2.3 Chemical Bonding Flashcards
What happens with electrons during ionic, polar covalent, and nonpolar covalent bonds
They transfer with each other.
What is a nonpolar bond?
Two Nonmetals
No difference in EN
Shares Electrons EQUALLY
What is a polar bond?
Two Nonmetals
Slighter Difference in EN
Shares Electrons UNEQUALLY
What is an ionic bond?
One metal and One Nonmetal
Large difference in EN
Does not share electrons.
What happens to EN as you go across (left to right) the periodic table? Why?
The pull gets stronger.
What happens to EN as you go DOWN the periodic table?
The pull gets weaker.
What do chemical bonds provide?
They provide stability.
What bond would two hydrogen atoms form?
Non-Polar, the EN is equal so the pull is equal between the two.
What bond would two hydrogen and one oxygen form?
Polar, because one has a stronger EN and they are both nonmetals.
What bond would a Potassium and Oxygen form?
Ionic, because on is a metal and the other is nonmetal, the difference in EN is also larger.
