Very few elements exist in their free state in nature. The vast majority of them exist as compounds, chemically bonded to other elements.
They are gases that do not form normal chemical bonds with more than a very few other elements.
No, elements become less metallic across periods. Periods are horizontal rows within the periodic table, and read left to right. The far right elements are called non-metals, and the far left elements are called metals. In between these two groups are a few metalloids - elements that have characteristics of both metals and non-metals. A period looks like this: Metals --> Metalloid --> Non-metals
FALSE. There are probably 15 elements more dense than mercury. A few examples would be Osmium, Platinum, and Gold, just to name a few.
Yes, far more. The typical tornado is a few hundred feet across. The typical hurricane is a few hundred miles across.
There are many elements less electronegative than silcon. Look at the periodic table, and pretty much everything (with a few exceptions) to the left of, and below silicon will be less electronegative.

There are more metals than nonmetals on the periodic table. There are 18 nonmetals, compared to 117 known elements.
There are some elements that are larger than Uranium in atomic size that occur naturally, however these are few and far between, and are usually very rare elements. Some synthetic elements can be created using an Atomic Collider, but when this happens, the atoms, which are almost certainly very radioactive and very unstable, will expire before proper studies can be made, due to a half life of >1 second.
a chemical combination of a few elements. n.c101
I am not sure what you mean by 'non elements'.ALL matter is made up of elements - there is no such thing as a 'non element'.Elements can however join up to form compounds and the number of compounds that can be formed far exceeds the number of elements that comprise them.
The expression is 'few and far between'. His visits are few and far between.
They are gases that do not form normal chemical bonds with more than a very few other elements.
because they have outer electrons than can merge with other elements. all elements want to have full outer electron shells, and they only have a few outer electrons.

The saying is "few and far between". The "far between" part refers to distance. The phrase "few between" doesn't make much sense.
