Like the alkali metals, the alkaline earth metals are so reactive that they are never found in elemental form in nature.

# data[].attributes.body
Its Hardness is slightly superior to alkali, have free movement of electrons, so it is conductive

# data[].attributes.body
1.Non-metal
2.inactive

# data[].attributes.body
The Alkaline Earth Metals are metals that have two valence election.

# data[].attributes.body
1.non-metal
2.Conductive：  can
malleable：can‘t
reactive：  can't
3.CO2      CO       C       C60
4.The Carbon is a chemical element with symbol C and atomic number 6.

# data[].attributes.body
1. It is metals
2. At room temperature for weak conductor, and electricity well in high temperature. It is very brittle. It is reactive.
3.Include elements: boron (B);Aluminum (Al);Gallium (Ga);Indium (In);Thallium (Tl)

# data[].attributes.body
F,Cl,Br,l,At all together called halogens.

# data[].attributes.body
1.non-metal.
2.conductive.
3.CO2 CO
4.At room temperature,CO2 and CO are gas. They are harmful to our health.They are all non-metal and they are conductive

# data[].attributes.body
The halogens is non-metal

The halogens is reactive

The halogens are a group in the periodic table consisting of five chemically related elements: fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and astatine (At)

# data[].attributes.body
1. Oxygen, sulfur and selenium are nonmetals.
Tellurium and polonium are metalloids.
2. It is reactive.

# data[].attributes.body
Lithium conducts electricity and is used for batteries.

# data[].attributes.body
Because they only have one valence electron, they are very reactive and usually are in compounds.

# data[].attributes.body
The Alkali Metals are metals that have one valence electron.
