Answer

Metals typically exhibit high melting and boiling points, which are indicative of strong metallic bonds. Element 1 has a melting point of 1538°C and a boiling point of 2862°C, suggesting it can withstand high temperatures before changing state. Additionally, it is a conductor of electricity, which is a key characteristic of metals, as they contain free-moving electrons that facilitate electrical conduction. In contrast, Elements 2 and 3 exhibit low melting and boiling points, along with being non-conductors, which is characteristic of non-metals.
