Respond to this Question. hard, grey-white, good conductors of electricity, calcium and magnesium are examples. Metals can usually be oxidized easily. 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. chemistry. most are hard and shiny, less reactive, examples are iron, copper, nickel and gold. Good conductors of heat. Good conductors of electricity, shiny in colour, highly reactive with water and are stored under oil. React with water, forming hydrogen gas and basic solution (alkaline solution) Highly reactive with Alkali metals and Alkaline Earth Metals-react to form salts. (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. Atomic Number. Most metals are electropositive in nature and the metal atoms lose electrons in chemical reactions to form cations. most are hard and shiny, less reactive, examples are iron, copper, nickel and gold. Transition metals. The number of protons in the nucleus of an atom of an element. hard, grey-white, good conductors of electricity, calcium and magnesium are examples. First Name. Non-metals have a variety of properties, but very few are good conductors of electricity. Your Response. 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. The properties of metals are those qualities that are attributed to metals . Metals occupy the bulk of the periodic table. Metals are ductile (can be stretched into thin wires). Metals are shiny. Textbook solution for World of Chemistry, 3rd edition 3rd Edition Steven S. Zumdahl Chapter 8 Problem 28A. The alkaline-earth elements are highly metallic and are good conductors of electricity. least reactive, examples are tin, lead and aluminum. 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. Best ones are: Silver, copper, tin, lead. Groups 3-12. transition metals. alkaline earth metals. ALL metals are good conductors of heat. Properties of Metals Metals are good conductors of heat and electricity. metalloids. The elements are beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), and radium (Ra). 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. 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 Transition metals. Alkali metals are very reactive. most are hard and shiny, less reactive, examples are iron, copper, nickel and gold. Alkali earth metals have the capability to lose the two electrons in their outer shell. Graphite (a form of carbon) is a rare example of a non-metal that conducts electricity very well. they're metals, to be precise gr1 alkaline gr2 alkaline earth. Yes, but alkali and alkaline earth metals have less conductance. Most have high melting point. Look up noble gases. by rahul Are all types of metals good conductors? Alkaline Metals Group 2 includes the alkaline earth elements. alkaline earth metals. The general electronic configuration of Group 2 elements is ns 2. Short Answer:For all practical purposes, any metal will be both a good conductor of electricity and a good conductor of heat. alkaline earth metals. 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. Metals are good conductors of heat and electricity. That's to be general. Francium is not extracted from the Earth's crust. It is used exclusively only for pure research. 14.

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. Alkaline-earth metal - Alkaline-earth metal - Physical and chemical behaviour: The alkaline-earth elements are highly metallic and are good conductors of electricity. On the periodic table they can be located to the left of, but not touching, the heavy, stair-step line. Francium is a unstable, radioactive metal with a maximum half–life of only 22 minute. The periodic table contains four kinds of metals: alkali metals, alkaline earth metals, transition metals, and post-transition metals. They are metallic elements and have an oxidation number of +2, making them very reactive. Alkali Metals Properties of Alkali Metals: They are all soft, shiny, malleable, ductile, good conductors of heat and electricity , react vigorously with water and they have one electron in the highest (outermost )energy level. hard, grey-white, good conductors of electricity, calcium and magnesium are examples. A tiny, negatively charged particle that moves around the nucleus of an atom. The Transition Metals Groups 3 through 12 include 38 elements called transition metals. There are many divisions in the Periodic Table, but one of the most important is between the metals. the first period below the periodic table, they are mixed with more common metals to form alloys. Non-metals are … Thus, they react with other elements and form ionic compounds. transition metals. The more reactive a metal, the greater tendency it has to form a positive ion in a chemical reaction. Have properties of both metals and nonmetals.
