Consider a metal ion with the outer electron configuration of d4d4. In a coordination complex, the number of unpaired electrons in that metal ion depends on the orientation and type of ligands that surround it. Classify each description of a complex by the number of unpaired electrons in the d4d4 metal ion. Drag the appropriate items to their respective bins.

explanation:

let the different atoms be x and y. each with four protons and same mass will be represented as follows.

mass number is number of protons + number of neutrons.

            and  

since, it is given that one has a negative charge while the other is neutral. therefore, there will be increase in number of protons and the atom will be represented as follows.

according to periodic table, mass number of beryllium is 9 and it has atomic number 4 so, the atoms will be and .  

the protons and neutrons will be located inside the nucleus whereas the electrons will be revolving around the nucleus.
