The electronic configuration of X is 2,8,6. It gains 'Y’ electrons into its valence shell to attain the nearest noble gas electronic configuration and gets converted to an ion Z. X, Y, and Z, respectively, are:
- Sodium, one, electropositive
- Beryllium, two, electronegative
- Oxygen, six, electronegative
- Sulphur, two, electronegative

Answer
Sulphur, two, electronegative
Reason — X has electronic configuration 2, 8, 6. The molecule has total 16 electrons, So, the atomic number is 16. Hence, the element X is Sulphur (S). To achieve the nearest nobel gas configuration of argon(2,8,8), sulphur will gain two electrons. So, Y is 2. Gaining of electrons forms a negative ion. Thus, sulphur will be electronegative.
