use the periodic table to determine which of the following could be an isotope of indium (in). check all that apply. z = 49, a = 113 n = 64, z = 49 n = 61, a = 113 a = 110, n = 49

use the periodic table to determine which of the following could be an isotope of indium (in). check all that apply. z = 49, a = 113 n = 64, z = 49 n = 61, a = 113 a = 110, n = 49

Answer

Explanation:

Step1: Recall the atomic number of indium

Indium (In) has an atomic number (Z = 49). Isotopes of an element have the same atomic number.

Step2: Use the formula (A=Z + N)

  • For (Z = 49,A = 113): Since (Z = 49) (matches indium's atomic number), this could be an isotope. Using (A=Z + N), we get (N=A - Z=113 - 49 = 64).
  • For (N = 64,Z = 49): (Z = 49) (correct atomic number for indium). Using (A=Z + N), (A=49+64 = 113).
  • For (N = 61,A = 113): Using (A=Z + N), (Z=A - N=113 - 61=52\neq49). So this is not an indium isotope.
  • For (A = 110,N = 49): Using (A=Z + N), (Z=A - N=110 - 49 = 61\neq49). So this is not an indium isotope.

Answer:

(Z = 49,A = 113) and (N = 64,Z = 49)
