No, right to left.
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.
Across a period, as we move from left to right, the electronegativity increases in the periodic table.
The periodic table is arranged by increasing atomic number, which moves from left to right across each row. As you move from left to right across a row, the elements increase in atomic number and atomic mass, with similar chemical properties grouped together.
When you move from left to right on the periodic table, the atomic number of the elements increase.
Electronegativity increases as we move from left to right on the periodic table.
The metalloids split the table these are a diagonal group of elements, B, Si, Ge, As, Sb and Te. To their right are the non metals to the left the metals. There are many more metals than any other type of element. See Wikipedia article "Periodic table (metals and non metals)"
They occupy all but the top right corner of the table.
Electronegativity increases from left to right and decreases from top to bottom on the periodic table.
Periods on the periodic table are the horizontal rows that go from left to right.
Nonmetals are located in the right corner of the periodic table of Mendeleev. See the link bellow for a periodic table. What? The nonmetals are located on the right of the periodic table, such as oxygen, nitrogen and chlorine.
