Covalent, Ionic, and Metallic Bonds Flashcards
Ionic Bonds (key word)
TRANSFERRED
electrons are transferred from one atom to another
(Large difference in electronegativity)
Covalent bonds (key word)
SHARED
electrons are shared between two atoms
Type of ionic bond?
Metal & nonmetal
Types of Covalent bond?
Nonmetal & nonmetal
Polar covalent?
Unequal sharing of electrons
Non polar covalent?
Equal sharing of electrons
Metallic bond?
Metal & metal
What is a metallic bond often called?
Electron sea
Mobile electrons shared by all atoms
What elements satisfy the octet rule without forming compounds?
Noble gases
As atoms bond what happens to potential energy?
It’s decreases and atoms form more arrangements
Ionic bonds are high in what?
Almost everything
Covalent bonds are low in what?
Almost everything (compared to ionic bonds)
0-0.3 is what type of bond?
Non polar covalent bond
Equal share
0.3-1.7 is what type of bond?
Polar covalent bond
Un equal share of electrons
1.7-3.3 is what type of bond?
Ionic bond
Electron transfer
