abbreviated electron configuration = e.c.
Solutions are mixtures of one or more solutes dissolved in a solvent. They do not have electron configurations. Only atoms and ions have electron configurations.
The externall shell of electrons is completely filled.

The atomic number of zinc is 30. Its abbreviated electron configuration is [Ar]4s23d10 The full electron configuration is 1s22s22p63s23p64s23d10 (configurations for the atom in its ground state. Ions and excited atoms have different configurations).
All of the representative elements (s and p block) have predictable electron configurations. However, many of the transition elements have electron configurations that are not predicted by the rules for determining electron configuration.
The abbreviated electron configuration of sodium is [Ne]3s1.
Group 18
any time there are as many electrons and protons and they fill each orbital optimally.
The externall shell of electrons is completely filled.
The element argon (atomic number 18) has the electron configuration 1s22s22p63s23p6 which can be abbreviated [Ne] 3s23p6
The electron configuration of boron is [He]2s2.2p1.
