(2Q) Chemical Bonding and The Shapes of Molecules

Question 1

This type of interaction is observed between atoms with large differences in their tendencies to lose or gain electrons and is achieved via electron transfer

Answer 1

Ionic Bond

Question 2

Once the electrons of an ionic bond have been transferred to the non-metal, both the metal and the nonmetal become ___.

Answer 2

ions

Question 3

In ionic bond: Metal is ____ charged and Non-Metal is _____ charged.

Answer 3

positively, negatively

Question 4

tend to have higher melting and boiling points.

Answer 4

Ionic

Question 5

They are hard and brittle and conduct electricity when dissolved in water.

Answer 5

Ionic

Question 6

are formed when atoms reach stability by sharing electrons (rather than fully gaining or losing them)

Answer 6

Covalent

Question 7

The more electrons that are shared between two atoms, the _____ and _____ their bond will be.

Answer 7

shorter and stronger

Question 8

are brittle solid, have relatively low melting and boiling points, and are poor conductor of heat and electricity

Answer 8

Covalent

Question 9

high vapor pressure, which makes them volatile and good as fuels.

Answer 9

Covalent

Question 10

Lewis structure created by

Answer 10

Gilbert Lewis

Question 11

Most metals have how many valence electrons? This can be easily removed because of their relatively low ionization energy

Answer 11

1-3

Question 12

Nonmetals, having high electron affinity, can

Answer 12

gain valence electrons to fill their s and p orbitals and form an octet

Question 13

is the difference between the valence electrons in an isolated atom and the number of electrons assigned to that atom in a Lewis structure

Answer 13

Formal charge

Question 14

It is imperative to remember that atoms are more stable when they
have

Answer 14

Lesser charge

Question 15

Negative formal charges should be assigned to more

Answer 15

electronegative atoms

Question 16

the angles and distances between each atom, bonding pair, and lone pair of electrons are determined by the

Answer 16

attractive and repulsive forces governing all matter.

Question 17

the size and shape of a molecule of a substance, together with the strength and polarity of its bonds, affect the

Answer 17

physical and chemical properties of molecules

Question 18

The approach in predicting molecular geometry

Answer 18

Valence Shell Electron Pair Repulsion Theory (VSEPR).

Question 19

VSEPR Theory is anchored from the assumption
that all electron pairs in the valence shell
around a central atom _________

Answer 19

repel one another

Question 20

In VSEPR Theory, electron pairs stay far apart from each other to?

Answer 20

minimize repulsions

Question 21

is determined by the number of bond pairs and lone pairs around the central atom.

Answer 21

Molecular Shape

Question 22

In VSEPR Theory, you should treat multiple bonds as?
