Metal atoms tend to give away valence electrons when they bond with nonmetal atoms. What type of bond will form between the metal and nonmetal atoms and why does this bond form?

A
A covalent bond will form because electrons are shared.
B
An ionic bond will form because electrons are shared.
C
An ionic bond will form because electrons are transferred.
D
A covalent bond will form because electrons are transferred.

Lead is malleable, so it can be pounded into flat sheets without breaking. How does the bonding within lead help to explain this property?

A
Covalent bonds involve valence electrons that are removed from one atom and given to another, so the pounding helps the electrons move.
B
Metallic bonds involve valence electrons that are removed from one atom and given to another, so the pounding helps the electrons move.
C
Covalent bonds involve valence electrons that are shared between two metal atoms, so the bonds are strong enough to resist the pounding.
D
Metallic bonds involve many valence electrons shared by many atoms, so the bonds can move around as the metal is pounded.

Fluorine cap f and bromine Br are in the same group on the periodic table. How do atoms of these elements compare when they form bonds?

A
Both a fluorine atom and a bromine atom lose one electron, and both atoms become stable.
B
A fluorine atom becomes stable by gaining one electron, but a bromine atom cannot become stable by gaining only one electron.
C
A fluorine atom becomes stable by losing one electron, but a bromine atom cannot become stable by losing only one electron.
D
Both a fluorine atom and a bromine atom gain one electron, and both atoms become stable.
