848 Questions

What color does boron when burned?

Green and is used with fireworks.

What is the formula for boron carbonate?

The chemical formula for boron carbonate is B4C3O12.

What is the economic value of boron?

In August 2010 it was £3.06 per lb

Is boron difluoride ionic or covalent?

Boron difluoride is a covalent compound. It is formed by sharing electrons between boron and fluorine atoms, rather than transferring them to form ions.

What is boron the element's atomic weight?

The atomic weight of boron is approximately 10.81 atomic mass units.

Who is the element boron named after?

Boron was not named after an individual. The mineral borax was know to ancient peoples, though they could not know its chemistry. Borax was called buraq in Arabic. From Middle-Persian, we get būrak, which is the root for burah in Persian. The name boron comes from these words for borax, and boron is one of the elements that makes up this mineral. A link can be found below for more information.

Boron is and example of what?

Boron is an example of a chemical element. It is a metalloid with atomic number 5 and is commonly found in compounds such as borax and boric acid. Boron is used in various industries, including glass manufacturing and agriculture.

What is the color of boron at room temperature?

Boron is typically black or brown in its elemental form at room temperature.

How do you build a boron Molecule Model?

First of all, Boron is an element, so it would need to be bonded to other elements to form a molecule. As for making the molecule, the good ol' stick'n'ball method never (almost) fails. Use styrofoam balls as the atoms of various elements (use different sizes to reflect the varying atomic radii), and use toothpicks or straws to represent the bonds (e.g. one toothpick for a single bond, two for a triple bond, etc.). Thi is probably the simplest way to go about it, and if used to its full potential, can display a surprising amount of information.

What is the crystal structure of boron?

Boron has a unique crystal structure called rhombohedral boron, which consists of B12 icosahedra linked together in a three-dimensional network without a regular repeating pattern.

Does boron conduct electricity?

Boron is a semiconductor and does not conduct electricity as well as metals do because its electron structure has gaps in its energy band that prevent easy movement of electrons. However, boron can conduct electricity under certain conditions, such as at high temperatures or when doped with other elements.

What is the forumula for boron trifluoride?

The formula for boron trifluoride is BF3. It consists of one boron atom bonded to three fluorine atoms.

How do boron 10 and boron 11 differ?

For starters they are both isotopes of Boron. The boron in the periodic table has an atomic weight of 10.8, which is basically the average of all of boron's isotopes' atomic weights.

An isotope is an atom of an element with the same number of protons, but a different numberof neutrons.

This means that the atomic number (proton number: in boron's case this is 5) is the same (which is good, as it's the number of protons which determines what element is which), but the mass number will be different.

For example. Carbon 12 has 6 protons, 6 neutronsand 6 electrons. A well known isotope of Carbon 12 is Carbon 14. Note that the number is always the mass number. This means that in Carbon 14, there are still 6 protons and 6 electrons (we know this as it is still carbon; hence still has 6 protons, and is still neutral; hence still has 6 electrons), but there are 8 neutrons.

So the difference between boron 10 and boron 11 is that boron 10 has one less neutron than boron 11, or, equally, boron 11 has one more neutron than boron 10.

This means that they will have the same chemical properties (will react the same), but will have different physical properties (eg. Boron 11 will be slightly heavier than boron 10).

Is there an interesting fact about the element boron?

Yes! Boron is the only non-metallic element in Group 13 of the periodic table and is essential for the growth of plants. It's also used in various industrial applications, such as in the production of fiberglass and borosilicate glass.

Boron wood preservative?

With one minor problem, boron is an exceptional wood preservative. It will kill any insect. It' is completely non-toxic to humans, and it even makes wood fire-retardant. The minor problem is that it leaches out of the wood when the wood gets wet. Boron is used in four processes. First is SillBor--a pressure treatment for sill plates in walls, intended to keep bugs from eating the sill plates. Second is fire retardant treatment, which is done by at least Columbia Wood Products--a big manufacturer of hardwood plywood. Third is the treatment they apply to wood-frame windows, and finally there is Copper Boron Azole pressure-treatment. The azole group locks the boron into the wood.

What is the compound formula for boron hydride?

Boron hydrides. The boron hydrides are called boranes with general formula Bn Hn+4 and Bn Hn+6. The well known boron hydrides are: diborane (B2H6), tetraborane (B4H10), pentaborane (B5H9), hexaborane (B6H10), nonaborane (B9H15), and decaborane (B10H16). The boron does not combine with hydrogen to form boron hydrides. They catch fire spontaneously air. All the borones react with ammonia, but in the products depend on the condition :

Borone nitride
Borazole

Is Boron non reactive or reactive?

Boron is typically considered to be reactive, although it is less reactive compared to elements like sodium or chlorine. Boron can form compounds with other elements through bonding, such as in borax or boric acid.

The atomic number of boron is 5 what does this tell you about an atom of boron?

The atomic number of boron (5) indicates the number of protons in the nucleus of a boron atom. This means that a boron atom has 5 protons. Since atoms are electrically neutral, it also tells us that a boron atom has 5 electrons to balance the positive charge of the protons.

Is there boron in milk?

Yes, milk contains trace amounts of boron, which is an essential micronutrient for human health. However, the concentration of boron in milk is relatively low compared to other foods like fruits, nuts, and vegetables.

What are the uses of boron steel?

It's steel that Boron owns.

For example: The steel that Fred has, called Fred steel.

What are the uses for boron?

Boron has a large nuclear cross section, which means that it interacts with neutrons easily. (Specifically, the isotope 10B) As such, it can be used to control reactivity in a nuclear reactor. Often, the control rods contain boron. One of the last ditch emergency reactivity control systems is based on sodium pentaborate, which is liquid boron that can be injected into a runaway core. Also, boric acid is injected into the core of pressurized water reactors (PWR's) during refueling to adjust reactivity against the new fuel.

Besides nuclear uses, boron is used in bleach, fiberglass, glass and ceramic to aid in resistance to thermal shock, and organic synthesis. It can also be used in the medical treatment of tumors in boron neutron capture therapy.

What is the luster of boron?

Boron does not have a distinct luster as it is typically found in an amorphous powder form. It is a non-metal and does not display metallic luster like other metals.

How many atomic number of boron?

There is only one atomic number for any element. For boron, it is 5.

6.201023 atoms of boron contains how many grams of boron?

This cannot be possible. Atoms cannot be divided or separated, meaning there cannot be a part of an atom. Either you have 6 atoms or 7 atoms, etc. You can't however, have 6.5 atoms or 9.63 atoms. When expressing a number of atoms that has a decimal, usually it will be due to scientific notation, which requires it.
