In a metallic lattice the attractive forces/bonds between metal ions and the surrounding mobile sea of electrons are strong. Strong attractive forces/bonds require a high temperature to be overcome/broken. E.g. The MP for chromium is 1900oC, and for iridium, 2450oC.
(* Some metals have low melting points such as Mercury, -39oC, and the Group 1 metals: Li = 180oC, Na = 98oC, rubidium = 39oC, caesium = 29oC.)
The attractions, between the polar solvent molecules and the metallic lattice cations/electrons, are not strong enough to pull them from the lattice. (Also: electrons are too tiny to be successfully surrounded by solvent molecules.)
Non-polar molecules have no permanently charged parts that can be attracted to the charged cations/electrons.
The mobile sea of electrons can move within the metallic lattice to be an electric current.
Even when the metallic lattice has been broken by high temperatures, so that the metal is in the liquid state, there is still a mobile sea of electrons which can move to be an electric current. (E.g. Liquid mercury conducts.)
The mobile sea of electrons can move around metal cations in the lattice as the cations are moved. This allows the metal to change shape without breaking.

What are 3 chemical properties for germanium?
Germanium is a semiconductor that has an atomic number of 32. It forms covalent compounds with elements like oxygen, chlorine, and hydrogen. Germanium exhibits both metallic and non-metallic properties.
What are the properties in the boron family?
The boron family, also known as Group 13, includes boron, aluminum, gallium, indium, and thallium. These elements share the common property of having three electrons in their outermost shell, which allows them to form +3 oxidation states in compounds. They exhibit both metallic and non-metallic properties, with decreasing metallic character going down the group.
What type of compound contains metallic bonds?
Metallic compounds contain metallic bonds, where electrons are delocalized and free to move throughout the material, leading to properties such as high electrical conductivity, malleability, and ductility. Examples include metals like copper, iron, and aluminum.
Is mg covalent ionic or metallic?
Mg is a metallic element, meaning it has properties characteristic of metals such as high electrical conductivity and luster. It forms ionic compounds when it reacts with non-metals, such as in MgCl2 (magnesium chloride).
What is the period 5 boron family?
The boron family in period 5 of the periodic table includes the element boron (B) and its compounds. Boron is a metalloid element and forms compounds like borates. It also includes elements like aluminum (Al) and gallium (Ga), which exhibit both metallic and non-metallic properties.
What is a malleable metal?
Malleability is one of several general physical properties of metals and metallic compounds.
Do metallic compounds have the same properties as the original metals or new proerties?
Chemical compounds have very different properties compared to metals.Metallic compounds have more similar qualities to original metals. All of these metals are good conductors of heat. All of them have a luster.
Do metallic compounds have molecules?
Metallic compounds typically do not have distinct molecules like covalent compounds do. Instead, they consist of metal atoms arranged in a lattice structure, where electrons are delocalized and shared among many atoms, forming a "sea of electrons." This structure provides metallic properties such as conductivity and malleability. Therefore, while metallic compounds are composed of atoms, they do not form individual molecules.

Metallic submetallic and nonmotallic are properties of?
Metallic, sub metallic, and nonmetallic are properties of the mineral luster.
Why is metallic nature is not considered an innate property of metals?
Metallic nature is not considered an innate property of metals because some metals can lose their metallic properties under certain conditions, such as forming compounds with nonmetals or being subjected to extreme temperatures. Additionally, some nonmetals can exhibit metallic properties under specific conditions, blurring the distinction between metals and nonmetals based on metallic behavior.
