Dmitri Mendeleev developed a chartlike arrangement of the elements called the

. He stated that if

the elements were listed in order of increasing 5, their properties repeated in a regular manner. He called

this the

of the elements. The arrangement used today differs from that of Mendeleev in that the

elements are arranged in order of increasing 6. Each horizontal row of elements is called a(n) 16. Each

vertical column is called a(n) 9, or , because of the resemblance between elements in the same column,

a(n) 8.

In rows 4 through 7, there is a wide central section containing elements, each of which is called a(n) 20.

Rows 6 and 7 also contain two other sets of elements that are listed below the main chart. These are

called the

and the 11, respectively. Each of the elements to the left of the stairstep line of the chart, is

classified as a(n) 12. Each of the elements at the right side of the stairstep line is classified as a(n) 15.

Each of the elements between these two main types, having some properties like one type and other

properties like the other type, is called a(n)13. Each of the elements in the column labeled IA or 1 is

called a(n) 2. Each of the elements in the column labeled IIA or 2 is called a(n) 3. Each of the elements in

column VIIA or 17 is called a(n) 10. Each of the elements in column VIIIA or 0 or 18 is called a(n) 14.
