Bonding and Polarity

STUDY
PLAY
Polar
When electrons are not shared equally
Non Polar
When atoms of the same element are shared equally
Dipole Moment
Due to the electrons being shared unequally the electrons are on one end of the bond, one area to be more negative than the other. (seperating of charges)
Linear
2 or 3 atoms bonded in a straight line
Bent
2 shared pairs of electrons with 2 unshared pairs
Trigonal Planar
3 Shared pairs of electrons with zero unshared
Trigonal pyramidal
3 shared pairs of electrons with 1 unshared
Tetrehedral
4 Shared pairs of electrons with zero unshared
Covalent Bond
Bond formed when atoms share electrons
Electronegativity
ability of an atom to attract shared electrons (hold together) bonds.
Atoms are more attracted to element with higher electronegavitity
Polar Covalent Bond
Covalent bond in which two atoms have different electronegavitity, causing a seperation of charges
Non Polar Covalent Bond
Non polar bond in which identical or nearly identical electronegativities cause the charges to be distributed evenly.
Usually between two elements of the same
2 metals or 2 metalliods
Covalent bond forms between, because the electrons are held so tightly together that instead of losing or gaining other electrons, they're shared.
2 metalliods or 2 non metals
Non Polar Covalent bonds
Ionic Bond
When atoms transfer or receive electrons from other atoms
Can be positive or negative, depending on the number of electrons
Cohesive Force
Attractive pull
Hydrogen Bond
Loose bonding
Polarity Requirements
geometrical symmetry
dispole movement
symmetry with electronegativity
Double Bond
2 pairs of electrons are shared by a pair of atoms
Triple Bond
3 pairs of electrons shared by a pair of atoms
