To determine which statement is false, let's analyze each one based on the details provided:

  1. The atom has an overall charge of 0.

    • This statement suggests that the atom is neutral, which is true for the majority of atoms unless they have gained or lost electrons to become ions.

  2. The atomic number of this atom is 18.

    • The atomic number corresponds to the number of protons in the atom. An atomic number of 18 refers to argon, not chlorine, which has an atomic number of 17.

  3. The mass of the atom is 35 AMU.

    • Chlorine typically has isotopes with atomic masses around 35 (specifically, chlorine-35 has a mass of approximately 35 AMU). This statement could be true, assuming the atom in question is chlorine-35.

  4. This is a chlorine atom.

    • If the previous statements about atomic number, mass, and charge are accurate, this statement could also be true. However, given that the atomic number is incorrect, this could imply the second statement is false.

Based on this analysis, the false statement is:

The atomic number of this atom is 18.
