Metal because there the biggest section of elements on the periodic table true statement.
Because when you write the electron and orbital notations for elements, those are the elements that end in the p-orbitals.
Because in the table the elements are arranged into "periods", elements belonging to the same period have similar physical/chemical properties. This in tern reflects the fact that they have a similar number of outer shell electrons.
Mendeleev left blank spaces because certain elements on the Periodic Table were not known at that time. He knew that in the future, those elements would be found and placed on the periodic table.
The elements in a column on the periodic table form a group (or family) because they have similar physical and chemical properties.

The alien periodic table is a hypothetical concept based on the idea that elements could exist in unknown parts of the universe with different properties from those we know on Earth. It is not complete because our understanding of the universe is limited, and we have not discovered all possible elements or their properties.
Because the elements progress in a periodic function.
in 1869 periodic trends in the properties of the then-known elements
Because the properties of the elements change in a periodic fashion. In the early versions, when fewer elements were known, the chemically similar elements were thought to occur every eight positions.
because of the elements
Because they are elements.
Because they are natural elements of earth.
