Question 3
•The last three electron configurations all have similar valence electrons 3s23p5 4s24p5 5s25p5 because they all have 7 valence electrons and are in the same group/column. They are halogens.

Noble Gas Electron Configuration 10/28/10• The noble gas electron configuration of an
element starts with the noble gas that comes before the element in brackets and then continues from there to the element.
• Ex. For the element Ca, that would be [Ar]4s2
• The valence electrons are the highest level electrons. For example, if the configuration is [Kr]5s24d105p4 , the valence electrons are 5s25p4 .
