|---|---|---|---|---|---|
| what is covalent bonding? | it is the sharing of electrons between two different nuclei to form a molecule ( between two nonmetals
🗑
|
||||
| what is a bonding electron? | pairs of valence electrons that are shared between atoms
🗑
|
||||
| what is a lone pair aka non bonding electron? | they are pairs of valence electron on an atom that are invoved in electron sharing
🗑
|
||||
| what is a single covalent bond? | a bond in which two atoms share 1 pair of electrons
🗑
|
||||
| what is a double covalent bond? | a bond in which 2 atoms share 2 pairs of electrons
🗑
|
||||
| what is triple covalent bond? | a bond in which 2 atoms share 3 pairs of electrons
🗑
|
||||
| what is electronegativity? | it is the measure of an atoms attraction for electrons that it shares with another atom in a chemical bond
🗑
|
||||
| How can one tell if an atom has a high or a low electronegativity by looking at the periodic table? | As one goes up and to the right of the periodic table the electronegativity increases
🗑
|
||||
| what else can electronegativity determine? | it can determine the degree of sharing between bonded atoms
🗑
|
||||
| what is bond polarity? | the measure of the degree in equality in sharing of electrons between two atoms in a chemical bond
🗑
|
||||
| what is a nonpolar molecul? | the symmetrical distribution of electron charge
🗑
|
||||
| what is the polar molecule? | a molecule in which there is an unsymmetrical distribution of electron charge.
🗑
|
||||
| how can atomic size be determine by looking at the periodic table? | it increases as one goes down and to the left of the periodic table.
🗑
|
||||
| what is repulsion? | describes the distance between bonding and nonbonding pairs of electrons
🗑
|
||||
| what is molecular geometry? | 3 dimensional arrangement of atoms within a molecule
🗑
|
||||
| what is vsepr? | it is the set procedure for predicting a 3 dimensional geometry of a molecule.
🗑
|
||||
| what is the angle of a tetrahedral? | 109.5
🗑
|
||||
| what is the angle of a linear? | 180
🗑
|
||||
| what is the angle of trigonal? | 120
🗑
