They are called methanides because Be or Al on decomposition in water gives Methane(CH4).
Beryllium fluoride.
BeS is an ionic compound called beryllium sulfide. It is composed of beryllium (Be) cations and sulfide (S) anions. Beryllium has a +2 charge, while sulfide has a -2 charge, leading to a neutral compound.
Beryllium comes from Greek beryllos, beryl. It has also been called Glucinium or Glucinum from the Greek word glykys which means "sweet."
The name for Be(OH)2 is beryllium hydroxide.
Sodium beryllium oxide (Na2BeO2) is a compound composed of sodium (Na), beryllium (Be), and oxygen (O) atoms. It is also known as sodium beryllate. This compound is a white crystalline solid that is used in the production of beryllium metal and various beryllium compounds.
Aluminium is called "एल्यूमिनियम" (aluminium) in Hindi.
Beryllium and phosphorus can form an intermetallic compound called beryllium phosphide (Be3P2).
Beryllium is a member of group 2, an Alkaline Earth Metal.
The chemical formula for beryllium chlorite is Be(ClO2)2.
Beryllium fluoride.
Tungsten carbides are generally called as carbides. Cobalt with Tungsten carbide acts as a binder. When Cobalt added with other elements like Ni / Cr / Mo / Ti are called as cemented carbides. Sintering is a thermal treatment given to these carbides so as to eleminate the porosities and densify them. During this treatment cobalt binds the WC particles and we get high density.
BeS is an ionic compound called beryllium sulfide. It is composed of beryllium (Be) cations and sulfide (S) anions. Beryllium has a +2 charge, while sulfide has a -2 charge, leading to a neutral compound.
Aluminium is a metal (an element), not an alloy. This means that it's only made up of aluminium atoms. It has no other impurities in it. Aluminium ore is called bauxite. This has aluminium plus other substances in it, but aluminium on its own is a metal with just aluminium atoms in it.
Beryllium (Be) is a metal. It is in group 2 on the periodic table, which are called the alkaline earth metals.
Beryllium comes from Greek beryllos, beryl. It has also been called Glucinium or Glucinum from the Greek word glykys which means "sweet."
Like many other fighter aircraft of that period, Spitfires were made from an aluminium frame and skinned with an aluminium alloy called 'dural'.
Aluminium is called ''Energy Bank'' because the energy saved in recycling.
