What is the difference between metals and metalloids?
Metals are the pure substances by and show only characteristic properties of metals while a metalloid is an element which show some properties of metals and some properties of non metals as Aluminium, Zinc and Tin.
Are alkali metals electro-positive?
Yes they are!even though they are very soft, reactive and not as widely used as much as transition metals eg. in construction they still have other metallic properties, such as metallic bonding.Yes all alkali metals are metals.
What are the metalloids?
Metalloid, or semi metal is a term used in chemistry when classifying the chemical elements. On the basis of their general physical and chemical properties, nearly every element in the periodic table can be termed either a metal or a nonmetal. However, a few elements with intermediate properties are referred to as metalloids. They are sometimes called (and confused with) semiconductors and semimetals. The following elements are generally considered metalloids: * Boron (B) * Silicon (Si) * Germanium (Ge) * Arsenic (As) * Antimony (Sb) * Tellurium (Te) * Polonium (Po) Inclusion of polonium is somewhat academic because all its isotopes are radioactive.
What metals cant be picked up by electromagnets?
Many metals cannot be picked up by electromagnets (at room temperature). For instance, aluminum, gold, mercury, and copper will not be attracted to an electromagnet. Iron sticks to an electromagnet at normal temperatures. If iron is too hot, it loses its magnetic abilities. This is true of all metals: if they're cold enough they exhibit magnetic properties, if they're too hot they don't show magnetic properties. Even mercury (liquid at room temperature) can be made magnetic if it's cooled to very low temperatures.
Is a metalloid a nonmetal?
Tree's are nonmetal, they are mainly made up of cellulose and water. Tree stems consist mainly of support and transport tissues xylem and phloem. Although they do have some metal compounds absorbed from the soil, they are negligible amounts. regards Mitch
What are elements that show moderate electrical conductivity?
Semiconductors are elements that show moderate electrical conductivity. Metalloids are elements that show properties of both metals and nonmetals.

Can you show me the periodic table?
By there properties: Metals, Non-Metals and Metalliods.
Element that has both properties of metals and nonmetals?
The elements that show properties of both metals and nonmetals are referred to as metalloids and include, boron, silicon, germanium, arsenic, polonium, tellurium, and antimony.
Do metals show chemical properties?
yes. for example, rust on iron and tarnish on silvers are both examples of oxidization.
Elements that show moderate electrical conductivity?
Semiconductors
Elements that have physical and chemical properties of both metals and nonmetals are known as?
there are no elements which show exact properties but... 1) Luster : Graphite and iodine 2) Liquid metals : Bromine, Mercury 3) Thermal conductivity : Diamond 4) Electric " " : Graphite 5) Non metals which are hard : Graphite and Diamond
What are the chemical and physical properties of nonmetals?
Non-metals are poor conductors, are brittle, not ductile in their solid state, show no metallic luster, and have low density.
Elements that lie along the stair-step line of the periodic table are?
Boron, Silicon, Arsenic, Tellurium, Astaline. This is also called the "Magic Stairs"

How can one show that elements that have different appearances have similar chemical properties?
You can experiement with the melting point, boiling point, and freezing point of the elements to prove they have similar properties. This and you can check the different physical and other chemical properties for similarities and comparison.
