Answer

Explanation:

Step1: Recall atomic - related concepts

For a neutral atom in the ground state, the number of electrons ((e^-)) is equal to the number of protons ((P^+)), and the mass number ((A)) is the sum of the number of protons and neutrons ((N)). The atomic number ((Z)) is equal to the number of protons.

Step2: First table (left - top)

Given (N = 17) and (P^+=25). For a neutral atom, (e^-=P^+=25). The mass number (A = P^++N=25 + 17=42). The element with (P^+=25) is manganese. The isotope name is Manganese - 42. For the second isotope in the first box, if (N = 15) and (P^+=25), then (e^-=25) and the mass number (A=25 + 15 = 40), isotope name is Manganese - 40.

Step3: Second table (right - top)

Given (e^- = 6) and (P^+=6), then (N) can be calculated from the isotope name convention. If the isotope name is not given directly, assume we are dealing with carbon (since (P^+=6)). For a neutral carbon atom with (e^- = 6) and (P^+=6). If the first isotope has (e^-=6) and (P^+=6), and assume mass number (A_1) and (A_2) from the given data. If (e^- = 6) and (P^+=6), for a neutral atom it is carbon. If (N_1) and (N_2) are the number of neutrons. We know (A=P^++N). For the first carbon isotope, if (e^-=6) and (P^+=6), assume mass number (A_1) is not given directly. For the second carbon isotope, if (e^- = 6) and (P^+=6), and (N_2) is related to the mass - number. Since (P^+=6), the element is carbon. If (e^-=6) and (P^+=6), for a neutral atom, and if we assume the mass numbers from the context of isotopes, if (N_1) and (N_2) are the number of neutrons, (A_1=P^++N_1) and (A_2=P^++N_2).

Step4: Third table (left - bottom)

For iron, the atomic number of iron (Z = 26). For Iron - (x) isotopes, (P^+=26) for both. For the first isotope with (N = 27), (e^-=26) (neutral atom) and mass number (A_1=26 + 27=53), isotope name is Iron - 53. For the second isotope with (N = 30), (e^-=26) and mass number (A_2=26+30 = 56), isotope name is Iron - 56.

Step5: Fourth table (right - bottom)

Given (P^+=24), the element is chromium. For a neutral atom, (e^-=24). For the first isotope with mass number (A_1 = 54), (N_1=A_1 - P^+=54 - 24=30). For the second isotope with mass number (A_2 = 56), (N_2=A_2 - P^+=56 - 24=32).

Step6: Fifth table (question 4)

For Chromium - 50: The atomic number of chromium (Z = 24), so (P^+=24). For a neutral atom, (e^-=24). The mass number (A = 50), and (N=A - P^+=50 - 24=26). The full nuclear notation is (_ {24}^{50}Cr). For the second isotope, given (P^+=14), the element is silicon. The atomic number (Z = 14), for a neutral atom (e^-=14). Given (N = 17), the mass number (A=P^++N=14 + 17=31). The isotope name is Silicon - 31, and the full nuclear notation is (_ {14}^{31}Si).
