To identify the image as a proper model of a neutral lithium atom, you should look for specific characteristics that are indicative of lithium's atomic structure.
1. **Electron Configuration**: A neutral lithium atom has three electrons. In a model, you would expect to see three negatively charged electrons orbiting the nucleus.
2. **Protons in the Nucleus**: Lithium has an atomic number of 3, meaning it has three protons in its nucleus. The presence of three positively charged protons should be evident in the model.
3. **Neutrons**: The most common isotope of lithium has three neutrons. If the model depicts neutrons alongside protons in the nucleus, that would further confirm it represents lithium.
4. **Overall Charge Balance**: A neutral atom means that the number of protons (positive charges) should be equal to the number of electrons (negative charges). If the model maintains this balance, it reinforces that it is a neutral lithium atom.
By checking for these features—three protons, three electrons, and ideally three neutrons—you can ascertain that the model represents a neutral lithium atom.
