02-01-2022· That means there are total 7 periods in periodic table. Now, you can see that there are only 2 elements in the 1st period. Thus, period 1 is known as shortest period. Now, the 2nd period and 3rd period has 8 elements, so period 2 and period 3 are known as short period. 4th and 5th period has total 18 elements.
Dividing line between metals and nonmetals - Wikipedia
References to a dividing line between metals and nonmetals appear in the literature as far back as at least 1869. In 1891, Walker published a periodic 'tabulation' with a diagonal straight line drawn between the metals and the nonmetals. In 1906, Alexander Smithpublished a periodic table with a zigzag line separating the nonmetals from the rest of elements, in his highly influential textbook Introduction to General Inorganic Chemistry. In 1923, Horace G. Deming, an America…
