Where are the nonmetals located on the periodic table of elements?

Nonmetals are found on the right hand side of the periodic table beside noble gases.If you're looking at the periodic table of elements, imagine that there are steps with Boron (B) being on the highest step. Then on the next step below that is Silicon (Si) and so on until Astatine (At). Everything to the right of those steps are non-metals. Everything to the left are metals.


What happens to the atomic number as you go from left to right across the periodic table and why does this happen?

Periods on the periodic table refer to the rows of elements. As the elements progress to the right, the atomic numbers increase, usually in steps of 1.


Where are nonmetals located in the periodic table?

they are located in the right corner of the Periodic Table i think


What does the stair- step line on the periodic table tell you?

The stair step that is seen in the group 3-7 of the representative element ( the right most side of the Periodic Table) divides the table of elements into two..The right side of the stairs are the non metals (eg is the C, S, Cl etc..) They possess the characteristic of non metals ( poor conductor of heat and electricity etc...)The left side are the metals ( well known of it are Gold, Silver, Platinum)They are malleable, have high melting point, good conductors of heat and electricity etc...)And those around the stair steps are the metalloids (eg. Boron, Silicon, Germanium, Arsenic, Antimony, Tellurium, and Polonium)have a half characteristic of metals and non metals..>>>They are semi conductor of heat and electricity and reacts as metal or non metal depending on the element you bond in them..


How does the atomic number change as you move left or right of the periodic table?

left to right - increases (by 1s)right to left - decreases (by 1s)top to bottom - increases (big steps)bottom to top - decreases (big steps)
