the most polar element is ???

hint - 4.0 is the electronegativity

• hydrogen

• oxygen

• fluorine

least polar element

hint - 2.1

• hydrogen

• fluorine

• oxygen

• phosphorous

• nitrogen

how do you find the polarity of a covalent bond using numerical means ???

• find the difference between the polarity of each molecule used

• find the difference between the electronegativity of the atoms used

• find the sum of the electronegativity of the atoms used

ΔE = E2 - E1 must be between 0.4 - 2.0 to be a ????

• polar covalent bond

• nonpolar covalent bond

• ionic bond

TRUE or FALSE

if the difference in electronegativity is greater than 2, it is a/an __________________

• ionic bond

• iconic bond

• covalent bond

• nonpolar bond

covalent bonds usually follow the ____________

• octet rule

• oui rule

• eighths rule

covalent bonds are always:

(think enemies to lovers, opposites attract)

so they can meet the octet rule

• nonmetal + nonmetal

• nonmetal + metal

• metal + metal

TRUE or FALSE ???

single bonds form when atoms share one pair of electrons (2 electrons)

• TRUE

• FALSE

• TRUE

• FALSE
