The ion that is most likely to form is $\boxed{{{\text{N}}^{3-}}{\text{ ion}}}$ .

Further explanation:

Octet rule:

Lewis structure for any atom or molecule depicts the valence electrons as dots around the element’s symbol present in the molecule along with the bonds that connect them. Every element tries to complete an octet except the hydrogen atom. Every element in the Lewis structure tries to attain eight electrons in its valence shell by transfer or share of electrons. This rule is known as the octet rule. It only applied on main s and p subshells and not applied on d and f subshells.

1. The electronic configuration of ${\text{M}}{{\text{n}}^{3+}}$ ion,

$\left[{{\text{Ar}}}\right]3{d^4}$

Since ${\text{M}}{{\text{n}}^{3+}}$ ion has no fully-filled d-orbital thus it is not most likely to form.

2. The electronic configuration of ${{\text{N}}^{3-}}$ ions,

$\left[{{\text{He}}}\right]2{s^2}2{p^6}$

Since ${{\text{N}}^{3-}}$ ion has eight electrons in its valence shell and it is fully filled, therefore, it follows the octet rule, and it is most likely to form.

3. The electronic configuration of ${\text{Z}}{{\text{n}}^{4+}}$ ion, $\left[{{\text{Ar}}}\right]3{d^8}$

The ${\text{Z}}{{\text{n}}^{4+}}$ ion has no fully-filled d-orbital, and thus it is not most likely to form.

4. The electronic configuration of ${\text{L}}{{\text{i}}^{2+}}$ ion,

$1{s^1}$

The ${\text{L}}{{\text{i}}^{2+}}$ has no fully-filled s-orbital, and also it does not follow octet rule. Thus it is not most likely to form.

5. The electronic configuration of ${{\text{K}}^-}$ ion,

$\left[{{\text{Ar}}}\right]4{s^2}$

The ${{\text{K}}^-}$ ion does not have eight electrons in its valence shell, and thus it is not most likely to form.

Answer from: Quest

1.consider the following balanced equation and answer parts a through. show calculations for each part.

3 ag(s) + 4 hno3(aq) → 3 agno3(aq) + no(g) + 2 h2o(l)

a. calculate the number of moles of agno3 produced by the reaction of 3 moles of ag with excess hno3. if the number to the left of the compound represents the number of moles of the compound which are present, then 3 moles of ag react with 4 moles hno3 to produce 3 moles agno3 (aq).

so the answer to a would be 3 moles.

b. calculate the number of moles of agno3 produced by the reaction of 108 grams of ag with excess hno3.

i'm not sure how to plug in the grams of silver into an equation using moles to find how many moles are produced.

c. calculate the number of grams of agno3 produced by the reaction of 108 grams of ag with excess hno3

d. calculate the number of moles of no produced as a byproduct of the reaction of 108 grams of ag with excess hno3.

e. calculate the number of grams of no produced as a byproduct starting with 108 grams of ag and excess hno3.
