Answer:
Did the activities help you uderstand. the topic? Why?
The more people (electrons on the most outer layer), the closer they get to the nucleon, thus making the radius smaller. An atom gets larger as the number of electronic shells increase; therefore the radius of atoms increases as you go down a certain group in the periodic table of elements.
It tell the number of electrons
THen they would have a filled outer electron shell....and they would be negative with a -1 charge.....and be more likely to donate that electron to a metal to from a salt.
