Nonmetal oxidesreact with water to produce what are known as oxo-acids or oxyacids, i.e. acids containing NM-O-H unit, where NM = nonmetal. A non metal oxideis usually characterized by polar covalent bondsrather than the ionic bonds of a metal oxide.
27/2/2012· 1.B 2.D 3.A 4(a)Only an element can be classified as a metal or non-metal. Water is not an element. 4(b)Non-metal.It is dull in appearance and low density although it is a electrical conductor. 4(c)Metal,it has high density and it is a electrical conductor 5(a)Mercury.
The sulfides, antimonides, arsenides, selenides, tellurides, and sulfosalts may be grouped according to the ratio of metal to nonmetal contained in their chemical formulae. Let the letter A represent a metal or a semimetal acting as a ion, while X represents a nonmetal or a semimetal acting as an anion.

Metals form ionic compounds with non-metal elements. For example in fluorite or calcium fluoride CaF 2 , calcium is metal and fluorine is non-metal. Types of metals Of the 118 elements of the periodic table, 91 are metals. We can classify them into four general
23/7/2018· For example, graphite and diamond are two allotropes of the nonmetal carbon, while ferrite and austenite are two allotropes of iron. While nonmetals may have an allotrope that appears metallic, all of the allotropes of metals look like what we think of as a metal (lustrous, shiny).
We can refer to the periodic table and classify each compound or solution as follows: (a) CaO contains two elements, a metal and nonmetal. Thus, CaO is a binary ionic compound. (b) SO 2 contains two elements, both nonmetals. Thus, SO 2 is a . (c) Ag 2 CrO

In a blast furnace, iron is extracted from its ore hematite. The substances added in the blast furnace which undergo reaction are hematite, coke and limestone. The coke, which is primarily carbon
Using the periodic table, classify each of the following elements as a metal or a nonmetal, and then further classify each as a main-group (representative) element, transition metal, or inner transition metal: (a) cobalt (b) europium (c) iodine (d) indium (e) lithium
The characteristic properties of metals and nonmetals are quite distinct, as shown in the table below. Metalloids, straddling the metal-nonmetal border, are mostly distinct from either, but in a few properties resele one or the other, as shown in the shading of the metalloid column below and summarized in the small table at the top of this section.
In chemistry, a nonmetal (or non-metal) is a chemical element that mostly lacks the characteristics of a metal.Physically, a nonmetal tends to have a relatively low melting point, boiling point, and density.A nonmetal is typically brittle when solid and usually has poor …
