13 which statement is correct for the ion with the nuclear symbol * (0.5 points) it has 18 protons and 18 electrons. it has 17 neutrons and 18 electrons. it has 18 neutrons and 18 electrons. it has 17 protons and 17 electrons.

13 which statement is correct for the ion with the nuclear symbol * (0.5 points) it has 18 protons and 18 electrons. it has 17 neutrons and 18 electrons. it has 18 neutrons and 18 electrons. it has 17 protons and 17 electrons.

Answer

Explanation:

Step1: Identify proton number

The sub - script in the nuclear symbol $_{17}^{35}Cl^-$ represents the atomic number (number of protons). So, the number of protons is 17.

Step2: Determine electron number

The ion is $Cl^-$, which means it has gained one electron. A neutral chlorine atom has 17 electrons, so the $Cl^-$ ion has 17 + 1=18 electrons.

Step3: Calculate neutron number

The mass number (sup - script) is 35. The number of neutrons $n$ is calculated by $n = mass\ number - atomic\ number$. So, $n=35 - 17 = 18$ neutrons.

Answer:

It has 18 neutrons and 18 electrons.
