Boiling point decrease at high altitude.
Electrovalent compounds have high melting and boiling points because they have strong electrostatic forces of attraction between the positively charged metal ions and negatively charged non-metal ions. These forces require a significant amount of energy to overcome, resulting in high melting and boiling points for these compounds.
The structure of a compound will dictate what intermolecular forces hold the molecules together. The stronger these forces, the higher will be the boiling point.

Metallically bonded compounds have high melting and boiling points due to the strength of their bonds. Metallic bonds are very strong and therefore take a lot of energy to break, which could be heat. This is why lots of heat energy is needed to break down each individual metallic bond
Melting and boiling points are different for each compound or element.
Elements have fixed melting and boiling points, while compounds have varying melting and boiling points depending on their composition. Mixtures do not have fixed melting and boiling points, as they are composed of multiple substances which each have their own individual melting and boiling points.
No, the trends for melting points and boiling points in nonmetals are generally different from those in metals. Nonmetals typically have lower melting and boiling points compared to metals, which tend to have high melting and boiling points due to strong metallic bonds. In nonmetals, the melting and boiling points can vary significantly based on molecular structure and intermolecular forces, with noble gases having very low points and some covalent network solids like diamond having high points. Therefore, while both groups exhibit trends, the underlying reasons and values differ significantly.
Ionic compounds are composed of positively and negatively charged ions arranged in a regular, repeating three-dimensional pattern within the crystal lattice. The ions are held together by strong electrostatic forces of attraction known as ionic bonds. Ionic compounds tend to have high melting and boiling points due to the strong interaction between the ions in the crystal lattice.
Which metal needs to be specified. Look in a Chemistry book or reference book. All metals have their own melting and boiling points - that's one of the ways we identify which metal the item is made of.
Ionic compounds are basically the combination of a metal and a non-metal. However, its high melting points and boiling points are part of the physical properties of ionic compounds, and high heat is usually required to break the bonds of ionic compounds. The ions which are held together by strong electrostatic force of attraction may results in high melting point and boiling point.
