One little atom
Sitting all alone
Has eight negative electrons
Which is all he owns
Feeling rather empty
The atom looked with thrill
For a couple more electrons
So his valence he could fill
Along float another pair
Stopping by to say
“Do you need a hand with those?
Or around us should these stay?”
The first atom replied,
Feeling rather large
“Of course my friends—
You’re welcome to this charge!”
So into his orbit
The other two did throw
Their single small electron
So that his orbital may grow
But when they did this
They had a turn of luck
For to the first atom
The other two were stuck!
Although this may seem funny
Try not to ridicule
For when atoms share with others
They form a molecule!
