Magnesium is in this group on the periodic table.
What is Alkaline Earth Metals (or Group 2)?
Ionic compounds form when a metal and a non metal do this with their valence electrons.
What is give/take?
When naming molecular compounds, we use this system.
What is the prefix system?
The generic formula AB + C --> CB + A represents this reaction type.

In a Lewis Dot diagram showing the movement of electrons, this shape would be used to satisfy the octet rule for all elements in a Molecular Compound.
What are circles (around the unpaired electrons)?
When energy is inputted to water molecules, they can break down, forming these products.
What are hydrogen gas and oxygen gas?
When you put pH indicator in an unknown substance, it turns yellow/orange. This substance is...
What is acidic?
This is the word used to describe when the same element has different amounts of NEUTRONS.
