An alloy is a fusion of two or more types of metals, to create a new one. Such as titanium.

Metals give up electrons while non-metals gain electrons
Most metals react with acids to give off hydrogen. Only very nonreactive metals, like gold and platinum do not react with metals. An example would be: Calcium + Hydrochloric Acid = Calcium chloride + Hydrogen gas (Ca +2 HCl = CaCl2 + H2)
Metals that have a density greater than the density of water will sink in water, while metals that have a density less than water will float. For example, metals like lead, gold, and silver will sink in water, while metals like aluminum and lithium will float.
Example sentence - The metals in the ore had to be separated.
Metals are used in medicine for diagnostic purposes. One example of this is cobalt. Metals can also be toxic. Metals such as mercury and copper can be harmful.

when recovering metals from ores
Alkali metals are lithium, sodium, potassium, rubidium, caesium and francium.They are the metals with the higher chemical reactivity.
Ferrous metals are those contain iron. All ferrous metals are magnetic and give little resistance to corrosion.
== == When metals react with other elements, the atoms of the metals give up their valence electrons.
