What do you already know about bonding?

Multiple Choice

Why do atoms tend to lose or gain electrons?

• To achieve a full valence shell

• To increase their size

• To become radioactive

• To lose energy

Multiple Choice

• 2

• 6

• 10

Open Ended

Multiple Choice

When sodium loses an electron, what is the resulting charge of the ion?

• +1

• -1

• 0

• +2

Multiple Select

Which of the following statements about cations is/are correct?

• Cations are smaller than their respective atoms

• Cations have decreased electron repulsions

• Cations drop a principal energy level

Multiple Choice

Which of the following statements best describes what happens to metals during bonding?

• Metals gain electrons and become negative ions.

• Metals lose electrons and become positive ions.

• Metals gain protons and become smaller.

• Metals lose neutrons and become larger.

Open Ended

Explain why chlorine needs one more electron to fill its valence shell. What does this mean for its chemical reactivity?

Multiple Choice

After chlorine gains an electron, what is its overall charge and why?

• +1, because it has more protons than electrons.

• 0, because it has equal protons and electrons.

• -1, because it has more electrons than protons.

• +2, because it gains two electrons.

Multiple Choice

Which of the following are true about anions compared to their respective atoms?

• Anions are smaller due to loss of electrons.

• Anions are larger due to additional electron repulsion.

• Anions have fewer protons than atoms.

• Anions are always positively charged.

Open Ended

Describe the process of electron transfer between sodium (Na) and chlorine (Cl) and explain the result of this transfer.

Open Ended

Explain why atoms cannot lose or gain electrons from thin air and must interact with other atoms to transfer electrons.

Multiple Choice

What happens when sodium (Na) gives an electron to chlorine (Cl)?

• Both atoms become neutral

• Na becomes a cation and Cl becomes an anion

• Both atoms become negatively charged

• Na becomes an anion and Cl becomes a cation

Multiple Select
