4. elements in groups 1,2 and 13-18 in the modern periodic table
6. an ion that has a positive charge
9. elements in groups 3-12 in periodic table that are divided into transitional metals and inner transition metals
11. the energy to remove an electron from a gaseous atom and increases moving left to right and decreases moving down a group

1. refers to the recurring trends that are seen in the element properties
2. a model that uses electron-dot structures to show how electrons are arranged in molecules paired in dots
3. it indicates the relative ability of an element's atom to attract electrons in a chemical bond
5. inner electrons shielding outer electrons from the nucleus
7. the electrons in an atom's outermost orbitals that determines the chemical properties of an element
8. an ion that has a negative charge
10. an atom that has a positive or negative charge
