question 1 (mandatory) (1 point)\na $_{17}^{35}$cl atom has _________ protons, _________ neutrons, and _________ electrons.\na) 17; 18; 17\nb) 17; 35; 17\nc) 18; 35; 17\nd) 35; 17; 17\ne) 18; 17; 18
Answer
Explanation:
Step1: Identify proton number
The sub - script in the isotope notation $_{17}^{35}\text{Cl}$ represents the atomic number (Z), which is the number of protons. So, the number of protons is 17.
Step2: Calculate neutron number
The mass number (A) is the sum of protons and neutrons. Given A = 35 and Z = 17, the number of neutrons $n=A - Z=35 - 17 = 18$.
Step3: Determine electron number
In a neutral atom, the number of electrons is equal to the number of protons. Since it is a neutral chlorine atom and the number of protons is 17, the number of electrons is 17.
Answer:
A. 17; 18; 17
