Question

pure gold is called 24 - karat gold. typically, jewelry is not made of 24 - karat gold because it is so soft that it is easily damaged. instead, gold is usually mixed with other metals to make more durable jewelry. for example, 18 - karat gold is 75% gold and 25% other metals. complete the explanation below. gold is held together by ▼ bonds. in this type of solid, the atoms are ▼, making gold a malleable and soft material. show periodic table

Explanation:

Gold is a metal, and metals are held together by metallic bonds. In metallic solids, the atoms are arranged in a lattice with delocalized electrons, and the layers of atoms can slide past each other (they are mobile or can slide), which gives metals properties like malleability (can be hammered into shapes) and softness in the case of pure gold. So the first blank should be "metallic" and the second blank should be something like "able to slide past each other" (or "mobile", "arranged in layers that can slide", etc.).

Answer:

First blank: metallic; Second blank: able to slide past each other (or similar description about atomic mobility in metallic solids)
