My teacher is allergic to chlorine. Would he also have a bad reaction to fluorine, bromine and other elements of that group?
Since elements of the same group have similar properties, right? I'm taking chemistry for fun and trying not to overwhelm my instructor with too many silly questions.
EDIT: My teacher may have meant sensitivity and not allergy. English isn't his first language.

Nanobots Coated with a layer of fluorine
Iβm writing a paper for school about nanobots and a new application of the technology. My idea is that I coat these nanobots with fluorine or a similar chemical that has a high affinity for calcium. I canβt find any other chemicals or compounds that have a high affinity for calcium or calcium oxalate. I also understand that fluorine gas is toxic but what about fluorine in a solid state?

In "Ignition", John Clark cites that James Dewar falsely stated liquid fluorine to have a density of 1.108, when the real value is 1.5. Is there more information on this error?
Does anyone know where the number originally was published by Dewar? Or anywhere in the literature where people used that number and had bad results? The book says it went 60 years unquestioned - how did that end? Who corrected the value? What caused them to correct it? What methods would have been used at the time to find the density, and why would Dewar get it wrong and someone else get it right?

It seems Bob Lazar DID state the isotope of 115.
There are a few people who have queried why Bob Lazar knows the atomic number of the spacecraft "fuel" (number of protons - 115), but never mentions the mass number (protons + neutrons). This information would be useful because the theory of an island of stability is predicated on getting the number of protons and neutrons correct - thus far, all isotopes of 115 produced are unstable.
Well, there is a diary of Joe Vaninetti (one of Bob's close friends circa 1989) online. This diary notes down information Bob appears to have offered over 8 or so months. This diary states that the atomic weight of 115 is 271.
This would put the number of neutrons at 156. This is basically as far away from the theorized magic neutron numbers of 126 and 184 as you could get. If a 115 sample is to be stable, it is assumed that the neutron shells will be closed at a neutron number of 184. Of course, humans may be way off with our theories on the island of stability...

Why doesnβt anybody want to find more stable isotopes of existing elements?
With all the talk about discovering new elements, other elements are just left behind. Take astatine, for example. While it theoretically has a stable isotope, itβs still heavier than any isotope discovered or created. Itβll surely be easier to add more neutrons to astatine than try to make element 119 or 120. With the many, possibly unique properties of the those near the end of the periodic table, it seems like a no-brainer to try and look into those as well as discovering new ones.
