An electron is on a -2.5 eV energy level. The electron is struck by a 2.5 eV photon. What will most likely happen?

explanation:

venn diagram is pictorial representation with of circles showing the relation between two finite sets or things. the intersection part of two circles conveys the relation present in between those sets or things.

here in the venn diagram of sand and salt two circles represent sand and salt. but the area falling under the intersection of these circle represents the mixture of sand and salt.

so, in a venn diagram the mixture will be placed in a middle that is in between the intersection of two circles.

i believe that it is a exoplanet

the electron configuration that you gave me has 16 electrons ergo it has 16 protons ergo it is the element sulfur.

i think its 100.

hope this !
