Question

the word \atom\ comes from a greek word for \indivisible.\ in what way are atoms indivisible?
they cannot be separated once theyve bonded with other atoms.
they cannot be broken apart without losing their chemical properties.
they cannot form bonds with other atoms.
they cannot gain or lose electrons.

Explanation:

• Analyze Option 1: Atoms in a bond can be separated (e.g., in chemical reactions), so this is incorrect.
• Analyze Option 2: An atom is the smallest unit of an element that retains its chemical properties. If broken into subatomic particles (protons, neutrons, electrons), it loses its chemical identity (properties of the element), so this matches the "indivisible" concept in terms of chemical properties.
• Analyze Option 3: Atoms do form bonds (ionic, covalent, etc.) with other atoms, so this is wrong.
• Analyze Option 4: Atoms can gain/lose electrons (forming ions), so this is incorrect.

Answer:

B. They cannot be broken apart without losing their chemical properties.
