Concept explainers
Interpretation:
The correct statements from the given set of statements should be given.
Concept introduction:
The
The same electronic configuration containing elements are arranged in the same group in periodic table. The vertical columns of the periodic table are known as families. The elements present in the column are said to be of the same family.
The
While naming a covalent compound, the first element is named first followed by the naming of the second element. If the first element exhibits more than one oxidation state then the current oxidation state being exhibited is to be mentioned.
