Hey girl, you look like a nonmetal. Waddup, I'm sodium, a metal. I got one valence electron to share with you.
Hi, sodium! I'm flourine, and yes I am a nonmetal, and wow, to make a stable bond I need just one more valence electron!
Well, I'm a soft metal, and I have a low melting point. You?
Well, sodium, tell me about yourself!
Wow! How 'bout we get out of here, Fluorine?
I like an element with sass...
Well, not to brag, but I'm the most reactive and electronegative of all the elements. I also react violently with water.
Is this the one?
HOLY MENDELEEV! What's happening?
I THINK WE'RE BONDING!
And they lived out the rest of their happy days together as sodium fluoride. They corroded aluminum together, they treated infections together, they did everything.
