Necesito que me ayuden con esta pregunta lo antes posible plz¡¡¡¡¡¡ -la capacidad máxima de cada electrónica es igual a
2n2, donde n es el número de la capa. Usando esta
fórmula se puede determinar que la primera capa no
puede contener mas de 2 e-, indique cuál sería la
capacidad máxima de la segunda y tercera capa.

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)
