Beryllium

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.

Beryllium oxide: electric insulator but thermal conductor, ceramics for high temperatures, nuclear applications as neutrons reflector, etc. Beryllium fluoride was used in the Molten Salt Reactor Experiment.

The atomic number of Beryllium is 4.

Yes, beryllium is a lustrous metal. It has a shiny surface when freshly cut, but can develop a dull patina over time due to oxidation.

Beryllium was discovered in France by the French chemist Louis-Nicolas Vauquelin in 1798.

The chemical formula for beryllium perbromate is Be(BrO4)2.

Beryllium oxyde (BeO) is a chemical compound, not a metal or a nonmetal.

I think lithium should be more reactive as it has only 1 valance electron wheres Boron has 3 valance electrons. The electro positivity(tendency to lose electrons) of Lithium is greater then Boron, therefore more reactive.

The chemical formula for beryllium arsenide is Be3As2. It is composed of 3 beryllium atoms and 2 arsenic atoms.

The short answer is because Be(OH)2 reacts with strong acids, like H2SO4, to produce Be(SO4) and 2H2O. On the other hand, Be is very different than the other members Mg, Ca, Sr, and Ba in that it forms covalent bonds. This is evident from the much lower boiling and melting point of its salts compared to the other group 2 elements. In water Be(+2) exists as [Be(H2O)4](+2). In the presence of strong alkali this species undergoes reaction to give [Be(H2O)2(OH(-1)2] displacing two moles of water. This species is insoluble and precipitates. The addition of further strong alkali gives [Be(OH(-1))4](-2)] which is water soluble. Aluminum behaves similarly.

One should deal with any beryllium compounds "theoretically" never experimentally unless the lab is especially equipped to handle beryllium. It is not only carcinogenic, its compounds are chemically extremely acutely toxic

Beryllium forms an amphoteric oxide because it has the ability to exhibit both acidic and basic properties. In the case of beryllium oxide (BeO), it can react with both acids and bases to form salts. This property is due to the ability of beryllium to accept or donate protons in chemical reactions.

Beryllium is in column 2 of a wide form periodic table and column II(A) of a narrow form periodic table.

Zero.

It has 4 electrons and thus it's electron configuration is 1s2 2s2. Each s orbital can only hold 2 electrons and since each has 2, there are are no unpaired electrons.

roses are red violets are blue beryllium is my love how about you?

The element that is differentiated from beryllium lithium nitrogen nickel and tin is oxygen. Oxygen is a chemical element with symbol O and atomic number 8. It is a member of the chalcogen group on the periodic table a highly reactive nonmetal and an oxidizing agent that readily forms oxides with most elements as well as with other compounds. Oxygen is the most abundant element by mass in the Earth's crust as part of oxide compounds such as silicon dioxide and the most abundant element in the Earth's atmosphere.

Oxygen has several properties that differentiate it from beryllium lithium nitrogen nickel and tin including:

• Atomic number 8
• Atomic weight 15.9994
• Group Chalcogens
• Period 2
• Block p

Additionally oxygen has a variety of oxidation states from -2 to +6 and is a colorless odorless tasteless gas. It is the third most abundant element in the universe and is essential to all known forms of life.

Beryllium and iodine are both chemical elements found on the periodic table. They have unique properties and are used in various industrial applications. Both elements have specific uses in different industries, with beryllium being used in aerospace and electronics, while iodine is used in medicine and photography.

The chemical formula for beryllium hydroxide is Be(OH)2.

About 11 amu. 6 protons and 6 electrons in the elemental forms. One's an alkaline earth metal that easily ionizes and forms compounds with other species, the other's a noble gas. Shall I go on?

To make beryllium copper alloy, beryllium is melted into copper, usually with a copper beryllium master alloy that contains a controlled amount of beryllium. The mixture is then cast into the desired shape and cooled to solidify, resulting in the beryllium copper alloy.
