A) The squares represent noble gases.
B) Color coding indicates the state of matter at room temperature.
C) The squares represent metals.
D) The color indicates the atomic number.

Answer 1

The color coding of the squares in the periodic table represents the state of matter at room temperature.

Step-by-step explanation:

The color coding of the squares in the periodic table represents the state of matter at room temperature. It does not indicate noble gases, metals, or the atomic number. The background color of the squares denotes whether an element is a metal, metalloid, or nonmetal, while the color of the element symbol represents whether it is a solid, liquid, or gas.
