What is the formula for the compound formed by calcium ions and chloride ions? Refer to the periodic table.

• CaCl₃

• CaCl2

Which type of structure do most ionic compounds form?

Which is the correct ion form of barium?

• Ba2–

• Ba2+

• Ba1–

• Ba1+

Which property must be known about

each atom in order to draw an electron-dot

structure?

• bond length

• atomic mass

• ionization energy

• number of valence electrons

Why do metals and nonmetals tend to form

ionic bonds?

• Metals have low electronegativities, so

  they transfer electrons easily to nonmetals,

  forming ionic bonds.

• Nonmetals have lower electronegativities

  than most metals, so they bond tightly

  together, creating ionic bonds.

• Metals and nonmetals have similar

  electronegativities and masses, so they

  share electrons when creating ionic bonds.

• Nonmetals and metals that are bonded have

  atomic masses so different that it causes

  them to form ionic bonds more easily.

Which term describes positive ions?

• cations

• anions

• valanceshells

• VESPER

What is the name of CaCl2

• Calcium chloride

• Calcium chlorine

• Calcide chlorine

• Calcide chloride

What is the formula of potassium sulfide?

• K2S

• KS2

• K3S2

• K2S3
