metal, metalloid, and non-metal. Metals are everything left of the stair-step line, metalloids are MOST of the metals along the stair-step line, and non-metals are everything to the right of that line. The stair-step line is a line that goes (in a stair-like fashion) from between Al and B to between Po and At.

Were are the lanthanides placed on the periodic table?
The lanthanides are a series of elements that are placed at the bottom of the periodic table. They are located in the f-block, specifically in the period below the main body of the periodic table. The lanthanides have atomic numbers 57-71.
Which element family is usually shown separated frome the main part of the periodic table?
f block elements (lanthanides and actinides) are placed below the periodic table
What main blocks of elements is Cr in?

How do the two main classifications of matter differ?
The two main classifications of matter are pure substances and mixtures. Pure substances are made up of only one type of substance with specific chemical properties, while mixtures are made up of two or more substances physically combined with variable composition and properties.
What were the two main themes that mendeleev developed while writing his textbook the principles of chemistry?
Dmitri Mendeleev's two main themes in his textbook "The Principles of Chemistry" were the periodic law and the organization of elements into the periodic table based on their atomic weights. He also emphasized the relationships between the properties of elements and their positions in the periodic table.

What are the three main classifications of elements on the periodic table of element?
The three main classifications of elements on the periodic table are metals, nonmetals, and metalloids. Metals are typically shiny, good conductors of heat and electricity, and malleable. Nonmetals are usually dull in appearance, poor conductors of heat and electricity, and brittle. Metalloids have properties that are intermediate between metals and nonmetals.
