Explanation:

Step1: Recall Isotope Basics

For an isotope \(\ce{_Z^A X}\), \(Z\) = atomic number (protons), \(A\) = atomic mass, electrons = protons (neutral), neutrons = \(A - Z\).

Step2: Analyze \(\ce{_{22}^{47}Ti}\)

• Atomic number (\(Z\)) = 22 (protons, electrons).
• Atomic mass (\(A\)) = 47.
• Neutrons = \(47 - 22 = 25\).

Step3: Second Row (Atomic Mass 65, Neutrons 36)

• Protons (\(Z\)) = \(65 - 36 = 29\) (Copper, \(\ce{Cu}\)).
• Atomic number = 29, electrons = 29, nuclide: \(\ce{_{29}^{65}Cu}\).

Step4: Third Row (Protons 42, Neutrons 58)

• Atomic mass = \(42 + 58 = 100\) (Molybdenum, \(\ce{Mo}\)).
• Nuclide: \(\ce{_{42}^{100}Mo}\), electrons = 42.

Step5: Mendelevium-257 (\(\ce{Md}\))

• Mendelevium atomic number = 101 (protons, electrons).
• Neutrons = \(257 - 101 = 156\).
• Nuclide: \(\ce{_{101}^{257}Md}\).

Filled Table (Key Cells):

Element	Nuclide Symbol	Atomic Number	Atomic Mass	Electrons	Protons	Neutrons

Molybdenum	\(\ce{_{42}^{100}Mo}\)	42	100	42	42	58
Mendelevium	\(\ce{_{101}^{257}Md}\)	101	257	101	101	156

Answer:

Filled table as above (key values: \(\ce{_{22}^{47}Ti}\): 22, 47, 22, 22, 25; \(\ce{_{29}^{65}Cu}\): 29, 65, 29, 29, 36; \(\ce{_{42}^{100}Mo}\): 42, 100, 42, 42, 58; \(\ce{_{101}^{257}Md}\): 101, 257, 101, 101, 156).
