What is the Valency of AG?
Silver is a group 11 transition metal in the 5th period of Periodic table with symbol Ag (Argentum from Latin word). In most case the valency of Ag is 1, as the d sub-shell has stable configuration if they loss 1 electrons from s sub-shell. There fore the most common valency of silver is 1.

- Chemical reactions. The number of electrons in an atom's outermost valence shell governs its bonding behavior. Therefore, elements whose atoms can have the same number of valence electrons are grouped together in the periodic table of the elements.
- Uranium is a chemical element with symbol U and atomic number 92. It is a silvery-white metal in the actinide series of the periodic table. A uranium atom has 92 protons and 92 electrons, of which 6 are valence electrons. Many contemporary uses of uranium exploit its unique nuclear properties.
- This means that neutral zinc atom has a total of 30 electrons surrounding its nucleus. To see how many of these electrons are valence electrons, write the electron configuration of a neutral zinc atom. Notice that the outermost shell, which for zinc is the fourth shell, n=4 , has two electrons.
Structure of the Silver Atom. The silver atom has 5 electron orbits (energy levels) with a total of 47 electrons. Beginning with the orbit closest to the nucleus and working outward, the number of electrons per orbit should be: 2, 8, 18, 18, 1.
- 4 valence electrons
- About 16 radioactive isotopes of silver are known also. A radioactive isotope is one that breaks apart and gives off some form of radiation. Radioactive isotopes are produced when very small particles are fired at atoms. None of the radioactive isotopes of silver has any commercial use.
- The others were gold, copper, lead and iron. Silver objects dating from before 4000 BC have been found in Greece and from slightly later in Anatolia (in modern Turkey). Silver artifacts have been found in the Sumerian city of Kish dating from about 3000 BC.
The silver atom has 5 electron orbits (energy levels) with a total of 47 electrons. Beginning with the orbit closest to the nucleus and working outward, the number of electrons per orbit should be: 2, 8, 18, 18, 1. Of course, the nucleus contains 47 protons and 61 neutrons.
- Interesting question ….Gold (Au) atomic number 79 has an electronic structure 2, 8, 18, 32, 1. So straight away from this fact, you would say it has 1 valence electron, its outer single electron. And indeed, it forms many univalent compounds such as the gold halides (AuF, AuCl, AuBr).
- 4 valence electrons
- Iodine has 53 protons and 53 electrons (because it has no charge the number of protons equals the number of electrons). Iodine-131 has 131 protons and neutrons. Iodine-131 has 131 minus 53 protons = 78 neutrons.
