Answer:
C. Fluorine because the model has 9 protons which is represented by the atomic number
Explanation:
We usually identify an element by the number of protons in them. The number of protons is the atomic number of an atom.
- Every atom has a specific number of protons in them.
- This number of protons is the atomic number.
- According to the periodic law, atoms are arranged on the periodic table based on their atomic number.
- The given fluorine atom has 9 protons which represents the atomic number of the atom.
- This way, the given number clearly shows the right model for identifying the chemical specie.
To find the number of neutrons, subtract the number of protons from the mass number. number of neutrons=40−19=21.

Albert Einstein was responsible for the general theory of relativity. The general theory of relativity explains that what we recognize as the force of gravity in fact arises from the curvature of space and time.
In the latency of matter and energy it can evolve, stretch and morph. Forming ridges, valleys and mountains that cause bodies moving through it to curve and zig-zag.
