Explicação
## Step 1<br />The problem is asking us to identify the category to which copper belongs. The options provided are Noble Gases, Alkali Metal, Halogen, and Transition Metal.<br /><br />## Step 2<br />Copper is a chemical element with the symbol Cu and atomic number 29. It is a transition metal, which is a group of elements in the periodic table that have similar properties.<br /><br />## Step 3<br />Noble gases are a group of chemical elements with similar properties; they are all odorless, colorless, monatomic gases with very low chemical reactivity. Alkali metals are a group of chemical elements in the periodic table with similar properties; they are all shiny, soft, highly reactive metals at standard temperature and pressure and readily lose their outermost electron to form cations. Halogens are a group of chemical elements that are found in Group 17 of the periodic table. They are known for their reactivity and ability to form salts when combined with metals.<br /><br />## Step 4<br />Copper, however, is a transition metal. Transition metals are elements that are found in Groups 3-12 of the periodic table. They are characterized by their ability to form stable, colored compounds and their high melting and boiling points.
