Consider the two electron arrangements for neutral atoms A and B. What is the atomic number of A?
A - 1s2, 2s2, 2p6, 3s1
B - 1s2, 2s2, 2p6, 5s1

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.

Its a hope this
