What is Thallium? What is Lutetium? What is Ytterbium? What is Erbium? Discussion Comments Byanon31373— On May 04, 2009 what are the uses of promethium? what are the physical properties of promethium? All The Science, in your inbox ...
What is the atomic number of thallium? Atomic Number: Atoms are made up of protons, neutrons, and electrons. The protons and neutrons are found in the nucleus of the atom, while the electrons are outside the nucleus. The atomic number is the number of protons, while the mass number is ...
What are the purposes of quenching? What is the Warburg effect? What is DPPF ? What would be more apt to produce crystalline: (a) HDPE (b) poly(butyl methacrylate) What is alkalinity? What are the formal charges in O_3? What are some properties of a candle?
energy is released. This affinity is known as the first electron affinity, and these energies are negative. By convention, the negative sign shows a release of energy. However, more energy is required to add an electron to a negative ion which overwhelm...
What to Tell the Veterinarian or a Pet Poison Hotline When a pet has been or is suspected to be poisoned, time is of the essence. Delays in treatment can cause damage to their organs and possibly have fatal results. Contact your veterinarian as soon as you are aware or suspect poisoning...
Shapes and properties of glass pH membranes. Types of Reference Electrodes The reference electrode/system and the hydrogen ISE (i.e. the electrode with the glass membrane) can be separate electrodes or they can be combined into a single electrode for convenience. The combination-style electrode is...
What are the ideal properties of scintillation materials? The perfect scintillator should bedense, bright and fast. Dense means high density and high atomic number ≳ 5 g/cm3, which increases the probability of a gamma-ray interaction. The denser the scintillator, the more efficient it is at...
1. PtCl2 (platinous chloride) properties: green-brown hexagonal powder crystal with a density of 6.05g/cm3. It decomposes when heated. It is insoluble in water, ethanol and ether, and is slightly soluble in dilute hydrochloric acid. Generates H2[PtCl4] (platinochloric acid). Preparation metho...
Properties of X-rays They are: • Propagated in straight lines at the speed of light • Absorbed while passing through matter, depending on composition and density of the substance • Emitted with energies characteristic of the elements present They: • Cause biological reactions such as ...
Medical professionals may also prescribe Prussian blue for use in treating people who have been internally exposed to cesium or thallium. Internal exposure can happen through ingestion or inhalation, and it can be quite dangerous when not quickly treated. The pigment binds to these elements, preventi...
