inactive having;having few or no active chemical properties
An atom. Anything smaller is an atomic particle from which all elements are made.An atom is the smallest particle of an element that has properties of that element.An atom is the smallest unit of an element that retains the properties of that element.
If the substance is an element the answer is an atom. If the substance is a compound the answer is a molecule.
Because they have similar chemical properties. The reason they have similar chemical properties is because they have the same number of valence electrons. The differences are caused by them having different masses and because the larger elements have their valence electrons "screened" more from the nucleus by electrons in lower energy levels.
Dobereiner is remembered for what were called "Dobereiner's Triads" which are groups of three elements having similar chemical properties. This is a forerunner of the periodic table, but it is not actually a table, and it does not offer any explanation for the chemical similarities observed within the triads. Mendeleev's Periodic Table of the Elements shows the relationship of every element to every other element, and explains why they all have the chemical properties that they have.

Inert
Enzymes
Yes, Mt.Shasta is still active, having last erupted 200 years ago.
An atom is simply the smallest component of an element having the chemical properties of the element. An aluminum atom, is simply that, the smallest part of aluminum having the chemical properties of aluminum.
What is the question exactly? If it is about Uranium having physical and/or chemical properties, the answer is that it has both. Every single element and compound in this universe has both physical and chemical properties.
Group are based on similar properties. The elements having same chemical properties are grouped together.

Mass gets preserved (you have to consider the stuff that isn't the end produced chemical, too). Otherwise, chemical changes are known for having different properties. They could have similar properties, I imagine, but then, "Why would anybody want to make them?"

The smallest particle of matter having distinctive chemical and physiacl properties; a tiny particle
Medicine means a chemical that is suposed to help you get better.
