Periodic Table of Elements
The periodic table is a tabular arrangement of the chemical elements , organized on the basis of their atomic number (number of protons in the nucleus), electron configurations , and recurring chemical properties . Elements are presented in order of increasing atomic number, which is typically listed with the chemical symbol in each box. The standard form of the table consists of a grid of elements laid out in 18 columns and 7 rows, with a double row of elements below that. The table can also be deconstructed into four rectangular blocks : the s-block to the left, the p-block to the right, the d-block in the middle, and the f-block below that.

Metals |
A solid substance that is a good conductor of heat and electricity. Can be formed into many shapes. |
Metalloid |
"Middle elements" - conduct heat and electricity better than nonmetals, but not as well as metals. Easier to shape than nonmetals, but not as easy as metals. Solid at room temperature. |
Nonmetals |
A poor conductor of heat and electricity. Not easily formed into shapes. |
