You have a sample of fluorine to analyze. The sample is made up of neutral atoms. Using the information in the diagram at the right, determine the number of protons, neutrons, and electrons found in each atom of your sample. Explain your answer. The diagram:
Fluorine - 19
Atomic Number - 9
Atomic Mass - 19

since the atomic number is the number of protons in the nucleus, as we move to the left on the periodic table, the electrostatic pull between the nucleus and the valence electron shell decreases. as we move down a group (vertical column), the valence shell energy level gets further and further from the nucleus.

2b2t

explanation:

2b2t

c. orbital shape i hope this is correct
