In a metallic bond, electrons
1) are shared
2) are completely transferred between bonded atoms
3) move freely between the clouds of several atoms
4) move from a high energy level to a low energy level within one atom

Asample of silver (with work function ? = 4.52 ev) is exposed to an ultraviolet light source (? = 200 nm), which results in the ejection of photoelectrons. what changes will be observed if: silver is replaced with copper (? = 5.10 ev) more photoelectrons ejected no photoelectrons are emitted fewer photoelectrons ejected more energetic photoelectrons (on average) less energetic photoelectrons (on average)
