Question

2 PUNIS

Answer 1

A. Electrons move from the sodium atoms to the oxygen atoms.

Explanation:

When oxygen reacts with sodium, electrons moves from sodium to oxygen atoms. An ionic bond forms between the two ions.

Ionic or electrovalent bonds form between atoms with a large electronegativity difference between them. These are typically metals and non-metals.

• Electrons moves from the metals leaving a net positive charge on it.
• The non-metals gain the electrons making them negatively charged.
• The electrostatic attraction between the two ions results in the formation of ionic bonds.
• In this example, two Na loses one electron each and making its ion resemble Neon atom which is a stable atom.
• Oxygen gains the two electrons and completes its own octet too.
• The two oppositely charged ions attracts and forms a compound.
