Can you list 4 properties of metals?
1. Most are solid at room temperature except for Mercury
2. They are generally malleable and ductile
3. They are generally good conductors of heat and electricity
4. They generally form positive ions.
Can you list 4 properties of nonmetals?
1. They rarely have metallic luster.
2. They are usually gases at room temperature.
3. Nonmetallic solids are neither malleable nor ductile.
4. They are poor conductors of heat and electricity
They are all in the same group (column) of the Periodic Table and have the same number of valence electrons (4).
Antoine Lavoisier, a French chemist, classified the known 33 elements into four categories based on their properties in the late 18th century. The four categories were metals, non-metals, earths, and gases. This classification system laid the foundation for the periodic table that we use today.
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
All you have to do is look on your periodic table of elements. Metals are to the left and non-metals are to the right. This way we know group four are metals.
Yes, 3 or 4 times as many elements are metallic. Note, the whole left AND bottom portions of the Periodic Table are metals.
The differences between metal and non-metals are their chemical properties. Metals usually have 1-3 electrons on their outer shells, and non metals have 4-8 electrons in their outer shells.

What are the properties of metals and non-metals? basically :Properties of Metals; *Tensıle strength , *shear strength , *compressıve strength , *ductility,*malleability, *toughness,*corrosion , *electric and thermal conductivity, *brittleness. *Luster * Conductivityand you asked non metals but you have to decide what kind of material what you asked there are 6 main kind of matter like ceramics , composites , carbons , metals&alloys , polymers...=== ===
There are a number of ways in which a metal can be differientiate a metal from a non-metals, these involve contrasting the properties between metals and non-metals and testing them to distinguish them from one another. Some contrasting properties between metals and non-metals: 1.) Metals conduct electricity whereas non-metals do not. 2.) Metals are shiny whereas non-metals are not. 3.) Metals are malleable whereas non-metals are brittle. 4.) Metals often have a higher boiling/melting point than non-metals. 4.) Metals are hard whereas non metals are not.
They are all in the same group (column) of the Periodic Table and have the same number of valence electrons (4).
1. they are not good conductors of heat and electricity(except graphite) 2.they are not malleable (cannot be hammered into sheets). 3.they are not ductile(cannot be drawn into wires). 3.they have low densities.

Non-metals have 4, 5, 6, 7, and 8 valence electrons, respectively.
magnesium is not a metal but a reactive metal. scientists have divided all elements into two types of category: metals and non-metals to classify them as they have different chemical and physical properties. magnesium has properties of a metal so it is a metal.
Yes, 3 or 4 times as many elements are metallic. Note, the whole left AND bottom portions of the Periodic Table are metals.
