A - their physical properties (natural): - luster and sparkle. - A good conductor of heat and electricity. - High density. - High melting point. - Can be pulled to the wire. - Can tread the boards. - All solid except mercury liquid.
A - their physical properties (natural): characteristics unlike metals - do not shine without glitter. - Poor conductors of heat and Walkahraba, - fragile Taathishm easily. - Do not pull the slack. - Do not touched boards. - Low density. - A low melting point.
B - chemical properties: - tend to gain electrons and where the metals tend to lose electrons and Allamaadn tend to gain electrons. This metals and non-metals tend to form compounds of them. These compounds are called ionic compounds (ionized) ionic compounds. When you combine two or more of the compounds Allamaadn be united atoms a covalent compound. 3 - semi-metals (metals) Metalloids: have the properties of metals and Allamaadn.
