Are there about 5 thousand elements which combine to form the vast number of different substances in the world around us?
No, there are not about 5,000 elements which combine to form the various substances in our world; there are actually 102 elements which do so. Aside from those 102 elements, about a dozen super-heavy elements have also been synthesized, but they have very short half lives and their atoms don't stick around very long.Even those 102 elements include some with very short half lives, so there are really only about 90 elements that we find in the world around us. Many elements have several stable or unstable isotopes, which vary by the number of neutrons in the atomic nucleus.
If A and B are disjoint sets and A contains 5 elements and B contains 7 how many elements are in the union of A and B?
