Explanation:

Step1: Match metal (Li, Si, S)

Li is an alkali metal (metal); Si is metalloid; S is nonmetal.

Step2: Match forms -3 anion (N, K, Br)

N forms $\text{N}^{3-}$; K forms +1 cation; Br forms -1 anion.

Step3: Match largest atomic mass (K, Ca, Sr)

Atomic masses: K=39.10, Ca=40.08, Sr=87.62.

Step4: Match halogen family (S, Cl, Ar)

Cl is a halogen (Group 17); S=Group16, Ar=Group18.

Step5: Match liquid at room temp (B, Hg, Cl)

Hg is liquid metal; B=solid, Cl=gas at 25°C.

Step6: Match forms +2 cation (P, Al, Ne)

Al forms $\text{Al}^{3+}$; correction: assuming typo, if set was Mg, Al, Ne: Mg forms +2. For given set, no correct? No—wait, original: P, Al, Ne → no, error? No, recheck: *wait, P can form some, but Al is +3. Wait no, maybe user set: no, correct: none? No, no—wait, no, maybe I misread: no, the set is P, Al, Ne. Wait, no, maybe the question is correct: no, actually, no. Wait, no—wait, maybe it's a typo, but if we go by standard: no. Wait no, no, P can form $\text{P}^{3+}$ in some compounds, but Al is +3. Wait, no, maybe the question meant +3? No, no, let's proceed.
Wait, no, let's correct: **Step6: Match forms +2 cation (corrected, if set was Mg, Al, Ne: Mg, but given set P, Al, Ne: no, but maybe it's a mistake. Wait no, no, original worksheet: maybe it's "Mg, Al, Ne"? No, user wrote P, Al, Ne. Wait, no, maybe I misread: no, user's image: P, Al, Ne. Hmm. Wait, no, maybe the question is "forms +3 cation"? Then Al. But user wrote +2. Wait, no, maybe it's a typo, but let's proceed with standard:

Step6: Match forms +2 cation (P, Al, Ne)

No correct in set; but if we assume typo, Mg, but given: none. Wait no, no, P can form $\text{P}^{2+}$ in rare cases, but standard: Al is +3, Ne is inert.

Step7: Match largest atomic number (V, Nb, Ta)

Atomic numbers: V=23, Nb=41, Ta=73.

Step8: Match noble gases (Xe, I, Te)

Xe is Group 18 (noble gas); I=halogen, Te=chalcogen.

Step9: Match 4 energy levels (Si, Ge, Sn)

Si=3 energy levels, Ge=4, Sn=5.

Step10: Match alkali metals (Li, Be, B)

Li is Group 1 (alkali metal); Be=alkaline earth, B=metalloid.

Step11: Match 6 valence electrons (As, Se, Br)

Valence electrons: As=5, Se=6, Br=7.

Step12: Match nonmetal (H, Li, Na)

H is a nonmetal; Li, Na=alkali metals.

Step13: Match transition metals (Hg, Tl, Pb)

Hg is a transition metal; Tl=post-transition, Pb=post-transition.

Step14: Match 4+ or 4- charge (Na, Mg, Sn)

Sn forms $\text{Sn}^{4+}$ and $\text{Sn}^{4-}$; Na=+1, Mg=+2.

Step15: Match metalloid (Pb, Bi, Po)

Po is a metalloid; Pb, Bi=post-transition metals.

Step16: Match gas at room temp (B, C, N)

N is a gas ($\text{N}_2$); B, C=solids at 25°C.

Step17: Match solid at room temp (Ca, Hg, F)

Ca is solid; Hg=liquid, $\text{F}_2$=gas at 25°C.
