can anyone explain valency of silver with step by step please
Answers
Answer:
atomic number=number of protons=number of electrons.
All atoms trying to attain nearest Noble gas's outer shells electronic configuration.(almost 2&8 electrons).In other words try's to fill outer shell electrons like noble gases outer shell's electronic configuration
electronic configuration follows in shells as.
ex:-k,l,m and n
k=2, l=8, m=18 and n=32 (formula=2n^2, n=electron shell place)electrons.
silver=Ag
atomic number=47
the electrons in silver distribute in shells as follows.
k=2
l=8
m=18
and n=19
hear we can see that the last shell has 19 electrons,
so it give 1 electron to attain 18electron.
it is easy to give 1 electron for silver to fill last shell like noble gas
Answer:
Silver is a group 11 transition metal in the 5th period of Periodic table with symbol Ag (Argentum from Latin word). The atomic number is 47 and the mass number of the silver is 107.86.It is soft white lustrous metal.It is good conductor of heat and electricity. It is less resistive metal that is the main reason why it exhibits good conductivity among all the metals in the periodic table, Metal is mainly found in pure elemental form or an alloy with gold and other metals. The main ores of silver are argentite and chlorargyrite.
Valency of an element refers to the combining capacity of an element with other to form compound. Silver forms the electronic configuration as [Kr] 4d^10 5s^1. and electrons per shell is 2, 8, 18, 18, 1. 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. But in some exceptional cases it exhibit valency as 2, when it loses electrons from the stable d sub-shell to exhibit transition property of metals.
