Web19 sep. 2024 · Both the melting and boiling points decrease down the group. When any of the Group 1 metals is melted, the metallic bond is weakened enough for the atoms to move more freely, and is broken completely when the boiling point is reached. The decrease in melting and boiling points reflects the decrease in the strength of each metallic bond. Web21 aug. 2024 · Nonmetal oxides, which form covalent bonds, are simple molecules with low melting and boiling points. Compounds with oxygen in an oxidation state of -1 are referred to as peroxides. Examples of this type of compound include N a 2 O 2 and B a O 2. When oxygen has an oxidation state of -1/2, as in O 2 −, the compound is called a superoxide. denacifikacija definicija https://gitamulia.com
