The halogens can be found in column 17 of the Periodic Table. They are called Group VII because they all have 7 electrons in their outer orbitals.
The lighter ones (Fluorine & Chlorine) are gases at room temperature. Bromine is a liquid, while Iodine & Astatine are solids. All tend to rapidly react by gaining an electron (they are good oxidizers).
The noble gases can be found in column 18 of the Periodic Table. They are called Group VIII because they all have 8 electrons in their outer orbitals.
Having full outer orbitals, the noble gases usually do not react with other elements. This is why they are sometimes called the Inert Gases. Several compounds of Xenon and Fluorine and Oxygen have been make and studies, however.

Nonmetals are brittle if they are solids. They are colorful. Many are gases, one liquid. They do not conduct electricity or heat.
Noble gases are inert, they do not react. Halogens are very reactive. They are gases, a liquid and solids, The gases are colorful, green, yellow, and purple for iodine gas when it sublomes.

Halogens form salts and Noble gases are inert.
