Beryllium
Beryllium is a chemical element with the atomic number 4 and the symbol Be. The main source of Beryllium is the stars, though it is relatively shortlived when synthesized. It is a relatively rare element in the universe as well as on Earth.

Why electron affinity of beryllium is zero?
Asked by Wiki User
Electronic configuration of beryllium: 1s2.2s2.
What is the room temperature of berylium?
Asked by Wiki User
The room temperature of anything is the temperature of the room it is in. Beryllium has the following important temperature points. Melting point --- 1560° Kelvin - 1278° Celsius - 2349° Fahrenheit Boiling point --- 2742° Kelvin - 2469° Celsius - 4476° Fahrenheit
What is the standard atomic notation of beryllium?
Asked by Wiki User
Beryllium is a solid metal at room temperature.
How do beryllium carbon and oxygen produce star?
Asked by Wiki User
As helium builds up in the sun's core, other fusion reactions occur. Over time, two or more helium nuclei can fuse, forming beryllium. Another helium nucleus can fuse with a beryllium nucleus, forming carbon, and so on. Stars the size of the sun do not contain enough energy to produce elements heavier than oxygen. But larger stars do.
The Sun isn't making those elements; what of them exist are the result of production in other stars. Currently, the Sun makes only helium, which, although it's really a gas, was named "sun metal."
Edit: The Sun will make heavier elements later, but only up to oxygen. The way stars like the Sun make carbon and oxygen is by nuclear fusion. This is the same way they make helium from hydrogen. This process of making elements is called nucleosynthesis. The details can get quite technical, but the basic idea is
that one atomic nucleus combines with another to produce the nucleus of a new element.
What is the chemical formula for beryllium nitrade?
Asked by Wiki User
There is no such thing as "nitrade."
The formula for beryllium nitrate is Be(NO3)2; the formula for beryllium nitride is Be3N2.
How did beryllium get where it is now?
Asked by Wiki User
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.
Is beryllium nitride a molecular or ionic?
Asked by Wiki User
Covalent. Be is highly electronegative to form ionic bonds.
Why does beryllium have four electrons?
Asked by Wiki User
In the excited state of Beryllium the electron configuration is Be = 1s2 2s1 2p1 this is caused by one electron from 2s orbital jumping to 2p orbital to create a new orbital to allow maximum bond capacity. Maximum bond capacity is mostly used in hybridization in organic chemistry. The two new orbitals that have 1 electrons need to get a pair so each can pair with 1 electron thus making Beryllium bond with 2 electrons.
What streak does beryllium have?

What is the texture for beryllium?
Asked by Wiki User
the color of the mineral beryl can change, depending on the sample
Does beryllium have a isotope?
Asked by Wiki User
Beryllium has 4 protons and electrons and a variable number of neutrons, depending on the isotope. For other atomic properties see the links bellow.
Why is beryllium important to the earth?
Asked by Wiki User
The abundance of beryllium in the earth crust is 2-3 ppm.
What is the size of the atom?
Asked by Wiki User
It does depend a fair amount on the poo particles. The smallest atom is a hydrogen atom (37 picometers) whereas some larger atoms more than 5 times larger (lanthanum is 187 picometers). If the atom is an ion, it will also change it's radius significantly (positive ions are smaller and negative ions are larger than the neutral atom).
What is the word equation for beryllium carbonate?
Asked by Wiki User
beryllium is Be
carbonate is CO3-2
Where is beryllium used in a cell phone?

The Beryllium stands out with a huge 3.2 inch crystal clear LCD touch screen and is housed inside a strong, beautiful metal case for everyday use. The simple and elegant interface is easy to use and provides you with the tools and options you need for any occasion. Aside from the standard call functions, the Beryllium offers an abundance of call handling features and PDA software tools to let you stay on top of your work and social life.The Beryllium also offers a full assortment of Bluetooth functions so you can hook it up with your Bluetooth head phone for wireless conversations or music. You can even pair it with your Car DVD System for a safer and easier time while driving.
Is beryllium natural or man-made?
Asked by Wiki User
Scandium is a natural chemical element, a solid metal.
Some applications are:
- alloying component for aluminium
- material for X-ray tubes (anticathode) used in X-ray spectrometry
- component of some lasers
- the oxide is used in high intensity lamps
- the iodide is used in halogen lamps
- etc.
