The World's Greatest Books — Volume 15 — Science From the molecular orbital diagram of N2, predict its bond order and whether it is diamagnetic or paramagnetic. Chemistry 2019-02-14T00:00:00Z Which of these two directions is taken by the axis depends on whether the crystal is paramagnetic or diamagnetic, and on whether the principal axis is the direction of maximum or minimum magnetization. Encyclopaedia Britannica, 11th Edition, Volume 7, Slice 7 "Crocoite" to "Cuba" 2012-01-22T03:00:24.397Z He anchored one end of it there by flipping the paramagnetic control on the tape case, and pulled the tape across the room. Breaking Point The first group is paramagnetic and positive; the corresponding one is diamagnetic and negative. Occult Chemistry Clairvoyant Observations on the Chemical Elements It becomes less paramagnetic, volume for volume, as it is rarefied, and apparently in the simple proportion of its rarefaction, the temperature remaining the same. The World's Greatest Books — Volume 15 — Science Can a molecule with an even number of electrons ever be paramagnetic? Chemistry 2019-02-14T00:00:00Z He regarded the first class of substances as attracted, and the second class as repelled, and called them respectively paramagnetic and diamagnetic substances. Beacon Lights of History, Volume 14 The New Era; A Supplementary Volume, by Recent Writers, as Set Forth in the Preface and Table of Contents The former he called paramagnetic and the latter diamagnetic bodies. The Story of Electricity III.—Boron, scandium and yttrium were examined; they are all triatomic, paramagnetic, and positive. Occult Chemistry Clairvoyant Observations on the Chemical Elements He afterwards employed the term magnetic to cover the whole phenomena of attraction and repulsion, and used the word paramagnetic to designate such magnetic action as is exhibited by iron. Faraday as a Discoverer Explain why is diamagnetic, while which has the same number of valence electrons, is paramagnetic. Chemistry 2019-02-14T00:00:00Z They point out that the apparent repulsion of diamagnetic substances is due to the fact that they are less paramagnetic than the oxygen of the air in which they are suspended. Beacon Lights of History, Volume 14 The New Era; A Supplementary Volume, by Recent Writers, as Set Forth in the Preface and Table of Contents Remember that molecules such as O2 that contain unpaired electrons are paramagnetic. Chemistry 2019-02-14T00:00:00Z The corresponding group consists of nitrogen, vanadium and niobium; they are triatomic, paramagnetic, and negative. Occult Chemistry Clairvoyant Observations on the Chemical Elements They are all monads and paramagnetic; lithium, potassium and rubidium are positive, while fluorine and manganese are negative. Occult Chemistry Clairvoyant Observations on the Chemical Elements Materials with unpaired electrons are paramagnetic and attracted to a magnetic field, while those with all-paired electrons are diamagnetic and repelled by a magnetic field. Chemistry 2019-02-14T00:00:00Z During this investigation Faraday observed some phenomena that led him to a belief in the existence of another form of force, distinct from either paramagnetic or diamagnetic force, which he called the magne-crystallic force.
