Silver has one valence electron.
Silver has one valence electron.
one electron in the 5s orbital
Silver's electron configuration is 2, 8, 18, 18, 1.
There are 18 valence electrons represented in the Lewis electron-dot structure for SO2.

In the calculation of valence electron counts using the 18-electron rule, phosphine (PH3) contributes 5 valence electrons. Since each hydrogen atom contributes 1 electron, the total valence electron count for PPh3 (Ph = phenyl group) would be 5 (from phosphorus) + 3x1 (from hydrogen) = 8 electrons.
A chloride ion has 18 electrons, giving it a valence of -1.
Materials used for conductors generally contain 1 to 3 valence electrons, such as copper, silver, and gold. These valence electrons are free to move and contribute to the material's conductivity.
Valence electrons are the outer layer of electrons, the part that reacts. Argon is a noble gas, so it has a full valence electron level. It has eight valence electrons.
To find the number of valence electrons for an atom, you need to look at its electron configuration. The valence electrons are the electrons in the outermost energy level of an atom. You can determine the number of valence electrons by looking at the electron configuration or the periodic table. For main group elements (Groups 1, 2, 13-18), the number of valence electrons is given by the group number. For example, group 1 elements have 1 valence electron, group 2 have 2 valence electrons, and so on.
Silver is a metal. Metals usually can take on many charges and lose "free" electrons from orbitals other than the outer one. However, silver is unusual in that it only takes a +1 charge indicating it has 1 free electron on its valence shell.
