Did halogens frequently occur in nature as free elements?
Yes, the halogens did occur in nature as free elements.
What group of elements is most likely to contain elements that will be found free in nature?
The noble gases.
Why most elements not found in the free state in nature?
Most elements are sufficiently reactive so it can not exist in elemental form.
Is the far few materials are elements than are not elements?
Very few elements exist in their free state in nature. The vast majority of them exist as compounds, chemically bonded to other elements.
Why you cant find alkali earth metal free in nature?
because they are so reactive ,, we can find it in earth crust

Is the element platinum found free or is it chemically combined in nature?
Platinum usually exists uncombined in nature or alloyed with iridium.

Most elements are sufficiently reactive so it can not exist in elemental form.
Why do metals at the top of the activity series never found in the nature as free elements?
because they are too reactive to exist on their own, they bond with other elements in nature to satisfy their need for electrons
Is a metal free world possible?
There are metals and metallic elements in our bodies that we need, so no.

Very few elements exist in their free state in nature. The vast majority of them exist as compounds, chemically bonded to other elements.
Why is metallic sodium not found in nature?
Sodium is highly reactive and never exists in free state. It is always found in the combined state.
A reddish lustrous ductile mallable metal that occurs in nature in both free and combined states?
copper
Magnesium is not found naturally why?
Magnesium is an alkaline earth metal found in group 2 of the Periodic Table. That means it is fairly reactive and will readily combine with other elements or compounds rather than hang around by itself in nature.
Is calcium a substance?
Yes. Calcium is an element, and it has the atomic number 20 and Ca is its chemical symbol. It is a metal, and one of the alkali earth metals which are the elements in Group 2 of the periodic table. It is reactive, and as such is not found free in nature, but always appears in compounds with other elements. Wikipedia has additional information, and a link is provided.
