Introduction to Ions and Ionic Bonding

The video tutorial explains the concept of neutral and charged atoms, focusing on ions and their charges. It describes ionic bonding as the transfer of electrons between atoms, using sodium and chlorine as examples. The formation of sodium chloride, a common ionic compound, is detailed, highlighting the attraction between oppositely charged ions. The video concludes with a discussion on the crystal lattice structure of ionic compounds, such as salt crystals.

What happens to the charge of an atom when it loses an electron?

• It remains unchanged.

• It becomes positively charged.

• It becomes neutral.

• It becomes negatively charged.

In ionic bonding, what occurs between two atoms?

• They repel each other.

• They share electrons.

• They transfer electrons.

• They merge into one atom.

Which of the following is an example of an ionic bond?

• Nitrogen and hydrogen forming ammonia

• Hydrogen and oxygen forming water

• Carbon and oxygen forming carbon dioxide

• Sodium and chlorine forming table salt

What is the structure called that many ionic compounds form?

• Atomic grid

• Electron cloud

• Crystal lattice

• Molecular lattice

What shape do salt crystals typically form?

• Hexagonal

• Pyramidal

• Cubic

• Spherical
