🗑
|
||||
| an atom of an element w/the same number of protons but different number of neutrons | Isotope
🗑
|
||||
| occures in metals,many atoms share many electrons, **valence electrons create a sea of electrons that flow through the nucleus | metallic bonding
🗑
|
||||

🗑
|
||||
| conduct electricity,are malleable, ductile, high density due to lattice structure | metals
🗑
