Is there a property of an element that is not periodic? If any?

Are you asking "Is there a property of an element that does not arise from its position in the periodic table?"

Yep, that guy told me that the 'physical state' is one such property.

OK. I'll give it some thought. I haven't thought of anything yet.

If by 'physical state' he meant whether it is solid, liquid, gas, and plasma, then I disagree. These are not properties of the element since an element can have its state changed but still be the same element.

Got a couple.

Isotopes are not shown in the periodic table. An element may give off 'particles' eg. be radioactive. You cannot tell by looking at the table.

Carbon may exist in many forms: diamond, graphite etc. So for example how hard it is, is a property that is not governed by its position in the table, but rather by how the atoms are bonded to each other.

Can you really call the allotropies of carbon a property of an element

Charles Janet thought Helium should be above Beryllium!

but he was a biologist.

The color ( flame test ) of an element is a property. It can not be determined by the periodic chart.

The spectral lines of an element can not be determined by its position in the periodic chart.

You may be right, but as these lines depend on electron jumps, there may be a link. Maybe it's just that no one has found it yet.

That could be your PhD thesis, Agnishom.

Thank you for the idea. But what if there isn't a link?

Then you investigate what does cause it.

Or in that case, I'll show how it isn't linked
