How is e related to a period of elements?
e generally increases from right to left.
e generally decreases from right to left.
oe is constant within any given period.

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)

Idon’t know how to solve this question

This is a characteristic of the elements in the periodic table that shows a pattern. it may increase or decrease across or down the table.
