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.
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.
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.
Metalloids are found approximately in the middle between the metals on the left and non-metals on the right.
Metals share properties such as: malleability, conductivity, strength and hardness. The reason properties of metals are different is because of metallic bonding. metals are made up of positively charged metal ions in a sea of delocalised electrons. This gives them the properties listed above. Ionic and molecular compounds are bonded in different ways. e.d ionic compounds are bonded in a rigid structure so it is brittle and non conductive
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.
the number of electrons in the outer shell .. for metals its less than 4 .. for non metals its more than 4 .. for semi its 4
Non-metals have 4, 5, 6, 7, and 8 valence electrons, respectively.
There are 4 non-metals in the third period of the periodic table (Phosphorous, sulfur, chlorine, and argon)
1.Non-metals are mostly liquids or gases but some are found in solid state.2.Non-metals are usually non-flexible.3.It is difficult to to mold non-meats and convert them into wires and sheets.4.In non-metals atoms are bonded by covalent bonds.5.Non-metals are usually non-conductors but few of them conduct electricity.6.Non-metals are easy to cut or break.7.Non-metals do not transfer heat.8.Non-metals do not have much brightness even on polishing.9.Non-metals do not absorb light.10.Non metals are usually light in weight and have low density.11.Non-metals usually have low melting and boiling points.12.Non-metals ion bear negative charge but some bear positive charge as well e.g.Hydrogen.13.Oxides of Non-metals are acidic.14.Non-metals have tendency to accept electrons.15.Non-metals do not react with water at room temperature.16.Non-metals rarely react with acids

Good question. They can actually do both. The metals and non-metals in the LEFT of the table is -1, -2. -3. -4.. From -4, they can either be -4, or +4. On the RIGHT it goes form +4+3+2+1
