At present there are more than 50 elements in the world. There are 92 natural and 115 total when we add the synthetic elements.
There are 118 known chemical elements as of 2011.
All of them. There are no elements lighter than hydrogen. It has only two atomic particles, and you cannot have an element with less.
Iodine represents less than 0.01 percent of body weight.
No, xenon is less reactive than iodine. Xenon is a noble gas and is known for its inert and stable nature, while iodine is a halogen and is more reactive, especially towards other elements.
115 known chemical elements. However, that number is not accurate; there are really more than that now.
As far as we know, there are much less than a million. All of the known elements in the world are listed on the Periodic Table of Elements.
There are 118 known chemical elements as of 2011.
it bonds with many elements but it is less reactive than the rest of the halogens
There are 92 natural elements, but there are more than 100 elements if included synthetic ones.
Metals are a group of elements on the periodic table known for their conductivity, luster, and malleability. They are not the most known elements, but they are widely used in a variety of applications due to their unique properties. The most known elements are likely oxygen, hydrogen, carbon, and nitrogen due to their abundance and importance in the natural world.
These would be ions.
Trace elements.
Most elements can have more than one oxidation number, but I think you are looking for the transition elements in groups 3 - 12.
Yes, in the same sense that there are 99 elements and 10 elements. MORE than 100 elements are known.
Infinite
7 of them.
well i think its 32
