H₃⁺ +  = (H₃⁺ • )

By formula: H₃⁺ + Ar = (H₃⁺ • Ar)

(H₃⁺ • ) +  = (H₃⁺ • 2)

By formula: (H₃⁺ • Ar) + Ar = (H₃⁺ • 2Ar)

(H₃⁺ • 2) +  = (H₃⁺ • 3)

By formula: (H₃⁺ • 2Ar) + Ar = (H₃⁺ • 3Ar)

(H₃⁺ • 3) +  = (H₃⁺ • 4)

By formula: (H₃⁺ • 3Ar) + Ar = (H₃⁺ • 4Ar)

(H₃⁺ • 4) +  = (H₃⁺ • 5)

By formula: (H₃⁺ • 4Ar) + Ar = (H₃⁺ • 5Ar)

(H₃⁺ • 5) +  = (H₃⁺ • 6)

By formula: (H₃⁺ • 5Ar) + Ar = (H₃⁺ • 6Ar)

(H₃⁺ • 6) +  = (H₃⁺ • 7)

By formula: (H₃⁺ • 6Ar) + Ar = (H₃⁺ • 7Ar)

H₃⁺ +  = (H₃⁺ • )

By formula: H₃⁺ + H₂ = (H₃⁺ • H₂)

(H₃⁺ • ) +  = (H₃⁺ • 2)

By formula: (H₃⁺ • H₂) + H₂ = (H₃⁺ • 2H₂)

(H₃⁺ • 2) +  = (H₃⁺ • 3)

By formula: (H₃⁺ • 2H₂) + H₂ = (H₃⁺ • 3H₂)

(H₃⁺ • 3) +  = (H₃⁺ • 4)

By formula: (H₃⁺ • 3H₂) + H₂ = (H₃⁺ • 4H₂)
