In terms of electrons, what happens when sodium oxide is formed?

When metals react with non-metals, electrons are transferred from the metal atoms to the non-metal atoms, forming ions. ... Consider reactions between metals and non-metals, for example, Sodium + chlorine = sodium chloride. Magnesium + oxygen = magnesium oxide.

I hope this answers your question
 

So what you would do is go through and add 3 teaspoons(tsp) 6 times because of the 6 tablespoons(tbsp). which will give you an answer of 18. another way is to multiply 3x6=18.
