Help! I need a metal that can transfer electrons to me so I can become stable!
... I'm a non-metal, but we can both fill our valence shells (become stable) by sharing electrons in a covalent bond!
H
F
Covalent bond? How does that work?
We just both need to share one of our electrons with each other! Like this:
H
F⁻
Hey! I'm feeling stable now! But why are you so weak?
Yeah... Your electronegativity is higher, so you're pulling the electrons towards you more.
H⁺
F⁻
Electronegativity... what's that?
Electronegativity is an atom's ability to attract electrons... since you have more protons, you have more electronegativity. Since the electrons are unequally shared between us, we are a polar covalent bond
H⁺
F⁻
Let's rearrange and rename ourselves! My group number is lower than yours, so I'll be first, and you'll need a prefix. There's 1 of you, so it would be mono. Also, change the end of your name to ide.
The electrons being closer to you is also why you have a slightly more negative charge and I have a slightly more positive one
H⁺
H⁺
*Note: HF can also be called Hydrogen Fluoride, as Hydrogen can only make one covalent bond, so it's implied that there is only one of the other element.
Perfect! Now together we are Hydrogen Monofluoride! I would need a prefix if there wasn't just one of me, but I come first so I don't have to!
Wooohooo!
