Why are metals malleable?

• They are shiny

• The electrons are held tightly within the lattice structure making it strong

• The electrons are delocalized and able to move between the atoms

• The electrons are shared between two metal ions and this holds the atoms together

Which of the following pairs of elements would NOT react to form an IONIC compound?

• sulfur and phosphorus

• sodium and iodine

• iron and oxygen

• aluminum and bromine

What are valence electrons?

• The total number of electrons in an atom

• The number of electrons in the outermost shell

• The number of electrons in the second shell

• The number of protons in the outermost shell

An ionic bond is

• the forces of attraction between the free-floating valence electrons and the positively charged metal ions.

• The electrostatic force between oppositely charged cations and anions

• an electron in the highest occupied energy level of an atom

• Atoms in most compounds tend to achieve the electron configuration of a noble gas.
