3. A. The chemical bonding that result from the attraction between metals atoms and the surrounding _________________ is called __________________. sea of electrons Cometogether… metallic bonding

5. 1. Most metals have very few __________ in their outermost energy shells, and some have vacant outer electron orbitals. That means its valence electrons are _______________ and free to move around. electrons Cometogether… decentralized

7. 2. When metals are next to each other, the valence electrons don’t just stay on their own atom; they roam around the ________ ________________. whole Cometogether… metal complex

9. 3. Each metal atom allows its electrons to _____________, so these atoms become positively charged cation. roam freely Cometogether…

11. a. These cations are kind of like a positively charged island and are surrounded by a sea of negatively charged electrons. The attraction between the _______ electrons and the _________center is a metal bond. mobile Cometogether… positive

13. A. In metal bonds, the electrons _____________ around in an electron sea, and this leads to metals’ unique properties. move freely Cometogether…

15. 1. Metal _____________________ well because all of the mobile electrons are free to move towards any attraction. conducts electricity Cometogether…

16. 2. Metals have _______ (shiny) because it reflects incoming light photons (because of the free electrons.) luster Cometogether…

18. 3. It is ___________ because the structure and uniform bonding in all directions of the metal llows the atoms to ______ past each other without breaking. malleable Cometogether… slide

20. a. _____________ is the ability of a substance to be hammered or beaten into thin sheets. Malleability Cometogether…

21. b. __________ is the ability of a substance to be drawn or pulled through a small opening to produce a wire. Ductility Cometogether…
