hard and shiny, less reactive, examples are iron, copper, nickel and gold. actinides . A chemical property of metal is its reaction with water which results in corrosion. Metals are shiny. and the non-metals. They begin on the left side and extend across the periodic table. the first period below the periodic table, they are mixed with more common metals to form alloys. Metals like iron (Fe), copper (Cu), aluminum (Al) and gold (Ag) are often used in electronic cables and electrical circuits because of their electrical conductivity. (see exception below) This is probably because the electrons in the hot environment gain kinetic energy and can easily move from atom to atom - thereby moving the kinetic energy around. Francium is not extracted from the Earth's crust. Noble gases ? The periodic table contains four kinds of metals: alkali metals, alkaline earth metals, transition metals, and post-transition metals. nonmetals . 0 0; DrBob222.

Alkali earth metals have the capability to lose the two electrons in their outer shell. Compared to other elements they have a low melting and boiling point. There are many divisions in the Periodic Table, but one of the most important is between the metals. transition metals. Most metals are electropositive in nature and the metal atoms lose electrons in chemical reactions to form cations. Respond to this Question. Metals are lustrous, malleable, ductile, good conductors of heat and electricity. brittle , dull, poor conductors of heat and electricity. Let’s take some examples to understand the reactions of such metals. They are metallic elements and have an oxidation number of +2, making them very reactive. alkaline earth metals.
