Chemistry Module 5

which atom in the C-CI bond has a partial negative charge

CI

which of the following is the most electronegative atom (C N O F)

F fluorine is the most electronegative

which of the following is an example of a covalent bond (K-CI AI-CI H-CI AI-AI)

H-CI covalent bonds are typically formed between two nonmetals

identify the correct dipole in the C-Br bond in the Lewis Structure of methyl bromide shown using a vector arrow

I

which of the following is not a covalent bond (N-N Mg-N N-O H-H)

Mg-N typically a nonmetal bonded to a nonmetal is a covalent bond

the molecule HI is

heteronuclear because there are two non identical nuclei in the molecule

the compound NaBr is an

ionic compound

which of the following statements is false

linear molecules cannot have a net dipole moment *linear molecules can easily be given the appropriate arrangement of elements

which atom in the Br-F molecule has a partial negative charge (δ−)

F partial charges are determined by the relative electronegativities of the atoms in a molecule; the more electronegative atom

which of the following is an example of an ionic bond ( K-F C-H Kr-H C-F)

K-F the difference in electronegativity is greater than 1.5 and between a metal and a nonmetal

which of the following is an example of an ionic bond (F-F O-F Na-O Na-Na)

Na-O

the reason an ionic bond forms can best be described as

the energy change for an electron transfer results in a large gain in stability when the ionic bond forms

in a covalent bond

two atoms share valence electrons and those shared electrons form the chemical bond

what happens when an ionic bond forms

two atoms, one atom which is more electronegative than the other, exchange electrons and charges hold the atoms together
