Electronegativity is...
the strength of an atom to pull electrons from another element
the ability of an atom to lose electrons
the energy required to remove an electron from a specific atom
the strength of an atom to share electrons with another element
Large differences in electronegativity result in __________ bonding between atoms.
Covalent
Mettalic
Ionic
Hydrogen
Hydrogen has an electronegativity of 2.20, fluorine an electronegativity of 3.98. What sort of bond do they form?
0-0.4 = nonpolar; 0.41-1.7 = polar covalent; 1.71+ = ionic
mostly ionic
polar covalent
mostly covalent
nonpolar covalent
Which has the greater Electronegativity:
N or C?
C
N
Which has the greater Electronegativity:
H or F?
H
F
Put these in increasing order of electronegativity:
F, N, B (smallest on left; largest on right)
B < N < F
B < F < N
N < F < B
F < N < B
A bond with a partially negative end and a partially positive end is (as opposed to completely negative and completely positive):
ionic
polar
non-polar
isometric
A diatomic molecule like O2 is always_______ because electrons are shared ________.
pure covalent; equally
polar; equally
nonpolar; unequally
nonpolar; equally
