You should know that they are divalent elements, as they have two electrons in their outermost energy levels . The word “metal” arises from metallon,with which the Greeks described the mining … Metals are ductile (can be stretched into thin wires). Most metals are electropositive in nature and the metal atoms lose electrons in chemical reactions to form cations. The second group of elements in the Periodic table is Alkaline Earth metals. most are hard and shiny, less reactive, examples are iron, copper, nickel and gold. Alkali metals are very reactive. alkaline earth metals. Metals can usually be oxidized easily. Francium is not extracted from the Earth's crust. Metals are lustrous, malleable, ductile, good conductors of heat and electricity. hard, grey-white, good conductors of electricity, calcium and magnesium are examples. All metals conduct electricity. 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. Nov 7, 2007 . 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 CHEM. Mixed metals. Found along the 'staircase'. Alkaline-earth metals: Alkaline-earth metals are the second group on the periodic table.

Among the best known properties are good conductors of heat, sound and electricity at room temperature and at atmospheric pressure. least reactive, examples are tin, lead and aluminum. The elements can be broadly divided into metals, nonmetals, and semi metals. the first period below the periodic table, they are mixed with more common metals to form alloys . Your Response. Metals occupy the bulk of the periodic table. That's to be general. They have a gray-white lustre when freshly cut but tarnish readily in air, particularly the heavier members of the group. On the periodic table they can be located to the left of, but not touching, the heavy, stair-step line. ? Other properties include: State: Metals are solids at room temperature with the exception of mercury, which is liquid at room temperature (Gallium is liquid on hot days). We have step-by-step solutions for your textbooks written by Bartleby experts! Being a metal, they are obviously good conductors of heat and electricity. The vast majority of the known elements are metals. Properties of Non-Metals Non-metals are poor conductors of heat and electricity. Short Answer:For all practical purposes, any metal will be both a good conductor of electricity and a good conductor of heat. Best ones are: Silver, copper, tin, lead. Graphite (a form of carbon) is a rare example of a non-metal that conducts electricity very well. The majority of elements in the periodic table are metals. The alkaline-earth elements are highly metallic and are good conductors of electricity. Have properties of both metals and nonmetals. Other properties include: State: Metals are solids at room temperature with the exception of mercury, which is liquid at room temperature (Gallium is liquid on hot days). nonmetals . alkaline earth metals. It is very important to know that the alkaline earth metals are located on the left side of the periodic table , They are the second group of s-block after group ( 1 A ). mixed metals. The alkali metals are softer than most other metals.Cesium and francium are the most reactive elements in this group.Alkali metals can explode if they are exposed to water. Alkali metals Alkaline Earth Metals Boron Family Carbon Family Nitrogen Family Oxygen Family Halogen Family Noble Gases 0 0 249; liz. They are malleable, ductile, and usually solid at room temperature. most are hard and shiny, less reactive, examples are iron, copper, nickel and gold. Physical Properties of Metals. Lanthanides. Respond to this Question. Nov 6, 2007 . 14. lanthanides. MORE INFO The elements are beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), and radium (Ra). They begin on the left side and extend across the periodic table. Textbook solution for World of Chemistry, 3rd edition 3rd Edition Steven S. Zumdahl Chapter 8 Problem 28A. Noble gases ? Yes, but alkali and alkaline earth metals have less conductance. Alkaline earth metals. The properties of metals are those qualities that are attributed to metals . Look up noble gases. Most have high boiling point. It is used exclusively only for pure research. hard, grey-white, good conductors of electricity, calcium and magnesium are examples. by rahul Are all types of metals good conductors? Alkali metals have an oxidation state of +1 and are good conductors of heat and electricity. Halogens ? Both have metallic properties: conduct heat and electricity; malleable/ductile etc. Mass Number. They also tend to be shiny and bendable – like copper wire. alkaline earth metals. Semi metals exhibit properties intermediate between those of metals and nonmetals. The number of protons in the nucleus of an atom of an element. Gr1 metals are soft and very reactive. Non-metals have a variety of properties, but very few are good conductors of electricity. transition metals. Metals are malleable (can be pounded into thin sheets). Transition metals. (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. least reactive, examples are tin, lead and aluminum. Metals are good conductors of electricity because the free electrons can move around freely within the metal. lanthanides. Alkali metals ? Alkaline earth metal – Transition metal - Metals are elements that are good conductors of electric current and heat. The more reactive a metal, the greater tendency it has to form a positive ion in a chemical reaction. Exist as diatomic molecules Relatively low melting points and densities Have properties between metals and nonmetals Good conductors of heat and electricity Dull, brittle, and poor conductors lanthanides. Alkali earth metals have the capability to lose the two electrons in their outer shell. Metals and non-metals. Similar Questions. metalloids. least reactive, examples are tin, lead and aluminum. 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. They are malleable, ductile, are good conductors of heat and electricity and are softer than most metals. Beryllium is sufficiently hard to scratch glass, but barium is only slightly harder than lead. This group includes the elements Lithium, Sodium, Potassium, Rubidium, Cesium, and Francium. ALL metals are good conductors of heat. the first period below the periodic table, they are mixed with more common metals to form alloys . and the non-metals. They are good but not as the alkali and alkaline earth metals. Compared to other elements they have a low melting and boiling point. Transition metals. Most have high melting point. For example: How are metals arranged in a periodic table? Francium is a unstable, radioactive metal with a maximum half–life of only 22 minute. It is very important to know that the alkaline earth metals are good conductors of the heat and the electricity . Alkaline-earth metal, any of the six chemical elements that comprise Group 2 of the periodic table.
