Ground-state electron configuration of silver (Ag):<\/strong> Explanation<\/strong><\/p>\n\n\n\n Silver (Ag) has an atomic number of 47. This means it has 47 electrons in its neutral ground state. To write the electron configuration, we start from hydrogen and fill orbitals in the order prescribed by the Aufbau principle, which prioritizes lower-energy orbitals first. The general order of filling is:<\/p>\n\n\n\n 1s \u2192 2s \u2192 2p \u2192 3s \u2192 3p \u2192 4s \u2192 3d \u2192 4p \u2192 5s \u2192 4d \u2192 5p, and so on.<\/p>\n\n\n\n Following this order, you would expect the electron configuration of silver to be:<\/p>\n\n\n\n [Kr]\u20094d9\u20095s2[Kr]\\, 4d^9\\, 5s^2[Kr]4d95s2<\/strong><\/p>\n\n\n\n However, the actual configuration is:<\/p>\n\n\n\n [Kr]\u20094d10\u20095s1[Kr]\\, 4d^{10}\\, 5s^1[Kr]4d105s1<\/strong><\/p>\n\n\n\n This occurs due to a phenomenon related to electron stability. A fully filled or half-filled subshell offers extra stability due to symmetrical distribution and exchange energy. In the case of silver, moving one electron from the 5s orbital to complete the 4d orbital gives a full 4d^10 configuration, which is more stable than the expected 4d^9 5s^2 arrangement.<\/p>\n\n\n\n This irregularity is similar to what we see in other elements such as copper (Cu), which has an electron configuration of [Ar] 3d^10 4s^1 instead of the expected [Ar] 3d^9 4s^2. In both cases, a filled d-subshell offers a lower energy state overall.<\/p>\n\n\n\n Using the noble gas shorthand, we begin with [Kr], the electron configuration for krypton, which accounts for the first 36 electrons. The remaining 11 electrons fill the orbitals as 4d^10 and 5s^1. This results in the most stable and experimentally observed ground-state configuration for silver.<\/p>\n\n\n\n Understanding such exceptions is important for explaining physical and chemical properties such as atomic size, ionization energy, and bonding behavior.<\/p>\n\n\n\n Write the complete ground-state electron configuration of Ag.
