Why is lead calasified as a metal?

Answer 1

From Wikipedia: In chemistry, a metal (Greek: Metallo, Μέταλλο) is an element, compound, or alloy characterized by high electrical conductivity. In a metal, atoms readily lose electrons to form positive ions (cations); those ions are surrounded by delocalized electrons, which are responsible for the conductivity. The thus produced solid is held by electrostatic interactions between the ions and the electron cloud, which are called metallic bonds. From me:

If an element shows these characteristics, it is a metal. Calcium shows these characteristics. Therefore, Calcium is a metal.

Answer 2

It is a metallic element due to the overlap between the conduction and valence bands. This occurs because of the splitting of the 4s and 4p energy levels creates an overlap of available states. Therefore, there are available (unoccupied) energy states for the electrons to be thermally excited into, thus creating a metal.

Answer 3

metal calcium is all about how young female leopards can be, some are even as young as mary the bear. although calcium is dangerous many believers belive that it is vital to stay away from it because it can effect your age hormone. this is doubtfull but can occur once approached by an old wrinkly man. even such things as eating you rmeals 3 times a day can prevent flu, this is very useful for metal calciuum as it makes you behave in a sensitive way making sure that you feed and men on the way to school.

Answer 4

Because it has the physical and chemical properties of metals, such as it is ductile and a good conductor of heat and electricity.

Answer 5

It is a compound that is not metallic. This mineral is a common antacid.

Answer 6

Calcium is an element and a metal.

Answer 7

No. calcium is a metal.
