Link to the lesson.

Extremely important aspects of the boron neutron capture therapy are, first of all, administering to the patient a boron compound that selectively reaches the neoplastic cells, and in the second step, the verification of the irradiation process. This paper focuses on the latter aspect, which is the detailed dosimetry of the processes occurring after the reaction of thermal neutrons with the boron isotope. The results of computer Pełny tekst do pobrania w serwisie zewnętrznym. The microscope analysis showed the presence of iron-rich nanocrystals formed on the Bi-Fe-V-O grains. The X-ray diffraction studies confirmed that grains are built mostly of tetragonal Bi4V1. Electrical properties of beryllium-alumino-tellurite glasses and glass—ceramics doped with iron ions were studied using impedance spectroscopy.

The first thing to notice here is that this compound contains a metal, sodium, and a nonmetal, oxygen, so right from the start, you know that you're dealing with an ionic compound. Now, sodium is located in group 1 of the Periodic Table , which means that an atom of sodium has 1 valence electron. Oxygen, on the other hand, is located in group 16 of the Periodic Table, which means that an atom of oxygen has 6 valence electrons. In order to name this compound, use the name of the cation first and the name of the anion last. Stefan V. Mar 24, Sodium oxide. Explanation: The first thing to notice here is that this compound contains a metal, sodium, and a nonmetal, oxygen, so right from the start, you know that you're dealing with an ionic compound.

It is the anhydride form of sodium hydroxide. When sodium burns in the air it burns with a bright, white light. When it burns in oxygen it burns even more brightly. It forms a white powder called sodium oxide. Sodium oxide molecules are made up of two sodium cations and one oxygen anion. Thus, Na 2 O molecules feature two sodium-oxygen ionic bonds.

Zbadano mieszane przewodnictwo polaronowo-jonowe w kilku rodzinach szkieł tlenkowych zawierających tlenki metali przejściowych. Prześniak-Welenc P. Barczyński T. Task 5. Tymińska M. The ac and dc conductivity in phosphate-iron-niobate glasses with addition of titanium oxide was investigated as a function of temperature and frequency with the use of impedance spectroscopy. Szczególną uwagę zwrócono na typowe zmiany przewodnictwa występujące przy domieszkowaniu tego typu szkieł jonami metali alkalicznych. Gryzińaki J. The percentage composition, i. The applied doping affects the T c value by The decrease in conductivity was more pronounced for larger alkali ions.

Ionic compounds do not exist as molecules. In the solid state, ionic compounds are in crystal lattice containing many ions each of the cation and anion. This formula merely indicates that sodium chloride is made of an equal number of sodium and chloride ions.
