WebNov 2, 2024 · The periodic table is a tabular arrangement of chemical elements that is arranged by increasing atomic number and groups elements according to recurring properties. The seven rows of the periodic table are called periods. The rows are arranged so that metals are on the left side of the table and nonmetals are on the right side. WebNov 23, 2024 · In period it increases from left to right until it has maximum 5 or 6 unpaired electrons (such as in period 4, chromium), then it decreases going further down to the right till it has 1 unpaired electron (such as in period 4, silver). Transition metal compounds can also show paramagnetic nature if it contains unpaired electrons. Colored compounds
