Dimitri Mendeleev developed a chartlike arrangement of the elements called the _____(1)______. He stated that if the elements were listed in order of increasing ______(2)______, their properties repeated in a regular manner. He called this the ______(3)______ of the elements. The arrangement used today differs from that of Mendeleev in that the elements are arranged in order of increasing _____(4)______. Each horizontal row of elements is called a(n)_____(5)______. Each vertical column is called a(n)______(6)______, or, because of the resemblance between elements in the same column, a(n) _____(7)______.
In rows 4 through 7, there is a wide central section containing elements, each of which is called a(n) _____(8)_____. Rows 6 and 7 also contain two other sets of elements that are listed below the main chart. These are called the ______(9)______ and the _____(10)_____, respectively. Each of these elements, as well as those in the first two columns at the left end of the chart, is classified as a(n)_____(11)_____. Each of the elements at the right side of the chart is classified as a(n) ______(12)______. Each of the elements between these two main types of elements, having some properties in common with each, is called a(n) ______(13)______.
Each of the elements in the column labeled 1 is called a(n) _____(14)______. Each of the elements in the column labeled 2 is called a(n) ______(15)_____. Each of the elements in column 17 is called a(n)______(16)______. Each of the elements in column 18 is called a(n)_____(17)______.
