The periodic table is organized by this number
What is the atomic number?
This is the three trends we learned about the periodic table
What is electronegativity, ionization energy, and atomic radius?
These are the two types of elements that make up an ionic bond
What is a metal and a nonmetal

What is protons & electrons?
Both of these trends increase up and to the right on the table
What are ionization and electronegativity?
This is what happens to the electrons in an ionic bond
What is they are transferred?
This is what happens to the electrons in a covalent bond
What is they get shared? Sharing is caring, sharing is covalent.
