Question

question 2. the three isotopes of oxygen are oxygen - 16, oxygen - 17, and oxygen - 18. for each isotope, provide the nuclear notation that includes both the atomic number and mass number. additionally, indicate the number of protons, neutrons, and electrons present in each isotope.
oxygen - 16
nuclear notation:
number of protons:
number of electrons:
number of neutrons:
oxygen - 17
nuclear notation:
number of protons:
number of electrons:
number of neutrons:
oxygen - 18
nuclear notation:
number of protons:
number of electrons:
number of neutrons:

Explanation:

Step1: Recall atomic number and mass - number concepts

The atomic number ($Z$) of oxygen is 8. The mass number ($A$) is given in the isotope name. For a neutral atom, the number of electrons = number of protons = atomic number. The number of neutrons $N=A - Z$. The nuclear notation is $_{Z}^{A}X$, where $X$ is the chemical symbol.

Step2: For Oxygen - 16

The mass number $A = 16$, atomic number $Z = 8$.
Number of Protons: 8 (since atomic number of oxygen is 8).
Number of Electrons: 8 (for a neutral atom, electrons = protons).
Number of Neutrons: $N=A - Z=16 - 8 = 8$.
Nuclear Notation: $_{8}^{16}O$.

Step3: For Oxygen - 17

The mass number $A = 17$, atomic number $Z = 8$.
Number of Protons: 8.
Number of Electrons: 8.
Number of Neutrons: $N=A - Z=17 - 8 = 9$.
Nuclear Notation: $_{8}^{17}O$.

Step4: For Oxygen - 18

The mass number $A = 18$, atomic number $Z = 8$.
Number of Protons: 8.
Number of Electrons: 8.
Number of Neutrons: $N=A - Z=18 - 8 = 10$.
Nuclear Notation: $_{8}^{18}O$.

Answer:

Isotope	Number of Protons	Number of Electrons	Number of Neutrons	Nuclear Notation
Oxygen - 17	8	8	9	$_{8}^{17}O$
Oxygen - 18	8	8	10	$_{8}^{18}O$
