- Hydrogen. H.
- Helium. He.
- Lithium. Li.
- Beryllium. Be.

- Nitrogen. N.

What is 9 on the periodic table?
It is a member of the chalcogen group on the periodic table, a highly reactive nonmetal, and an oxidizing agent that readily forms oxides with most elements as well as with other compounds. By mass, oxygen is the third-most abundant element in the universe, after hydrogen and helium.
What is period 5 on the periodic table?
The fifth period contains 18 elements, beginning with rubidium and ending with xenon. As a rule, period 5 elements fill their 5s shells first, then their 4d, and 5p shells, in that order; however, there are exceptions, such as rhodium .
What is the zigzag line in the periodic table called?
Metalloids - are found along the zigzag line on the periodic table.
What is called the vertical line of periodic table?
Answer: In the Mendeleev periodic table, the vertical columns are called groups and the horizontal rows are called periods. Mendeleev claimed the famous periodic law that “Element properties are a periodic function of their atomic weight.”
What is a row in a periodic table?
A period in the periodic table is a row of chemical elements. All elements in a row have the same number of electron shells.
What call the horizontal rows?
periodThe horizontal rows are called period and the vertical columns are called groups.
Who published the periodic table?
In 1906, Alexander Smith published 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 American chemist, published short ( Mendeleev style) and medium ( 18-column) form periodic tables.
When was the dividing line between metals and nonmetals first used?
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 Smith published a periodic table with a zigzag line separating the nonmetals from the rest ...
What is a double line?
Double line variant. A dividing line between metals and nonmetals is sometimes replaced by two dividing lines. One line separates metals and metalloids; the other metalloids and nonmetals.
What did Hinrichs write about the periodic table?
In his article Hinrichs included a periodic table, organized by atomic weight, but this did not show a metal-nonmetal dividing line. Rather, he wrote that, '... elements of like properties or their compounds of like properties, form groups bounded by simple lines. Thus a line drawn through C, As, Te, separates the elements, having metallic lustre from those not having such lustre. The gaseous elements form a small group by themselves, the condensible [sic] chlorine forming the boundary ... So also the boundary lines for other properties may be drawn.'
What is the line between groups 13 and 14?
It is also erroneously referred to as the Zintl border or the Zintl line. The last two terms instead refer to a vertical line sometimes drawn between groups 13 and 14. This particular line was named by Laves in 1941. 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.
What elements are considered metalloids?
Elements commonly recognised as metalloids (boron, silicon, germanium, arsenic, antimony and tellurium) and those inconsistently recognised as such (polonium and astatine) Metal-nonmetal dividing line (arbitrary): between Li and H, Be and B, Al and Si, Ge and As, Sb and Te, Po and At, Ts and Og. v.
When was Deming's table published?
Merck and Company prepared a handout form of Deming's 18-column table, in 1928, which was widely circulated in American schools. By the 1930s Deming's table was appearing in handbooks and encyclopaedias of chemistry. It was also distributed for many years by the Sargent-Welch Scientific Company.
