There are many. Number 43 (technetium) and numbers 84-118 are also made in laboratories. However, numbers 90, 91 and 92 are found in nature but they're also made in laboratories. They are made by throwing different atoms in each other. For example, ununoctium was made by throwing californium atoms in calcium atoms.
ductility is a property of a solid, and since hydrogen doesn't form a solid under natural or even laboratory conditions, it doesn't apply
Dew does not form damp and wet conditions.
The wet and cold weather conditions.
By "seeing" under water.

Yes
Yes, Some elements that have been made by scientists under laboratory.
Substance that cannot be changed into a simpler substance under normal laboratory conditions are elements. A physical blend of two or more substances that are not chemically combined is a mixture.
Helium, Neon, and Argon are the most non-reactive elements known. Though it is possible to make them react with other elements, it is extremely difficult and can only be achieved under precise laboratory conditions.
tell whether each fraction is in simplest form. if not, write it in simplest form, tell whether each fraction is in simplest form. if not, write it in simplest form,
A statement that describes what scientists expect to happen every time under a particular set of conditions is a scientific law. A scientific law always applies under the same conditions, no matter what the elements are.
salmonella is one.
Under standard laboratory conditions, calcium is a solid.
Non-metal? Water would be one.

No, because some scientists work outdoors....but on the other hand they might. This is because some scientists have to take indoors what they find and examine it under laboratory type tools.
