Answer:
Number of protons in Na²⁴ = 11
Number of neutrons in Na²⁴ = 13
Number of electrons in Na²⁴ = 11
Number of protons in I¹³¹ = 53
Number of neutrons in I¹³¹ = 78
Number of electrons in I¹³¹ = 53
Step-by-step explanation:
Sodium is present in group one.
Atomic number of sodium is 11.
Its atomic mass is 23 amu.
Electronic configuration:
Na₁₁ = 1s² 2s² 2p⁶ 3s¹
Number of protons in Na²⁴ = 11
Number of neutrons in Na²⁴ = 13 (24-11= 13)
Number of electrons in Na²⁴ = 11
Iodine:
Iodine is halogen element.
Its atomic number is 53.
Its atomic mass is 127 amu.
Electronic configuration:
I₅₃= [Kr] 4d¹⁰ 5s² 5p⁵
Number of protons in I¹³¹ = 53
Number of neutrons in I¹³¹ = 78 (131-53= 78)
Number of electrons in I¹³¹ = 53
