QuestionDetermine the number of protons, electrons, and neutrons in ${ }^{35} \mathrm{Cl}^{-}$ .

Studdy Solution

STEP 1

Assumptions1. The given isotope is ${ }^{35} \mathrm{Cl}^{-}$ . The superscript (35) represents the atomic mass number (the sum of protons and neutrons)
3. The symbol (Cl) represents the chemical element, in this case, Chlorine, which has an atomic number of17 (number of protons)
4. The minus sign (-) indicates that the ion has one extra electron than protons

STEP 2

The number of protons in an atom is equal to the atomic number of the element. For Chlorine (Cl), the atomic number is17.
$\#protons = Atomic\, number$

STEP 3

Now, plug in the atomic number of Chlorine to calculate the number of protons.
$\#protons =17$

STEP 4

The ion ${ }^{35} \mathrm{Cl}^{-}$ has one extra electron than protons because of its negative charge. Therefore, the number of electrons is the number of protons plus one.
$\#electrons = \#protons +1$

STEP 5

Now, plug in the number of protons to calculate the number of electrons.
$\#electrons =17 +1$

STEP 6

Calculate the number of electrons.
$\#electrons =17 +1 =18$

STEP 7

The atomic mass number is the sum of protons and neutrons. Therefore, we can find the number of neutrons by subtracting the number of protons from the atomic mass number.
$\#neutrons = Atomic\, mass\, number - \#protons$

STEP 8

Now, plug in the atomic mass number (35) and the number of protons (17) to calculate the number of neutrons.
$\#neutrons =35 -17$

STEP 9

Calculate the number of neutrons.
$\#neutrons =35 -17 =18$ The ${ }^{35} \mathrm{Cl}^{-}$ ion has17 protons,18 electrons, and18 neutrons.

STEP 1

STEP 2

The number of protons in an atom is equal to the atomic number of the element. For Chlorine (Cl), the atomic number is17.#protons=Atomic number\#protons = Atomic\, number#protons=Atomicnumber

STEP 3

Now, plug in the atomic number of Chlorine to calculate the number of protons.#protons=17\#protons =17#protons=17

STEP 4

The ion 35Cl−{ }^{35} \mathrm{Cl}^{-}35Cl− has one extra electron than protons because of its negative charge. Therefore, the number of electrons is the number of protons plus one.#electrons=#protons+1\#electrons = \#protons +1#electrons=#protons+1

STEP 5

Now, plug in the number of protons to calculate the number of electrons.#electrons=17+1\#electrons =17 +1#electrons=17+1

STEP 6

Calculate the number of electrons.#electrons=17+1=18\#electrons =17 +1 =18#electrons=17+1=18

STEP 7

The atomic mass number is the sum of protons and neutrons. Therefore, we can find the number of neutrons by subtracting the number of protons from the atomic mass number.#neutrons=Atomic mass number−#protons\#neutrons = Atomic\, mass\, number - \#protons#neutrons=Atomicmassnumber−#protons

STEP 8

Now, plug in the atomic mass number (35) and the number of protons (17) to calculate the number of neutrons.#neutrons=35−17\#neutrons =35 -17#neutrons=35−17

STEP 9

Calculate the number of neutrons.#neutrons=35−17=18\#neutrons =35 -17 =18#neutrons=35−17=18The 35Cl−{ }^{35} \mathrm{Cl}^{-}35Cl− ion has17 protons,18 electrons, and18 neutrons.
