Which compound has the least ionic character?

• KBr

• HF

• MgO

• BrCl

The bonds in BaO are best described as

• covalent, because valence electrons are shared

• covalent, because electrons are transferred

• ionic, because valence electrons are shared

• ionic because electrons are transferred

Which property best accounts for the conductivity of metals?

• the relatively high first ionization energy

• the malleability of most metals

• the free electrons in the valence energy levels

• the filled inner electron energy levels

The results of these tests suggest that

• both solids contain only ionic bonds

• both solids contain only covalent bonds

• Solid A contains only covalent bonds and solid B contains only ionic bonds

• Solid A contains only ionic bonds and solid B contains only covalent bonds
