Question

16 s 32.06 atomic # = \underline{16} mass = \underline{\quad} # of protons = \underline{16} # of neutrons = \underline{16} # of electrons = \underline{16}

Explanation:

Step1: Determine Atomic Number

The atomic number (Atomic #) of an element is equal to the number of protons, and it's also the top number in the element's symbol box (here, 16 for S).
Atomic # = 16

Step2: Determine Atomic Mass

The atomic mass is the bottom number in the element's symbol box, which is 32.06 for S.
Mass = 32.06

Step3: Determine Number of Protons

Number of protons equals atomic number.

of Protons = 16

Step4: Determine Number of Neutrons

Neutrons = Atomic Mass (rounded to whole number) - Atomic Number. Rounded atomic mass of S is 32. So, 32 - 16 = 16.

of Neutrons = 16

Step5: Determine Number of Electrons

In a neutral atom, number of electrons equals number of protons.

of Electrons = 16

Answer:

Atomic # = 16
Mass = 32.06

of Protons = 16

of Neutrons = 16

of Electrons = 16
