Answer:

The answer is "The number of protons is given by the atomic number, which increases by one moving from left to right across each row of the periodic table."

Step-by-step explanation:

If you look at the periodic table, the elements atomic numbers increase from left to right by one. Therefore, the protons also increase by one from left to right because the number of protons in an element is the same as the atomic number.
