Question:I am doing an assignment that asks for a bohr model of boron.. however, it is an ION of boron, not a regular atom, so I must deal with valence electrons etc. I know that boron has three valence electrons but I want to know how many should be in the other energy levels, since the ion will have 8 electrons not 5, like a usual atom of boron.
Many thanks to whoever answers!!
Answers:The regular boron atom has 2 electrons in the first shell and 3 in the next (outer/valence shell). Boron is a nonmetal, so it will always add electrons to become an ion. It will add 5 electrons in the valence shell, so the boron ion has 2 in the inner shell and 8 in the outer shell.
Question:In science class we have to build three 3D atomic structure models: Boron, Magnesium, and Argon. All i need now is to know their uses, and how their atomic structure helps. GRACIAS
Answers:Argon is used for welding as a shield gas, this is because it is inert. it prevents immediate corrosion of the weld.
Question:Okay so my mother is clueless with my explanation on how to make a boron atom model in to a cake she gives me a dumb founded look. I was tying also to explain to her that the "nucleus" in the cake needs to be raised and once again i get a dumb founded look. So can you give me a good explanation on how it should look
Answers:So you need to make an edible cake for a class about an atomic model? Well the easiest thing i can think of is either make a round cake and draw with icing the protons (represented as +), the neutrons (represented as 0), the electrons ( represented as -), and the electron cloud (represented as twizler stretched around the cake twice to make the 2 clouds. Use colorful icing. I hope this is what youre talking about. lol if not, i just designed a pretty odd looking cake.
Question:i'm making a 3D model of an atom (boron) for my science project. it needs to hang from the ceiling so it needs to be a mobile. i don't want to use wire to make the rings because they are too flimsy. do you have any ideas of what materials i could use? i want to use Styrofoam balls for the electrons...do you think that would work?
Answers:You could use steel spring wire, it is much stronger than copper wire or regular steel wire. You could also use ping-pong balls over Styrofoam because they are hollow and are much lighter than even Styrofoam.
What Is Boron :What Is Boron Name Origin From borax and carbon. "Boron" in different languages. Sources Obtained from kernite, a kind of borax (Na2B4O7.10H2O). The world wide commercial borate deposits are estimated to be 1010 kg of boron. The USA, Tibet, Chile and Turkey are important producers. Around 1 million tons of boric anhydride (B2O3) are produced each year. Abundance Universe: 0.001 ppm (by weight) Sun: 0.002 ppm (by weight) Carbonaceous meteorite: 1.6 ppm Earth's Crust: 950 ppm Seawater: 4.41 ppm Human: 700 ppb by weight 410 ppb by atoms Uses Used with titanium and tungsten to make light weight heat resistant alloys. Also tennis rackets, regulators in nuclear plants, heat resistant glass and eye disinfectant. Boric acid (H3BO3) is used an insectiside, mostly against ants or cockroaches. Boron nitride is a material in which the extra electron of nitrogen (with respect to carbon) enables it to form structures that are isoelectronic with carbon allotropes. Sodium tetraborate decahydrate (Na2B4O7 - 10H2O) or borax, used in the production of adhesives, in anti-corrosion systems and many other uses. Sodium tetraborate pentahydrate (Na2B4O7 - 5H2O), which is used in large amounts in making insulating fiberglass and sodium perborate bleach. Orthoboric acid (H3BO3) or boric acid is used in the production of textile fiberglass, flat panel displays and eye drops. Boron slurry is used as an energetic material with very high energy density like rocket fuels and jet engines.
