Why must a Roman numeral be used in the name of ionic compounds containing transition metals (as well as tin and lead)?
A.Transition metals are multivalent meaning their ions can have multiple charges.
B.The Roman numeral indicates how many atoms of the transition metals are bonded in the compound.
C.Because transition metals are in the d-block of the periodic table.
D.Roman numerals are cool!

What is the formula for the following compound: aluminum phosphide?
Which of the following statements is true?
A.ionic bonds form between two nonmetal atoms because one atom loses electrons and the other gains electrons to form ions with opposite charges.
B.ionic bonds form between two nonmetal atoms because the two atoms share valence electrons
C.ionic bonds form between a metal and a nonmetal atom because the metal will lose electrons and the nonmetal will gain electrons to form ions with opposite charge.
D.Ionic bonds form between two metal atoms because each atom will lose electrons causing the ions to attract each other to regain electrons.

What is the trend for ionic radius down a group as the atomic number increases?
A.the ionic radius increases because the electrons are on higher energy levels going down a group
B.the ionic radius increases because the number of protons increases which makes the atom larger
C.the ionic radius decreases because the increasing number of protons pulls the electrons in more tightly
D.the ionic radius decreases because there are fewer valence electrons in atoms going down a group
