Arrange the following elements in the order of their decreasing metallic character: Na, Si, Cl, Mg, Al:

Cl > Si >Al > Mg > Na Na >Mg >Al >Si > Cl Na > Al > Mg > Cl > Si Al > Na> Si > Ca > Mg

Newlands’ law of octaves for the classification of elements had the following limitations. Choose the correct limitation:

Newlands assumed that only 56 elements existed in nature and no more elements would be discovered in the future. Newlands’ law of octaves was applicable to the classification of elements up to calcium only. In order to fit elements into his table, Newlands put even two unlike elements having very different properties. All the above.
