The period to which the element belongs

On the right side of the periodic table
==Yes== Hydrogen, a gas, is found on the left side of the periodic table. And it depends on which periodic table you look at. The standard 18 column ones have hydrogen on the left, but, a geologists' periodic table may have more (sorry, I'm not a geologist, I just know there is such a thing). But I think you mean the everyday periodic table... So yes, hydrogen.
On left side and center of 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)"
the nonmetallic elaments are on the right side of the periodic table
the vertical columns in a periodic table are called groups.
On the left side of the periodic table.
