The most common and stable valency of Silver (Symbol: Ag) is +1. Although silver is a transition metal—a group of elements famous for exhibiting variable valencies like iron or copper—silver is relatively unique in that it almost exclusively shows a +1 oxidation state in its chemical compounds under normal conditions.
Symbol: Ag (Argentum)
Atomic Number: 47
Electron Configuration: [Kr] 4d¹⁰ 5s¹
Most Common Valency: +1
Ion Formed: Ag⁺
Rare Valency: +2 (in compounds like AgF₂)
Silver has an atomic number of 47. You might expect its electron configuration to be [Kr] 4d⁹ 5s², following standard orbital filling rules. However, completely filled d-orbitals (d¹⁰) offer exceptional stability. Because of this, one electron from the 5s orbital jumps to the 4d orbital.
Therefore, the actual electron configuration of Silver is [Kr] 4d¹⁰ 5s¹.
Looking at its electron configuration ([Kr] 4d¹⁰ 5s¹), silver has exactly one electron in its outermost shell (the 5s orbital), and a completely full, highly stable 4d subshell.
When silver reacts, it easily loses that single 5s electron to form the Ag⁺ ion. Once that electron is gone, the remaining electron structure has completely full shells and subshells, which is chemically very stable. Because it takes a massive amount of energy to remove a second electron from the stable 4d¹⁰ core, silver rarely exhibits valencies higher than +1.
Technically, yes, but it is extremely rare. Under highly specific, harsh oxidative synthetic conditions, silver can be forced to exhibit a valency of +2 (e.g., in Silver(II) fluoride, AgF₂). However, these compounds are highly reactive, unstable, and act as incredibly strong oxidizing agents because they desperately want to gain an electron to return to the stable +1 state. For general chemistry purposes and standard curriculum, the valency of silver is considered to be 1.
Because of its +1 valency, silver forms compounds such as:
The most common and stable valency of silver is +1.
Silver's electron configuration is [Kr] 4d¹⁰ 5s¹. It has a single electron in its outermost 5s shell, while its 4d shell is completely full and stable. It readily loses this one 5s electron to form the stable Ag⁺ ion.
Yes, but it is very rare. In highly oxidative conditions, silver can form compounds like AgF2 where it shows a valency of +2, but these are highly unstable.
Silver Nitrate (AgNO₃) is a common compound where silver exhibits a valency of +1.
