Alkaline earth metals are elements present in the second group of the periodic table. True or false

True

Explanation:

Alkaline earth metals are found in the second group on the periodic table. They are made up of elements:

 Beryllium

 Magnesium

 Calcium

 Strontium

 Barium

  Radium

These elements have two valence electrons in their outer most shell. Together with group one elements they are s-block elements.

answer:

the answer is 6 valence electrons.

explanation:

valence is the # of electrons on the outer most shell of an atom.

oxygen has 6.

although, the valency of oxygen is 2, because it only needs to make 2 covalent bonds, or gain 2 electrons, to achieve the stable octet configuration of a noble gas.

that's it!
