Group 1 and group 2 elements are reactive metals and react readily with water. They also react readily at high temperatures with oxygen. Over the millenia any free deposits would react to form compounds.

Is sodium a lipid?
No, sodium is a highly reactive metal that does not occur free in nature. Lipids are a type of carbon compounds (e.g. fats, cholesterol).
Which of the following groups in the periodic table contain elements so reactive that they are never found in the free state?
group 1 and 2
Why are Alkaline metals not found free in nature?
because they are extremely reactive. They belongs to group of one periodic table and have one electron in the outer valence shell.
How does magnesium occur naturally?
Magnesium is very abundant in nature, occurring in substantial amounts in many rock-forming minerals such as dolomite, magnesite, olivine, and serpentine. In addition, magnesium is also found in sea water, subterranean brines, and salt beds.
Why is hydrogen written alone on the periodic table?
Hydrogen is not exactly written alone on the periodic table. The table is organized into rows and columns, both of which represent groupings of elements for different reasons. For example, elements in the same column (called "groups") all have the same number of free electrons, or "valence electrons". Elements in the same row have the same or similar numbers of filled electron shells. Hydrogen is in the top row because it has only 1 electron shell and it is in the far left column because it has 1 free electron (just like all of the elements beneath it). Helium, on the other hand, also has 1 electron shell, but is in the far right column because it has a full electron shell (no free electrons). This makes it chemically similar to all of the elements beneath it (this group is called the "noble gases" because they have no free electrons to interact with other elements).
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.
Does bromine occur as a liquid in nature?
Bromine is a liquid but doesn't occur in nature as a free element.
Is bromine an element that occur in nature as liquids?
Bromine is a liquid but doesn't occur in nature as a free element.
Does alkali metals occur freely in nature?
Compounds, or minerals. The most common is the sodium chloride found in sea water. They are too reactive to be found as free elements.
Which two elements occur in a nature as liquid?
Only mercury is a chemical element which occur in the nature as a liquid.
What groups of elements is most likely to contain elements that will be found free in nature?
The noble gases.
Which metals are not very reactive and occur in a free state in nature?
GoldPlatinum
Why is that some metals occur in nature as free elements while others occur in combine forms?
Depends on how easy it is to oxidize the metal, outside of gold and meteoric iron, almost all metals are found in an oxidized state.
Why are elements of group 1 alkali metals and group 7 halogens used as compounds and not as the free elements?
because god made it that way.
What is nature of Mercury?
Mercury do not occur in combine state (i.e. it occur in free state) and in liquid form. It is the only metal who occur in liquid form.
Why most elements not found in the free state in nature?
Most elements are sufficiently reactive so it can not exist in elemental form.
