Electronegativity Periodic Trend - Using the Periodic Table to help determine electronegativity!
Electronegativity is the tendency of an atom to gain an electron. The way I think about it is like tug of war. The stronger an atom can pull in an electron, the higher it’s electronegativity will be. The trend for electronegativity is...

What in the world is IONIZATION ENERGY?!?
Ionization energy is the amount of energy it takes to remove an electron. The stronger the nucleus can hold on to the electron, the more energy that will be needed to remove the electron. The trend for ionization energy is that it...

Periodic Trend - Atomic Size (Radius) Explained!
The periodic trend for atomic size is that the size of the atom gets bigger as you go down the periodic table and from right to left across the periodic table. This trend is sometimes referred to as atomic radius as there is a direct...
