The chart above is based on the energy it takes to remove an electron from a particular atom. The more energy it takes to remove an electron, the closer that electron is to the nucleus. The graph separates the electrons based on their sublevels. Answer the following questions based on the Photoelectric Spectrum Chart.

1. The electron configuration for this element is

2. The noble gas notation for this element is

3. If this element was found to have 16 neutrons, it would have the isotope symbol . Use the keyboard symbol below for the mass number and atomic number.
