Atoms are the smallest particle of matter. Each has a nucleus of protons and neutrons surrounded by electrons.
An element is an atom with a particular atomic number, that is, a certain number of protons. Each element has a different number of protons.
A compound is something formed by two or more atoms.
Atoms elements is the small element that cannot be simplified. Compounds are chemical substances that are made up of two elements.
atoms combine to form molecules of elements
Simply because they exist in their natural state. Most elements are naturally found in compounds (ores, minerals) and must be processed to access the actual elements.
Yes that is possible. Mixtures can have two or more elements, two or more compounds, or both. For instance, you could have a mixture of noble gases or a mixture of two different elemental metals. The thing is that the elements have to be stable so that they would not react among themselves and form a compound.
the properties of an ionic compound can be explained by ht e strong attractions among ions within a crystal lattice.
Molecular compounds tend to have lower melting points.
the theory that development is directed by constraints inherent in the relationship among elements within the organism as they act upon themselves and each other.
atoms combine to form molecules of elements
No. It is exactly the opposite. Carbon forms many varied molecules, especially organic compounds with oxygen and hydrogen. The noble gases are the elements that form few compounds.

Molecular compounds tend to have lower melting points.
Noble gases are chemically inert, they do not form compounds. They are found in trace amounts and hence difficult to be identified.
