Ionic Bonding Lesson

Element X is in Group 2 and element Y is in Group 17. What happens when a compound is formed between these two atoms?

• X loses electrons to Y to form an ionic bond

• X loses electrons to Y to form a covalent bond

• X gains electrons from Y to form an ionic bond

• X gains electrons from Y to form a covalent bond.

Which substance has a chemical formula with the same ratio of metal ions to nonmetal ions as in potassium sulfide? (hint: first determine the chemical formula for potassium sulfide... then determine the ratio of metals to nonmetals. Finally, consider your answer choices. Take your time!)

• sodium oxide

• sodium chloride

• magnesium oxide

• magnesium chloride

Answer explanation

Notice... what group is potassium? What about sulfur? Compare the groups to the groups of the elements in the correct answer choice (sodium oxide)

Which substance has a chemical formula with the same ratio of metal ions to nonmetal ions as in magnesium oxide? (hint: first determine the chemical formula for magnesium oxide... then determine the ratio of metals to nonmetals. Finally, consider your answer choices. Take your time!)

• sodium sulfide

• sodium fluoride

• barium sulfide

• magnesium fluoride

Answer explanation

Notice... what group is magnesium? What about oxygen? Compare the groups to the groups of the elements in the correct answer choice (barium sulfide)

What type of bonding occurs when electrons are transferred from one atom to another?

• Covalent Bonding

• Ionic Bonding

• Metallic Bonding

• Hydrogen Bonding

What is the main difference between ionic and covalent bonding?

• Ionic bonding involves the sharing of electrons, while covalent bonding involves the transfer of electrons.

• Ionic bonding involves the transfer of electrons, while covalent bonding involves the sharing of electrons.

• Both ionic and covalent bonding involve the sharing of electrons.

• Both ionic and covalent bonding involve the transfer of electrons.

Which of the following is a property of ionic compounds?

• Low melting point

• High melting point

• Poor electrical conductivity when dissolved in water

• Soft and flexible

Ionic bonds typically form between

• A metal and a nonmetal

• Two nonmetals

• Two metals

• A metalloid and a metal

An ionic bond forms when

• valence electrons are shared back and forth (move between) two atoms.

• a sea of mobile electrons surround the cations and they then become negativly charged

• valence electrons are transferred from one atom to another, forming charged ions that are then pulled together by attraction between opposite charges

• none of the above
