The answer is b. The answer is false.
The ionization energy is 1 × 10^-18 J
<h3>What is ionization energy?</h3>
The ionization energy is the energy required to remove an electron from an atom.
We have the following information;
wavelength of the photon = 58.4 nm
Speed of the electron = 2310 × 10^3 m/s
Since;
hv = I + 1/2mv^2
v = c/λ
hc/λ = I + 1/2mv^2
I = hc/λ - 1/2mv^2
I = (6.6 × 10^-34 × 3 × 10^8/58.4 × 10^-9) - (1/2 × 9.11 × 10^-31 × (2310 × 10^3)^2)
I = 1 × 10^-18 J

Answer:
From top to bottom down a group, electronegativity decreases. This is because atomic number increases down a group.
The ions are as follows;
- As2O3 - As^3+, O^2-
- MnS - Mn^2+, S^2-
- VCl3 - V^3+, Cl^-
- NiF2 - Ni^2+, F^-
<h3>What is a cation and an anion?</h3>
A cation is a positive ion while an anion is a negative ion. Ionic compounds are composed o cations and anions.
The anions and cations in the ionic compounds in the table are shown below;
- As2O3 - As^3+, O^2-
- MnS - Mn^2+, S^2-
- VCl3 - V^3+, Cl^-
