The horizontal rows on the Periodic Chart are called Periods.
The vertical columns on the are called Groups, or sometimes Families.
The only nonmetal to the left of the zigzag line in the periodic table is hydrogen (H). It is positioned above group 1 on the periodic table because it shares some chemical properties with the alkali metals, but it is not a metal.
In the periodic table metals are on the left of the line. But elements touching it are called semi metals and have properties of both metals and nonmetals
Metalloids bridge between the metals on the left and the nonmetals on the right.
The periodic table is arranged from left to right in the order of atomic numbers.
The reactivity generally decreases as you move from left to right across the periodic table. This is because elements on the right side tend to have more electrons in their outer shell, making them less likely to form bonds with other elements.
The only nonmetal to the left of the zigzag line in the periodic table is hydrogen (H). It is positioned above group 1 on the periodic table because it shares some chemical properties with the alkali metals, but it is not a metal.
The left to right rows on the periodic table are called periods. Each period represents the energy levels of the elements, with the elements in the same period having the same number of electron shells.
In the periodic table metals are on the left of the line. But elements touching it are called semi metals and have properties of both metals and nonmetals
Metalloids bridge between the metals on the left and the nonmetals on the right.
The horizontal rows are referred as periods. There are 7 periods in periodic table.
The periodic table is arranged from left to right in the order of atomic numbers.
All three join operations work in a similar manner, with the difference being the rows that are returned. A left join and right join are also commonly called "semi-joins." Both operate in the same manner, with the difference being which table is the primary table. In a left join, all rows on the left-hand table that meet the criteria are returned, even if there is no matching right-hand table data for that row. A right join is the complementary version of a left join; all rows on the right-hand table are returned, even if there is no left-hand table data. A full join returns all matching rows, even if there is no data on either the left-hand table or the right-hand table.
The reactivity generally decreases as you move from left to right across the periodic table. This is because elements on the right side tend to have more electrons in their outer shell, making them less likely to form bonds with other elements.
The horizontal rows on the periodic table are called periods.
This row of chemical elements is a "period".
There seems to be a typo in your question. If you meant a "horizontal row" (left to right) of the periodic table, those are called periods. If you meant a "vertical column" (up and down) of the periodic table, those are called groups.
Across a period, as we move from left to right, the electronegativity increases in the periodic table.
