Question

Match each species and orbit in Column I with the statements in Column II that are true for it $(r_{1}$ of $H = 0.529$ Å, $v_{1}$ of $H = 2.18 \times 1 0^{6} m / s, E_{1}$ of $H = - 13.6 e V) (a$ Column I entry may match more than one Column II entry):

Column I (Species, orbit)	Column II (Statement)
(P) $H e^{+}, n = 2$	(1) radius = 1.058 Å
(Q) $L i^{2 +}, n = 3$	(2) radius = 2.116 Å
(R) H, $n = 2$	(3) speed = $2.18 \times 1 0^{6} m / s$
(S) $B e^{3 +}, n = 4$	(4) speed = $1.09 \times 1 0^{6} m / s$
	(5) energy = -13.6 eV
	(6) energy = -3.4 eV

r = 0.529 n 2 / Z Å, v = 2.18 × 1 0 6 Z / nm / s , E = − 13.6 Z 2 / n 2 eV. (P) r = 0.529 × 4/2 = 1.058 Å (1); Z / n = 1 so v = 2.18 × 1 0 6 (3); E = − 13.6 (5). (Q) r = 0.529 × 9/3 = 1.587 Å (none); Z / n = 1 (3); E = − 13.6 (5). (R) r = 2.116 Å (2); v = 1.09 × 1 0 6 (4); E = − 3.4 eV (6). (S) r = 0.529 × 16/4 = 2.116 Å (2); Z / n = 1 (3); E = − 13.6 eV (5). Correct matching: P to 1,3,5; Q to 3,5; R to 2,4,6; S to 2,3,5. Answer: (B).
