Use the information for the isotopes of X to calculate the average atomic mass of X, and identify the element. It can be divided into smaller particles that all have the same properties. It consists of subatomic particles, each having its own properties. It does not have all the properties of a larger amount of carbon. It is the same as an isotope and an ion of carbon.

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)
