I have a gr12 chemistry assignment on the newly discovered elements (Uut, Uup, Uus and Uuo) and I have to talk about why they don't agree with the periodic law, but I can't find anything about it online.Anyone here know about why?

[AWK]

If these are elements they should agree with periodic law, otherways this is not law. Exclusions rather mean that we do not know exact properties of these elements since only a few very unstable atoms of them were obtained.

[OTI]

Here's a hint. Those elements were man-made.

[Borek]

Here's a hint. Those elements were man-made.

And? Periodic law is universal and doesn't say anything about source of an element.

[discodermolide]

As these are man-made I don't think there is enough of them to confirm their properties. Their properties may be inferred from their position in the element groups, however, this does not mean that they will necessarily have these properties. There will probably never be enough to confirm or deny similarity to their partners.

[Enthalpy]

Could the question just refer to transition elements?

Here's a hint. Those elements were man-made.

... as were the Laws determining the periodic table, mostly from human-observable data derived from material behaviour in the narrow range of states encountered on the surface of this planet.

Chances are that the measurements were wrong, given the extremely short time available.

Nice to see actual experimentation happening again.
