Why halides of berilium fume in moist air but other alkali metals do not?
Beryllium halides fume in moist air because they form hydrolysis products, such as beryllium hydroxide, which are volatile and can be observed as fumes. Alkali metals do not fume in moist air because their halides are typically more stable and less prone to hydrolysis.
Why beryllium can be easily hydrolysed?
Beryllium doesn't react with water at room temperature.
What does ran polymerase do?
Polymerise dna fragments
How many different elements make up beryllium sulfite?
The elements in beryllium sulfite can be easily determined by looking at the formula. They are beryllium (Be), sulfur (S), and oxygen (O).
Is beryllium flammable or combustable?
Beryllium is in fireworks. Beryllium is used in fireworks to change the color of the effect to a white color.

Why do halides of Be polymerise?
Beryllium is covalent and polymeric. Each beryllium atom is bonded to four hydrogen atoms and each hydrogen atoms forms two bonds as it is bridiging two Be atoms. Since Be has two valence electrons and H only one, it is apparent that there are not enough electrons to form the usual electron pair bonds in which two electrons are shared between two atoms. Instead of this , three-center bonds are formed in which a 'banana-shaped' molecular orbital covers three atoms BE...H...Be, anc contains two electrons.The monomeric molecule BeH2, if formed with normal bonds, would have only four electrons in the outer shell of the beryllium atom and would be electron deficient. This would make the molecule very unstable; that is why BeH2 exists as polymer.
How many different elements make up beryllium sulfite BeSO3?
The elements in beryllium sulfite can be easily determined by looking at the formula. They are beryllium (Be), sulfur (S), and oxygen (O).
Is beryllium a lightweight metal through which X-rays pass easily?
Yes, beryllium is transparent to x-rays; windows of x-rays tubes are made from a thin foil of beryllium.
Why vinyl halides and arylic halides are less reactive than other halides?
In vinyl and arylic halides, Carbon Halogen bond have double bond character due to presence of lone pair of electron on halogen atom. So it can not be easily broken as compared to carbon halogen bond in other halides, so they are more reactive than other halides.
What does ran polymerase do?
Polymerise dna fragments
Halides 7 valence electrons?
Halides with 7 valence electrons typically have a -1 charge, such as chlorine (Cl-) and bromine (Br-). These elements can easily gain one electron to form a stable octet configuration.
How many different elements make up beryllium sulfite?
The elements in beryllium sulfite can be easily determined by looking at the formula. They are beryllium (Be), sulfur (S), and oxygen (O).
What does halides have in it?
well halides have usually other atoms in it but these halides have fluorine chlorine and calcium
What are the properties and reactivity of pseudo halides in comparison to traditional halides?
Pseudo halides have similar properties and reactivity to traditional halides, but they are not true halides. They can act as halogens in chemical reactions, but they may have different characteristics due to their structure. Overall, pseudo halides exhibit some similarities and differences compared to traditional halides.
