BerylliumBeryllium heeft maar één stabiel isotoop 9 Be. Onder invloed van de kosmische straling waaraan onze atmosfeer blootstaat wordt een kleine hoeveelheid van het radioactieve isotoop 10 Be gevormd. Dit proces is vergelijkbaar met de vorming van 14 C, maar 10 Be heeft een veel langere kan daarom gebruikt worden om geologische processen zoals erosie en vorming van aardlagen te volgen.
Beryllium: Chemical reactions | Pilgaard ElementsBeryllium is passivated by oxygen, forming a BeO surface which is resistant to acid. On a fresh surface, without the protective layer, beryllium dissolves readily in dilute acids such as sulphuric acid, H 2 SO 4, hydrochloric acid, HCl, and nitric acid, HNO 3, forming Be(II) ions and hydrogen gas, H 2. Ba (s) + 2 H + (aq) Ba 2+ (aq) + H 2 (g)
Chemical Physical Properties of BerylliumBeryllium, basic physical and chemical properties of the element
Which element have the most similar chemical properties? · The elements in the first column of the Periodic Table (other than hydrogen) are known as Group 1A metals, or alkali metals. When you compare the chemical properties of these elements (lithium, sodium, potassium, rubidium, cesium, and francium), what you'll notice is that they are all remarkably similar.
BerylliumBeryllium is light, silvergray, relatively soft metal that is strong but brittle. Beryllium has the highest melting point of the light metals, melting at 1278 o C – considerably higher than, for example, Lithium (180 o C) Sodium (98 o C) Magnesium (650 o C) Aluminum (660 o C) or Calcium (839 o C).
BERYLLIUM CHLORIDE | CAMEO Chemicals | NOAAAcidic salts, such as BERYLLIUM CHLORIDE, are generally soluble in water. The resulting solutions contain moderate concentrations of hydrogen ions and have pH's of less than They react as acids to neutralize bases. These neutralizations generate heat, but less or far less than is generated by neutralization of inorganic acids, inorganic ...
Chemistry for Kids: ElementsBeryllium is a very rare metal that is almost never found in its pure form. It is part of the alkaline earth metals group which makeup the second column of the period table. Characteristics and Properties In its free state beryllium is a strong, but brittle metal.
