How do you make an atom model of Boron?
- a normal sized ball of styrofoam and about 16 little styrofoam balls.
- 2 styrofoam rings
- paint (orange, green, red, blue, yellow)
- toothpicks
paint the normal sized ball and paint it orange. Then paint the rings green. connect on ring and the normal sized ball together. paint 5 small sty. balls red, 6 blue, 5 yellow. then connect the red balls and blue balls with toothpicks and put them on the orange ball. then on the ring that's connected to the ball, put 2 yellow balls on it .
now connect then 2nd ring to the ring that's connected to the ball and place the rest of the yellow balls on the 2nd ring. Remeber connect everything with toothpicks.
How many valence electrons are in boron?
3 valence electrons
There are three valance electrons. These are the electrons in the outer shell if it is not full.
What country was boron discovered in?
Boron was known a thousand years ago and it's abundant in Tibet. due to caravans and trades it finally came to Arabia and called it Boraq (Borak) or Borax.
Sooooo........ what's the answer???
What are some uses of ammonium citrate?
Ammonium Citrate in distilled water is an alternate developer for Platinum and Palladium photographic prints (Iron replacement by Pt and/or Pd). It is cooler in resulting print color than the usual developer - Potassium Oxalate. See www.bostick-sullivan.com
Crystalline Boron costs approximately $5,000
Amorphous Boron costs approximately $2,000
Amorphous Boron can be used for pyrotechnic flares (which makes it turn a bright green color) and it can ignite rockets.

Boron is in the p-block and is located in period 2 of the periodic table.

Compounds of boron have been around since ancient times, Egyptian mummification could not have been accomplished without it. Boron is not a naturally free element. The element was not isolated until 1808 and it was not identified as the element boron until 1824. See the related link for more information on this subject.
What does the element boron smell like?
Boron itself does not have a distinctive smell. However, compounds containing boron can have various odors depending on their specific chemical structure.
Boron has been used in China since 300AD. But it was discovered as an element in 1824 by Jöns Jakob Berzelius
What is the importance of boron?
Boron is a chemical that is naturally occurring in Earth's crust and outer space. Boron in very small quantities is important for maintaining levels of calcium, magnesium, phosphorous in the body.
Boron itself is a black or dark brown solid. However, in compounds, boron can exhibit a range of colors, depending on its oxidation state and the other elements it is bonded with.
What is the oxidation state of boron?
The oxidation state of boron is either three electrons or one electron. Boron has an valence electron configuration of ns2np1.
Boron can be dangerous if ingested in large quantities. It can cause upset stomach, vomiting, and diarrhea. Long-term exposure to high levels of boron can be harmful to the reproductive system.
Boron itself is odorless. It is a solid metalloid that does not emit any discernible smell.
What is the valence electron configuration for boron?
Boron exists in period 2, group 13 (IIIA) of the periodic table, with valence of 3 electrons in the outer shell. The electron configuration of boron is 1s22s22p1
What are some characteristics of the boron group?
The boron family, Group 13 on the periodic table, is sort of a collection of "odd ducks" in that boron is a metaloid and aluminum, gallium, indium and thallium are poor metals. All of these elements have 3 electrons in their outer electron or valence shell. The (poor) metals find a lot of use, particularly aluminum. Boron is useful in the chemical industry for inclusion in various materials.
No, boron is not a halogen. Boron is a metalloid element, while halogens refer to a group of elements in the periodic table that include fluorine, chlorine, bromine, iodine, and astatine.
With what family does boron belong?
Boron belongs to the family of elements known as metalloids or semimetals.
Where is boron found in nature?
Boron is found in nature in compounds such as borax, boric acid, and various minerals. It is commonly found in the Earth's crust and oceans, as well as in soil, rocks, and plants. Boron is also present in some volcanic spring waters and hot springs.
Is boron magnetic or non magnetic?
Boron is the chemical element that's listed as B on the periodic table. It's classified as a metalloid, and is not magnetic in the least.
Jons Jakob Berzelius discovered and classified boron as an element in 1824. It was first isolated by Sir Humphry Davy, Joseph Louis Gay-Lussac and Louis Jacques Thénard in 1808. The first pure boron was produced by the American chemist W. Weintraub in 1909, although as usual, this is disputed by some researchers.
