Question

4 ccc scale, proportion, and quantity identify the number of protons and electrons in fluorine and iodine. the element fluorine helps prevent tooth decay and is found in many toothpastes. atomic number: 9 notebook fluorine has an atomic number of 9. the number of protons in fluorine is 9. saved 09/28/2025 6:40pm edit the element iodine is often used to clean skin before surgery. atomic number: 53 notebook

Explanation:

Step1: Recall atomic - number rule

The number of protons in an atom is equal to its atomic number. Also, in a neutral atom, the number of electrons is equal to the number of protons.

Step2: Determine protons and electrons for fluorine

For fluorine with atomic number 9, the number of protons is 9. Since it is neutral, the number of electrons is also 9.

Step3: Determine protons and electrons for iodine

For iodine with atomic number 53, the number of protons is 53. Since it is neutral, the number of electrons is also 53.

Answer:

Fluorine: Protons = 9, Electrons = 9; Iodine: Protons = 53, Electrons = 53
