Answer:
1.) Elements in higher periods have larger atomic radii and their electrons are located in higher energy levels.
2.) The period number is greater than the energy level where valence electrons are located.
3.) Atoms with 5 or more electrons will gain or lose valence electrons to have a total of eight valence electrons.
4.) The number of valence electrons in an atom or ion can be represented by a(n) Lewis Symbol.
5.) Generally, elements in the same period that have a smaller atomic radius will have higher ionization energies than elements with larger atomic radii.
6.) Generally, when comparing representative elements in the same period, elements with more valence electrons with have an ionization energy that is greater than elements with fewer valence electrons.
7.) Elements with the most metallic character are more likely to gain electrons than elements with the least metallic character.
