in the periodic table the elements that are adjacent to the stair step are called
Dividing line between metals and nonmetals This line has been called the amphoteric line,[2] the metal-nonmetal line,[3] the metalloid line,[4][5] the semimetal line,[6] or the staircase.[2][n 1] It is also erroneously[citation needed] referred to as the Zintl border[8] or the Zintl line.[9][10] The last two terms instead refer to a vertical line sometimes drawn between groups 13 and 14. This particular line was christened by Laves in 1941.[11] It differentiates group 13 elements from those in and to the right of group 14. The former generally combine with electropositive metals to make intermetallic compounds whereas the latter usually form salt-like compounds.[12]

Periodic table The periodic table is a useful tabular arrangement of the chemical elements, ordered by their atomic number, electron configuration, and recurring chemical properties, whose adopted structure shows periodic trends. Generally, within one row (period) the elements are metals on the left, and non-metals on the right, with the elements having similar chemical behaviours being placed in the same column. Table rows are commonly called periods and columns are called groups. Six groups have accepted names as well as assigned numbers: for example, group 17 elements are halogens; and group 18 are noble gases. Also displayed are four simple rectangular areas or blocks associated with some approximately similar chemical properties.
