There is no isoelectronic elements. However, there is isoelectronic ions.

Isoelectronic means: "Same number of electrons". Therefore, same number of protons, therefore, same atomic number, thus, there is no isoelectronic elements.

However, there is isoelectronic ions, such as: Na^+, Mg^(2+), F^(-), O^(2-) and N^(3-)Na+,Mg2+,F,O2andN3. All these ions have 10" electrons"10 electrons, therefore, they are called isoelectronic ions .
