why metallic solids are soft to hard
Lanthanides exist as solids at room temperature and pressure. They have metallic properties and are typically soft, malleable, and ductile.
In metallic solids, the attractive forces that stabilize the structure primarily come from metallic bonds, which are formed by the sharing of electrons among the metal atoms. These bonds are strong and are responsible for the high melting points and conductivity typically associated with metals. Additionally, metallic solids may also experience some degree of Van der Waals forces between atoms.
Metallic solids do not exhibit brittle behavior because their atoms are arranged in a way that allows for the movement of electrons, providing them with ductility and malleability.
Metallic bonds are typically considered to be relatively soft compared to other types of bonds like ionic bonds or covalent bonds. This is because the sea of delocalized electrons in metallic bonds allows for the atoms to move past each other more easily, giving metals their characteristic malleability and ductility.
No, gold and platinum are not ionic solids. They are metallic elements that form metallic bonds with delocalized electrons. Ionic solids are formed by the electrostatic attraction between positively and negatively charged ions.
Metallic solids are composed of individual atoms.

The mineral that is soft and metallic is talc. Talc is known for its greasy feel and can be easily scratched with a fingernail, making it one of the softer minerals on the Mohs scale.
All Metals except Hg (Mercury) are solids at room temperature.
Solids can be categorized into crystalline and amorphous solids based on their internal structure. Crystalline solids have an ordered and repeating structure, while amorphous solids lack a repeating pattern. Solids can also be classified based on their electrical conductivity as conductors, semiconductors, or insulators.
