As we move across a period from left to right, nonmetallic character _____.
Step-1:
The elements in periodic table are placed in periods and groups. Periods are horizontal rows that has increasing atomic numbers. Groups are vertical columns. The groups have similar chemical properties. There are 7 periods and 18 groups in periodic table.
Step-2:
In periodic table, group 1, 2 are metals, group 17, 18 are non-metals, middle groups are transition metals and zig-zag line along the group 13 to 16 are metalloids.
So, the metallic character is higher on extreme right while the non-metallic character is higher towards the right of the periodic table.
Final answer:
As we move across a period from left to right, nonmetallic character increases.
