Determine how many subatomic particles are in the following days

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

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

why do the isotopes of a particular element behave differently in nuclear reactions but the same in chemical reactions? chemical reactions involve changes to electrons in an atom; isotopes do not differ in electrons, and so they react the same way during chemical changes.
