iron has a valency of 2 in some compounds, such as ferrous sulphate (FeSO4), and a valency of 3 in others, such as ferric chloride (FeCl3). There are two sorts of valencies in copper: 1 and 2. Mercury
An elementAhas4electrons in the outermost shell of its atom and combines with another elementBhaving7electrons in the outermost shell of its atom. The compound formed does not conduct electricity. What is the nature of the chemical bond in the compound ? Give the electron-dot structure of its...
Why the elements are arranged in a table? The chemical elements are arranged inorder of increasing atomic number. ... This is because they have the same number of outer electrons and the same valency. An example of a group in the periodic table is the alkali metal group. ...
