All elements are made up of a single atom. This is the defining characteristic that makes it an element as opposed to a compound.
No, the other way 'round. An element exists at the single-atom level. A molecule is made of more than one atom. It can be a single element(hydrogen is more stable if 2 form a molecule H2), or can be hugely complex and made up of many different elements.
That's a difficult question to answer, because elements are made of atoms. An atom is the smallest particle of an element that has the properties of that element. Some elements, like the noble gases, can exist as single atoms. Other elements, like oxygen, exist as molecules, such as O2, which is composed of two oxygen atoms covalently bonded to one another. Metal elements are composed of many, many atoms joined by metallic bonding.
Atoms of elements have a fixed number of electrons that can bond with other atoms. Carbon has 4 electrons that can bond with other atoms. So 4 hydrogen atoms can bond with one carbon atom.
Maybe. A molecule is two or more atoms bonded together. Whilst you can have a molecule of only a single type of atom (ie: oxygen = O2) many other types consist of more than one type of atom (ie: NaCl = salt)
Though some molecules are made up from a single element, many of the molecules exist aren't from a single element.
We use atomic number for recognize chemical elements. atomic number means, how many protons are there in a single atom.

No. Elements are make up of only one type of atom, rocks are made up of many different elements.

An element is one single type of atom, oxygen is an element so are hydrogen and carbon. A tree is made of many elements put together, carbon, hydrogen, oxygen, nitrogen etc.
No, molecules and elements are not the same thing. An element is a pure substance made of only one type of atom, while a molecule is a group of atoms bonded together. Elements can exist as single atoms or as molecules depending on their chemical composition.
there are no atoms in a proton. a Proton is a part in the nuleus of an atom. the other parts of an atom are neutrons and electrons
One.
No. Iron is a single element. To be alive it would have to be made of many elements.
