  Kazimierz Fajans Summary
Afterwards Fajans was working on the electrochemical properties of elements as a result of the radioactive changes, and he formulated the law of the radioactive moves which was later named the Soddy-Fajans Method (Frederick Soddy received the Nobel Prize in chemistry in 1921 for his isotopic research).
Fajans and Otto Hahn were the discoverers of the formula that defined the conditions of the precipitation and absorption of radioactive substances.
The co-relation of Born, Fajans and Haber is one of the basic termochemical rule.

  Kazimierz Fajans - Wikipedia, the free encyclopedia
Kazimierz Fajans (sometimes referred to as Kasimir or Casimir; 27 May 1887 - 18 May 1975), was a Polish-American chemist who did valuable work on chemical bonding and on radioactivity and isotopes.
He was born in Warsaw and educated at Leipzig, Heidelberg, Zurich and Manchester.
In inorganic chemistry, he formulated what became known as Fajans rules to account for the formation of covalent rather than ionic bonds.

 AllRefer.com - Fajans, Kasimir Information
In inorganic chemistry, Fajans formulated two rules to account for the diagonal similarities between elements in the periodic table in terms of the ease of formation of covalencies and electrovalencies (ionic valencies).
The first rule states that covalencies are more likely to be formed as the number of electrons to be removed or donated increases, so that highly charged ions are rare or impossible.
Fajans was born in Warsaw and educated at Leipzig, Heidelberg, Zürich, and Manchester.

Rules of law: You need to label the rules of law prominently, so that you can extract them easily, to paraphrase them into if/then form, fuse them with related rules, organize them, and make your outline or other topical review materials of the chapter.
Most of the time, the rules will be stated in the reasoning, sometimes in several reiterations, as the court quotes or paraphrases various supporting authorities.
Dissenting opinions urge the opposite judgment and holding, and both often use reasoning and rules of law that differ from those in the majority opinion.

An extension of the electrochemical considerations with reference to the emanations has indicated that between radium, ThX and ActX on the one hand, and the three emanations on the other, the existence of alkali elements is to be assumed, for which the provisory designations RaX, ThX
However, such an assumption is in contradiction to the rule of the alteration of groups in the transformations, for then there would be in the transformation Ra --

 Fajans' rules@Everything2.com
Formulated by the Polish-born chemist Kasimir Fajans in 1923-4, these rules govern the degree of covalency present in ionic compounds.
Fajans' rules state that there is a tendency towards increasing covalency when:
Therefore the bonding in beryllium oxide (BeO) has a strong covalent character in addition to the ionic bonding, because the ions have a double charge and beryllium ions are also very small.

 Isotopes: Soddy
About 10 years later, he unravelled the rules for the elemental transformations which accompanied radioactive decay, first for α decay and later for β decay.
These rules taken together are known as the Displacement Law; Kasimir Fajans published it slightly earlier than did Soddy [Fajans 1913, Soddy 1913a].
[12] With the sequence of changes fully elucidated and the chemical character of the majority of the radio-elements established, the α-ray rule was shown to hold generally, and, equally generally, a similar rule for the β-ray changes was found to apply.

 AllRefer.com - Fajans's rules Information
In chemistry, guidelines for estimating if a compound is likely to form ionic bonds as opposed to covalent bonds.
The rules state that ionic bonds are more probable if (a) the ionic charge is low, (b) the size of the anion is small, (c) the size of the cation is large, and (d) if the cation has the electronic configuration of a noble (rare) gas.
The rules were proposed by Polish-born US chemist Kasimir Fajans.

The method is simply to assign a color to the important components of a case: red for legal facts, rulings and conclusions; green for the facts; blue for the issues; and fl for the law.
For example, if you are using a case for its precise statement of the rule which you later want to capture for your notes, then highlighting is an efficient way for you to quickly see the relevant text that you want to incorporate into your study outline.
Often, it is only after having read several cases on a topic that you will have fleshed out the rule of law on a particular point, including its elements, definitions of the elements, exceptions to the rule, and any counter-rules.

 Pearson's Hard Soft [Lewis] Acid Base
These empirical (experimentally derived) rules tell us that Type A metals are more likely to form oxides, carbonates, nitrides and fluorides, while Type B metals are more likely to form phosphides, sulfides and selinides.
Ionic-covalent character in metal plus non-metal binary materials can be calculated using the Pauling equation, here, but the difference in electronegativity underestimates the effect of polarisation: the extent to which one atom distorts or polarises the electron cloud of the other.
Fajans rules clearly explain this chemistry by saying that the very small, highly charged Be ion is able to polarise the two chloride ions into a molecular covalent structure.
