Write the chemical symbols for three different atoms or atomic cations with 26 electrons.

The chemical symbols for three different atoms or atomic cations with 26 electrons are Fe, ,

Explanation:

The atomic number of an atom is equal to the number of protonsAn atom is neutral, it has an equal number of electrons and protons.Element with atomic number 26 is Iron, Fe.A neutral atom of iron has an equal number of protons and electrons.Cobalt has an atomic number of 27.A neutral atom of cobalt has an equal number of protons and electrons.Cobalt has 27 electrons and by losing one electron it will form a cobalt (I) ion with 26 electrons.The cobalt (I) ion has 26 electrons, .Nickel has an atomic number of 28.A neutral atom of nickel has an equal number of protons and electrons.Nickel has 28 electrons and by losing two electrons it will form a nickel(II) ion with 26 electrons.The nickel (II) ion has 26 electrons,.

So, from this, we can write chemical symbols for three different atoms or atomic cations with 26 electrons are Fe, , .

A neutral iron atom (Fe)

Mn-1 (a manganese that has gained one electron)

Co+1 (a cobalt that has lost on electrons)

All three of these atoms/ions are isoelectronic, meaning that they all have the same number of electrons!
