Question

1. chlorine - 35 is an isotope of chlorine that has 17 protons and 18 neutrons in the nucleus. how would you write the nuclear notation?

Explanation:

Step1: Recall nuclear notation rules

Nuclear notation is written as $_{Z}^{A}X$, where $Z$ is the atomic number (number of protons) and $A$ is the mass - number (sum of protons and neutrons).

Step2: Identify atomic number and mass - number

Chlorine has an atomic number $Z = 17$ (given by the number of protons). The mass - number $A=17 + 18=35$ (sum of 17 protons and 18 neutrons).

Step3: Write the nuclear notation

The nuclear notation for this chlorine isotope is $_{17}^{35}Cl$.

Answer:

$_{17}^{35}Cl$
