What is double displacement?
100
It says that atoms are more stable when their valence shell is full (or empty)
What is the octet rule?
100
It's the type of bond in which electrons are shared.
What is a covalent bond?
100
It's the measure of the amount of space an object occupies, measured in liters in the SI system.
What is volume?
200
One mole of this element has a mass of 24.305 grams.
What is magnesium?
