Explanation:

Step1: Recall atomic - related concepts

The atomic number ($Z$) is equal to the number of protons. In a neutral atom, the number of electrons is equal to the number of protons. The mass number ($A$) is the sum of the number of protons and neutrons ($A = p + n$). The isotopic symbol notation is $_{Z}^{A}X$, where $X$ is the chemical symbol of the element.

Step2: First row (Carbon - 14)

Given: Protons = 6, Neutrons = 8, Electrons = 6 (since it's neutral), Mass number = 14 (6 + 8), Atomic number = 6 (same as protons), Isotopic symbol notation $_{6}^{14}C$.

Step3: Second row

Protons = 18, Neutrons = 19, Electrons = 18 (neutral atom), Mass number = 18+19 = 37, Atomic number = 18, Isotopic symbol notation $_{18}^{37}Ar$.

Step4: Third row

Protons = 23, Neutrons = 25, Electrons = 23 (neutral atom), Mass number = 23 + 25=48, Atomic number = 23, Isotopic symbol notation $_{23}^{48}V$.

Step5: Fourth row

Protons = 35, Neutrons = 46, Electrons = 35 (neutral atom), Mass number = 35 + 46 = 81, Atomic number = 35, Isotopic symbol notation $_{35}^{81}Br$.

Step6: Fifth row

Protons = 37, Neutrons = 37, Electrons = 37 (neutral atom), Mass number = 37+37 = 74, Atomic number = 37, Isotopic symbol notation $_{37}^{74}Rb$.

Step7: Sixth row

Electrons = 17, so Protons = 17 (neutral atom), Atomic number = 17. Let the mass number be $A$. If we assume a common isotope of chlorine, $_{17}^{35}Cl$ has 18 neutrons ($35-17$). Mass number = 35, Neutrons = 18, Isotopic symbol notation $_{17}^{35}Cl$.

Step8: Seventh row

Protons = 20, Neutrons = 21, Electrons = 20 (neutral atom), Mass number = 20 + 21=41, Atomic number = 20, Isotopic symbol notation $_{20}^{41}Ca$.

Answer:

Isotope name notation	Protons	Neutrons	Electrons	Mass number	Atomic number	Isotopic Symbol notation
Argon - 37	18	19	18	37	18	$_{18}^{37}Ar$
Vanadium - 48	23	25	23	48	23	$_{23}^{48}V$
Bromine - 81	35	46	35	81	35	$_{35}^{81}Br$
Rubidium - 74	37	37	37	74	37	$_{37}^{74}Rb$
Chlorine - 35	17	18	17	35	17	$_{17}^{35}Cl$
Calcium - 41	20	21	20	41	20	$_{20}^{41}Ca$
