Exploring Ionic Bonding with Sodium Chloride

What is the main goal of an atom in terms of its valence shell?

• To have an equal number of protons and electrons

• To have more protons than electrons

• To have a full valence shell

• To have more electrons than protons

How many protons and electrons does a neutral sodium atom have?

• 11 protons and 11 electrons

• 10 protons and 11 electrons

• 12 protons and 11 electrons

• 11 protons and 10 electrons

What is the atomic number of chlorine?

• 18

• 10

• 17

• 11

Why is sodium considered 'unhappy' in its neutral state?

• It has more protons than electrons

• It has a full valence shell

• It has only one electron in its valence shell

• It has too many electrons

What happens to sodium's valence shell when it gives an electron to chlorine?

• It disappears and a new full valence shell is formed

• It remains the same

• It gains more electrons

• It becomes negatively charged

What charge does chlorine acquire after gaining an electron from sodium?

• Positive charge

• No charge

• Negative charge

• Neutral charge

What is the resulting charge on sodium after it loses an electron?

• No charge

• Positive charge

• Negative charge

• Neutral charge

What is the term used to describe an atom with a charge?

• Compound

• Molecule

• Ion

• Isotope

Why do sodium and chlorine atoms stick together after forming ions?

• Because they have opposite charges

• Because they have the same charge

• Because they have the same number of protons

• Because they share electrons

What is the final product formed when sodium and chlorine ions attract each other?

• Sodium chlorate

• Sodium metal

• Chlorine gas

• Sodium chloride
