Lesson 5.2 Flashcards
Define covalent bonding
When 2 non-metals fight over electrons and end up pulled together
Define ionic bonding
Opposite charges with a transfer of electrons between atoms with a large difference in electronegativity
What is electronegativity?
measure of how strongly atoms attract new bonding electrons to themselves
What happens during a polar covalent bond?
Two non-metals with different EN are fighting over electrons and the bonding electrons are shared unequally
What happens during a non-polar covalent bond?
Two non-metals with equal EN are fighting over electrons and the bonding electrons are shared equally
What happens during ionic bonding?
A transfer of electrons occurs between opposite charges atoms with a diff. in EN and one atom gains an electron from the other
When given two atoms, what type of bond will form between them and why?
Depending on the atoms, a covalent bond with form with nonmetals of the same or different EN while ionic bonds will form with the oppositely charges atoms ( metals and nonmetals).
Explain how electronegativity determines what type of bond two atoms will form.
Give an example of two atoms that will form a polar covalent bond and two atoms that will form a non polar covalent bond.
Polar - Hydrogen and Chlorine
Non-polar - Chlorine and Chlorine
Give an example of two atoms that will form an ionic bond.
Sodium and Chlorine
