Today, we are learning about Periodic Table Trends!!
This is the distance between the nucleus and the outer electron shell of the atom. When you go across a period, the atomic radius increases. Also the size of the atom will increase as advances down a group.
First, we have the atomic raduis
Which will have a higher atomic radius? Flourine or Chlorine
Chlorine because it is down more in the group.
Correct! God job Joey!
This is the distance between the nucleus and outermost electron shell in an ion. As the ions advance further down in a group, the radius increases too.
Next we have the ionic radius
What are two things that can affect ionic radii?
Effective nucear charge and the sheilding effect.
That's right! Good job, Kirston!
This this the amount of energy it takes to remove a valence electron from an atom to make it into an ion.
