:: Physics is dead. These so-called elements exist for a fraction of a second. No chemical-molecules are possible; no weighable amount ::
First, I must point you to “mass v. weight”. You get what that means, I’m sure.
YET...and that’s a BIG YET!
I agree with you, sir (ma’am?). So-called “Chemical-Physicists” are creating short-life “elements” for their own professional purpose and advancement. We should always determine the STABLE life of any thing we want to add to the Table.
Otherwise it is, simply put, designer chemistry.
Perhaps, but they are successfully filling out the periodic table, which is organized by atomic number.
These elements aren't stable, but we didn't know that until someone created them, and observed them to decay quickly.
Perhaps they will find an element with a higher atomic number that IS stable, and has a useful property.
