Answer 1

Symbol	Ion Formed	Number of Electrons in Ion	Number of protons in Ion
F	F-	10	9
Te	Te4+	48	52
I	I-	54	53
Mg	Mg2+	10	12

Explanation :-

Symbol of the atom is : _ZX^A

A = Atomic mass and Z = Atomic number

Number of protons (p) = Atomic number (Z)

Number of electrons (e) = Number of protons (p) for neutral atom

(a). The most common oxidation state of F is -1, therefore F ion is : F^-

Symbol = ₉F¹⁹ , Number of protons = 9 , Number of electrons in F^- = 9 + 1= 10

(b). The most common oxidation state of Te is +4, therefore Te ion is : Te⁴⁺

Symbol = ₅₂Te^127.6 , Number of p = 52 , Number of electrons in Te⁴⁺ = 52-4 = 48

(c). The most common oxidation state of I is -1, therefore I ion is : I^-

Symbol =₅₃I^126.9 , Number of protons = 53 , Number of electrons in I^- = 53 + 1= 54

(d). The most common oxidation state of Mg is +2, therefore Mg ion is : Mg²⁺

Symbol = ₁₂Mg²⁴ , Number of protons = 12 , Number of electrons in Mg²⁺ = 12-2 = 10
