QuestionDetermine the number of protons and electrons in the ion $HSO_{3}^{-}$ .

Studdy Solution

STEP 1

Assumptions1. The polyatomic ion is $\mathrm{HS}_{3}^{-}$ . . The number of protons is equal to the atomic number of each atom in the ion.
3. The number of electrons is equal to the number of protons plus the charge of the ion.
4. The atomic number of Hydrogen (H) is1.
5. The atomic number ofulfur () is16.
6. The atomic number of Oxygen () is8.

STEP 2

First, we need to find the total number of protons in the ion. We can do this by adding the atomic numbers of each atom in the ion.
$Protons = Atomic\, number\, of\, H + Atomic\, number\, of\, + \times Atomic\, number\, of\, O$

STEP 3

Now, plug in the atomic numbers for Hydrogen,ulfur, and Oxygen to calculate the number of protons.
$Protons =1 +16 +3 \times8$

STEP 4

Calculate the number of protons.
$Protons =1 +16 +3 \times8 =33$

STEP 5

Now that we have the number of protons, we can find the number of electrons. The number of electrons is equal to the number of protons plus the charge of the ion.
$Electrons = Protons + Charge\, of\, the\, ion$

STEP 6

Plug in the values for the number of protons and the charge of the ion to calculate the number of electrons.
$Electrons =33 + (-1)$

STEP 7

Calculate the number of electrons.
$Electrons =33 + (-1) =32$ The polyatomic ion $\mathrm{HS}_{3}^{-}$ has33 protons and32 electrons.
