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.
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, elements with very few valence electrons are typically non-metals. Non-metals tend to have higher electronegativities, making them more likely to gain electrons to achieve a stable electron configuration. Elements with few valence electrons are more likely to gain electrons rather than lose them, leading to non-metallic properties.
Yes, far more. The typical tornado is a few hundred feet across. The typical hurricane is a few hundred miles across.
According to the big bang hypothesis, hydrogen was the only element created after the big bang. Within the first few minutes, the temperature was hot enough for fusion to occur, enabling helium, lithium and a few other elements to be created. After about 3 minutes, the Universe cooled sufficiently, for this process to halt. It was not until about 500,000 million years later, when the first stars went supernova, that heavier elements were seeded into the Universe.

There are more metals than nonmetals on the periodic table. There are 18 nonmetals, compared to 117 known elements.
The expression is 'few and far between'. His visits are few and far between.
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 saying is "few and far between". The "far between" part refers to distance. The phrase "few between" doesn't make much sense.
for example, trees are few and far between in a large city. so it means that there are very few of somthing and they are far apart from eachother.
They are gases that do not form normal chemical bonds with more than a very few other elements.
Generally their damage paths are short, not more than a few miles, often less than a mile.
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.
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.
