Ionic Bonding

Which of the following is NOT a step in forming an ionic bond?

• One atom shares its electrons with another one.
• Opposite charged ions form due to e- transfer
• One atom gives electrons to another one
• Opposite charged ions attract

Why do ionic bonds form?

• So the number of protons equals the number of electrons.
• To stabilize the atom with a full outer shell.
• So an atom can become unstable.
• So atoms will stick together to form molecules.

What is the charge on a noble gas & why?

• 0; they don't exchange electrons
• +1; they give away an electron
• -1; they gain an electron
• 1; they form only single bonds

 Which of the following is the correct formula for these two ions:
Al⁺³ +  S^-2

• AlS₃
• Al₂S₃
• Al₃S₂
• Al₃S

What type of elements will form an ionic bond?

• Metals + Metals
• Nonmetals + Nonmetals
• Metals + Nonmetals
• None of the above

Which of the following describes the strength of an ionic bond?

• Middle - Each atom shares an octet
• Middle - One atom gains an octet & the other loses.
• Weakest - it only forms because of another bond forming
• Strongest - each atom receives a "permanent" octet.

To form a charge of +2 an atom must _ electrons.  To form -3 it must _ electrons.

• Gain 2; Lose 3
• Gain 3; Lose 2
• Lose 2; Gain 3
• Lose 3; Gain 2
