Yes, according to Glencoe science gold is the most stretchable of any element on the Periodic Table of elements. In science the word 'ductile' is usually used in place of stretchable. The ability of a metal to be stretched would be called its ductility. This is in contrast to malleability, the ability of a metal to be hammered into thin layers. Gold is both highly ductile and highly malleable, but the characteristics do not always go together. Lead, for example, is highly malleable but not very ductile.
Graphene is considered one of the most elastic substances in the world. It is a two-dimensional material composed of a single layer of carbon atoms arranged in a hexagonal lattice structure, known for its exceptional strength, flexibility, and elasticity.
No, calcium (Ca) is not the most active element. The most active elements are typically found in Group 1 of the periodic table, such as sodium (Na) and potassium (K), which readily react with water and air.
No. Sulphur or if you must Sulfur is an element. It is not a mixture of any kind.
uranis has the most compounds
An element is a substance that has one kind of atom.

Sodium isn't any kind of compound. It is an element.
Radon (Rn) has the most protons of any element in Group 0 (18) with 86 protons. However, if or when Ununoctium is officially confirmed, that will become the element with most protons in that family, with 118 protons.
It kind of depends on what "these" sets are.
Carbon
I believe you are talking about subsets. The empty set (set with no elements) is a subset of any set, including of the empty set. ("If an object is an element of set A, then it is also an element of set B." Since no element is an element of set A, the statement is vacuously true.)
Lead isn't "made out of" any other metals. It's an element.
The most ideal fabric for a maternity swimsuit is Lycra as it stretches well for the expanding abdomen and yet retains its shape and provides support. Any other stretchable fabric will work as long as it is also supportive.
There is no "most important element" for corn. However, the nutrient which is most used up by the corn crop, and therefore costs the most for the the farmer to replace is nitrogen. No element is more important than any other because if any one nutrient, even a micronutrient, is completely missing, there will be no crop to harvest.
In chemistry, a compound molecule that is made of multiple elements is different from an element molecule. Other things that are not elements: Light, or any kind of electromagnetic radiation
An element can only change if the number of protons in its nucleus changes. It is possible to make one kind of element into another, but all these processes can be accomplished only by nuclear means. Gold can be changed into another element in a physics lab, but only with the use of a nuclear reactor or an accelerator of some kind. Any element can be changed into another element, but only by nuclear means.
