Water is not classified as an element because it is made up of two atoms of Hydrogen and one atom of Oxygen, both of which are elements. A combination of two or more atoms of elements are called compounds. Water is a compound, not an element.
MgCl2 is classified as ionic. It is a metal and a non metal.
Calcium is not a non-metal, it is an alkaline earth metal.
In the periodic table, it is classified as an alkali earth metal, so yes, it is a metal.
calcium is a metalloid as it stands between metal and non metal as it doesn't have all the porperties of metal. calcium oxide is not an element so neither metal or non metal it is a compound
Oxygen is classified as a non-metal element.
Neither. It is classified as a compound.
Neither. Nitrogen is classified as an element with no family designation.
Neon is neither a metal nor non-metal. it is a noble gas.
non metal
Elements are classified as metals, non-metals and metalloids and this classification is not for compounds. Iron sulfide is a compound, the question is non-applicable as it is neither a metal or a non-metal.
Sodium chloride is a compound, not a chemical element.
Bromine is classified as a non-metal. It is a member of the halogen group in the periodic table and typically exhibits non-metallic properties such as being a poor conductor of heat and electricity.
Carbon is a non metal.
Neither. It is classified as a compound.
MgCl2 is classified as ionic. It is a metal and a non metal.
No, it is a metal, as all the other actinides are.
Calcium is not a non-metal, it is an alkaline earth metal.
