Question

types of atoms
atomic number an element is the simplest form of matter that has a unique set of properties. the number of protons in the nucleus of an atom is called an elements atomic number. the atomic number of an atom is what makes one element different from another. for example, carbon has 6 protons and has an atomic number of 6.
atoms are electrically neutral particles because they have no net charge.
● therefore, for an atom to be neutral, the number of protons (positively charged particles) must be equal the number of electrons (negatively charged particles).
helium the element helium is less dense than air, so it is used in balloons.
atomic number: 2
number of protons: 2
number of electrons: 2
silver the element silver is reflective and resists corrosion, so it is often used in jewelry.
atomic number: 47
number of protons: 47
number of electrons: 47
10 ccc scale, proportion, and quantity identify the numbers of protons and electrons in fluorine and iodine.
the element fluorine helps prevent tooth decay and is found in many toothpastes.
atomic number: 9
number of protons:................
number of electrons:................
the element iodine is often used to clean skin before surgery.
atomic number: 53
number of protons:................
number of electrons:................

Explanation:

Step1: Recall the relationship

The number of protons is equal to the atomic number, and for a neutral atom, the number of electrons is equal to the number of protons.

Step2: Calculate for fluorine

For fluorine with atomic number 9, number of protons = 9, number of electrons = 9.

Step3: Calculate for iodine

For iodine with atomic number 53, number of protons = 53, number of electrons = 53.

Answer:

Fluorine:
Number of protons: 9
Number of electrons: 9
Iodine:
Number of protons: 53
Number of electrons: 53
