^Isotones

Are the atoms:

having same: n_n

But different: A, Z, n_e, n_p N_N

Examples:  1. ₁H² & ₂He³              2. ₁H³ & ₂He⁴

3. ₃Li⁷ & ₄Be⁸            4. ₁₇Cl³⁷ & ₁₉K³⁹

Symbols used: n_e = Number of electrons

n_p = Number of protons

n_n = Number of neutrons

N_N = Number of nucleons

A = Mass Number

Z = Atomic Number
