1.what happens to the outermost electron in a sodium atom when the atom is heated and made to give off a line spectrum?
2.how did observations of spectra lead to conclusions that the energy given off by excited atoms is quantized?
3.Explain how atoms can be electrically neutral even though they contain charged particles? Is dthe answer to this question because they balance or level each other out.

1. The outermost electron is excited to higher energy levels by heating. When it falls back to a lower level, it emits energy in the form of a photon of light.
2. You know the energy is quantized because you produce a line spectrum and not a continuous spectrum. If the energy was continuous, you'd see a continuous spectrum.
3. Yes, the number of protons and electrons is always equal in a neutral atom.

1. It leaves out its shell to get ionized.
2. Don't know the answer!
3. The no. of electrons and protons are equal in an atom so they
canceled their charges with each other..!
