Beryllium

About this type of question: My answer is that beryllium is small in size. So, the charge density (charge/radius) is extremely high. So, the force of attraction between the electrons in orbitals and proton in nucleus is very strong. When beryllium is encountered with the other elements (i.e. chlorine), the electrons cannot loss to environment(due to strong force of attraction), but the beryllium will be polarised to become positively charge and hence attract the electron from other elements to form the covalent compound (BeCl2 which is Cl-Be-Cl). So the beryllium hydride is a polar covalently bonded compound.

There are four electrons in a Beryllium atom. Hence the mono positive ion has only three electrons. Therefore the electron configuration is 1s2 2s1.

Beryllium chloride is acidic in water because it undergoes hydrolysis, where water molecules react with the beryllium ions to form beryllium hydroxide and hydrochloric acid. The resulting hydrochloric acid contributes to the acidic nature of the solution.

It is difficult to estimate precisely how much beryllium is left on Earth as new sources could be discovered. However, known beryllium reserves are abundant and could last for many years at current consumption rates. Recycling of beryllium-containing products also helps to sustain its availability.

Beryllium is not normally present in the blood of healthy individuals. Occupational exposure to beryllium can result in the metal entering the bloodstream, leading to systemic toxicity. Blood tests can be used to measure beryllium levels in individuals who may have been exposed to it in the workplace.

The outer shell number for beryllium is 2. Beryllium has 4 electrons, so in its electron configuration, 2 electrons are in the first energy level and 2 electrons are in the second energy level, making the outer shell number 2.

No, beryllium is actually a very good conductor of heat and electricity. Its high thermal conductivity and low electrical resistance make it useful for applications in industries like aerospace and electronics.

The name for Be(NO2)2 is Beryllium Nitrate(III) or Beryllium Nitrite

The specific heat of beryllium is approximately 1.825 J/g°C. This value represents the amount of energy required to raise the temperature of 1 gram of beryllium by 1 degree Celsius.

The most common cross section of Beryllium is a hexagonal close-packed (HCP) structure. This arrangement allows Beryllium atoms to be closely packed together, maximizing their interactions and stability.

Beryllium and phosphorus can form an intermetallic compound called beryllium phosphide (Be3P2).

Beryllium's reactivity is primarily due to its ability to lose two electrons to form a +2 ion, which creates a more stable electron configuration. This reactivity makes beryllium readily combine with other elements to form compounds. Additionally, beryllium has a small atomic radius and high effective nuclear charge, contributing to its reactivity.

Beryllium is used in nuclear reactors as a neutron reflector or moderator. It helps to slow down neutrons to increase the probability of their interaction with the nuclear fuel, promoting the chain reaction. Beryllium's ability to effectively reflect and moderate neutrons makes it a valuable material for enhancing the efficiency of nuclear reactors.

Scandium is a natural chemical element, a solid metal.

Some applications are:

- component of some lasers

- the oxide is used in high intensity lamps

- the iodide is used in halogen lamps

- etc.

Beryllium sulfate is a white crystalline solid compound that is used in the manufacturing of ceramics, inorganic pigments, and as a catalyst in organic reactions. Due to its toxicity, it is regulated and controlled in industrial processes to protect workers and the environment.

Fredrich Wohler did not discover beryllium, but rather the element beryllium was discovered by French chemist Louis-Nicholas Vauquelin in 1798. Wohler is best known for his synthesis of urea from ammonium cyanate in 1828.

There are a total of 16 subatomic particles in 2 beryllium atoms. Each beryllium atom contains 4 protons and 4 neutrons in its nucleus, as well as 4 electrons orbiting the nucleus.

i dont know sorry No. It is characterized by stiffness.

Chemical reactions of the elements Reaction of beryllium with air: Beryllium is a silvery white metal. The surface of beryllium metal is covered with a thin layer of oxide that helps protect the metal from attack by air. It does not oxidize in air even at 600°C. However, powdered beryllium metal does burn in air to give a mixture of white beryllium oxide, BeO, and beryllium nitride, Be3N2. Beryllium oxide is more normally made by heating beryllium carbonate. 2Be(s) + O2(g) → 2BeO(s) 3Be(s) + N2(g) → Be3N2(s) Reaction of beryllium with water: Beryllium metal does not react with water or steam, even if the metal is heated to red heat. Reaction of beryllium with the halogens: Beryllium metal reacts chlorine, Cl2, or bromine, Br2, to form the beryllium dihalides beryllium (II) chloride, BeCl2, and beryllium (II) bromide, BeBr2, respectively. Be(s) + Cl2(g) → BeCl2(s) Be(s) + Br2(g) → BeBr2(s) Reaction of beryllium with acids: The surface of beryllium metal is covered with a thin layer of oxide that helps protect the metal from attack by acids, but powdered beryllium metal dissolves readily in dilute acids such as sulphuric acid, H2SO4, hydrochloric acid, HCl, or nitric acid, HNO3, to form solutions containing the aquated Be(II) ion together with hydrogen gas, H2. Be(s) + H2SO4(aq) → Be2+(aq) + SO42-(aq) + H2(g) Reaction of beryllium with bases: Beryllium metal dissolves readily in dilute aquesous base solutions such as sodium hydroxide, NaOH, to form Be(II) complexes together with hydrogen gas, H2. Magnesium (immediately below beryllium in the periodic table) does not do this.

Yes, beryllium dichloride (BeCl2) is a nonpolar molecule. It has a linear molecular geometry due to the arrangement of atoms around the central beryllium atom, resulting in symmetrical distribution of charge and no permanent dipole moment.

Magnesium, calcium, strontium, barium and radium have similar properties to beryllium.

All the elements in group two of the periodic table have the same or similar properties. This is because they have the same number of electrons in their outermost shell.

By blowing Lithium, duh. Seriously though, I'm guessing you mean why is beryllium such a prominent material in modern technology, not why it has atomic number 4 on the periodic table... which is because it has 4 protons in its nucleus. The answer to this is due to beryllium's extraordinary physical properties. Its very low density, along with a melting point of 1278 C and an ability to remain stable at high temperatures while resisting thermal expansion make beryllium ideal for use in alloys, especially in the fields of aeronautics and particle physics, where its capability for withstanding many types of radiation is of vital importance.

Beryllium is a neutron-reflective metallic substance that has been used in the making of nuclear weapons. As a veteran of the US Navy, I cannot confirm nor deny the presence of nuclear weapons on this, or any other naval ship or station...

Since I was not in the "nuke" department (many navy vessels have nuclear propulsion) I'm not sure if it is used in the construction of reactors.

Usually, any attempt by a group or an individual to acquire beryllium will result in attracting the attention of the local intelligence agency...

The symbol for beryllium is Be, and the symbol for chloride is Cl. Therefore, the symbol for beryllium chloride would be BeCl2.
