chemical elements
The lowest chemical reactivity of all elements is the main chemical characteristic. An important physical characteristic is that they are all gases at standard temperature and pressure.
The most important principle was the listing in groups, after similar chemical or physical properties.
Chemical elements are combined to produce chemical compounds.

The most important is the electronegativity of chemical elements.
Metals nonmetals and metalliods
Chemical elements arrangement was the object of study for Mendeleev.
For chemical elements the most important factor is the electronegativity.
In chemistry it is very important to understand the properties of elements in order to predict their effects on other elements and compounds during chemical reactions. This information can be used to formulate a hypothesis for a reaction, or better understand the chemical processes that may have occurred in a reaction.
Electrons.

all matter is composed of atoms of chemical elements.
Blank is not a name for a chemical element.
Ga, Sc and Ge were important to Mendeleev because these three elements have the same physical and chemical properties.
