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.

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 atomic number and mass number

In the nuclear symbol $^{35}_{17}\text{Cl}^{-}$, the bottom - number (17) is the atomic number (Z) which represents the number of protons. So, the number of protons is 17.

Step2: Determine number of neutrons

The top - number (35) is the mass number (A). The mass number is the sum of protons and neutrons ($A = Z+N$). So, the number of neutrons $N=A - Z=35 - 17 = 18$.

Step3: Determine number of electrons

The ion is $\text{Cl}^{-}$, which means it has gained 1 electron. A neutral chlorine atom has the same number of electrons as protons (17). So, the $\text{Cl}^{-}$ ion has $17 + 1=18$ electrons.

Answer:

It has 18 neutrons and 18 electrons.
