Metallic Bonding Flashcards
What is metallic bonding?
The electrostatic attraction between a lattice of positive ions and delocalized electrons.
What model is used to describe metallic bonding?
The electron sea model, where electrons move freely among metal ions.
Why do metals conduct electricity?
Due to the presence of free-moving delocalized electrons.
Why are metals malleable?
Because metal ions can slide past each other while maintaining the metallic bond.
What are alloys?
Mixtures of two or more metals or a metal and another element to improve properties.
Why are metals ductile?
The delocalized electrons allow metal atoms to roll over each other without breaking the bond.
Do metals generally have high or low melting and boiling points?
High, due to the strong attraction between ions and electrons.
Why do metals have a shiny appearance?
Free electrons can reflect light, giving metals their characteristic shiny
