Question

#4.

4. Use the atomic model above to answer the following questions: 1 pt for each blank




a. How many protons?

b. How many neutrons?

c. What is the name of this atom?

Answer 1

A → 16 protons

B → 16 neutrons

C → Sulfur

Step-by-step explanation:

Remember, in a neutral atom the amount of protons is the same as the number of electrons. In the picture provided, its shown that there are 16 electrons which means there are 16 protons. Finding the amount of neutrons will be more tricky. The valence electron count will allow us to find this. The valence electrons will allows us to determine where it is on the periodic table (So does atomic number). The valence electron count is 6. So, using the current information (6 valence electrons and atomic number of 16) we can look at the periodic table and pinpoint which element it is. As you look, you'll find that the element sulfur matches the information. Since the element is sulfur, and it has an atomic mass of 32, we can subtract the atomic number from the atomic mass to find the amount of neutrons.

32 - 16 = 16

Thus, the atom in the picture is sulfur with an atomic number of 16, atomic mass of 32, and an electron count of 6.
