Question: Okay so i have a few. What element: 1. is yellow, found in matches and our body, has distinctive odour when it burns and used to be called BRIMSTONE? 2.used to make "mag" wheels and flash cubes? 3. is poisonous that used to be found in house paint and automobile gasoline? 4. is radioactive that used to be used to make watch hands visible in the dark. Named after the term to "radiate" light. Thanks soo much for the help :) Please help! i need these answers BEFORE tomorrow. I have no idea what those answers are, i need them for my homework.

I don't know #2 but as for the rest, Sulfur (S) is yellow and found in our body and in matches and has a very distinctive odour. Lead (Pb) is a heavy metal element that is poisonous so they took it out of paint and gasoline... which is too bad because the reason it was in paint in the first place is that it made really vibrant colours. Radium (Ra) used to be painted on watch-hands to make them visible in the dark... the people who did the painting licked the tips of their brushes and ingested this element. How unfortunate.

Step 1 - Gather Information The first thing you will need to do is find some information about your element. Go to the Periodic Table of Elements and click on your element. If it makes things easier, you can select your element from an alphabetical listing. Use the Table of Elements to find your element's atomic number and atomic weight. The atomic number is the number located in the upper left corner and the atomic weight is the number located on the bottom, as in this example for krypton: Step 2 - The Number of Protons is... The atomic number is the number of protons in an atom of an element. In our example, krypton's atomic number is 36. This tells us that an atom of krypton has 36 protons in its nucleus. The interesting thing here is that every atom of krypton contains 36 protons. If an atom doesn't have 36 protons, it can't be an atom of krypton. Adding or removing protons from the nucleus of an atom creates a different element. For example, removing one proton from an atom of krypton creates an atom of bromine. Step 3 - The Number of Electrons is... By definition, atoms have no overall electrical charge. That means that there must be a balance between the positively charged protons and the negatively charged electrons. Atoms must have equal numbers of protons and electrons. In our example, an atom of krypton must contain 36 electrons since it contains 36 protons. Electrons are arranged around atoms in a special way. If you need to know how the electrons are arranged around an atom, take a look at the 'How do I read an electron configuration table?' page. An atom can gain or lose electrons, becoming what is known as an ion. An ion is nothing more than an electrically charged atom. Adding or removing electrons from an atom does not change which element it is, just its net charge. For example, removing an electron from an atom of krypton forms a krypton ion, which is usually written as Kr+. The plus sign means that this is a positively charged ion. It is positively charged because a negatively charged electron was removed from the atom. The 35 remaining electrons were outnumbered by the 36 positively charged protons, resulting in a charge of +1. Step 4 - The Number of Neutrons is... The atomic weight is basically a measurement of the total number of particles in an atom's nucleus. In reality, it isn't that clean cut. The atomic weight is actually a weighted average of all of the naturally occurring isotopes of an element relative to the mass of carbon-12. Didn't understand that? Doesn't matter. All you really need to find is something called the mass number. Unfortunately, the mass number isn't listed on the Table of Elements. Happily, to find the mass number, all you need to do is round the atomic weight to the nearest whole number. In our example, krypton's mass number is 84 since its atomic weight, 83.80, rounds up to 84. The mass number is a count of the number of particles in an atom's nucleus. Remember that the nucleus is made up of protons and neutrons. So, if we want, we can write: Mass Number = (Number of Protons) + (Number of Neutrons) For krypton, this equation becomes: 84 = (Number of Protons) + (Number of Neutrons) If we only knew how many protons krypton has, we could figure out how many neutrons it has. Wait a minute... We do know how many protons krypton has! We did that back in Step 2! The atomic number (36) is the number of protons in krypton. Putting this into the equation, we get: 84 = 36 + (Number of Neutrons) What number added to 36 makes 84? Hopefully, you said 48. That is the number of neutrons in an atom of krypton. The interesting thing here is that adding or removing neutrons from an atom does not create a different element. Rather, it creates a heavier or lighter version of that element. These different versions are called isotopes and most elements are actually a mixture of different isotopes. If you could grab atoms of krypton and count the number of neutrons each one had, you would find that most would have 48, others would have 47, some would have 50, some others would have 46, a few would have 44 and a very few would have 42. You would count different numbers of neutrons because krypton is a mixture of six isotopes. In Summary... For any element: Number of Protons = Atomic Number Number of Electrons = Number of Protons = Atomic Number Number of Neutrons = Mass Number - Atomic Number For krypton: Number of Protons = Atomic Number = 36 Number of Electrons = Number of Protons = Atomic Number = 36 Number of Neutrons = Mass Number - Atomic Number = 84 - 36 = 48

There are always the same amount of electrons as protons, so the atom is always neutral, if it were not it would no longer be an atom but an ion. Sulfur_____S______atomic mass 32 ___ atomic number 16 ______ protons 16____ neutrons 16____ electrons 16 Hope this helps :-)

Fluorine is by far the most interesting element. 1. the most electronegative 2. the second smallest after H 3. the most reactive non-metal Fluorine is highly important in organic chemistry, pharmaceuticals, medicine, and drugs. The carbon fluorine is one of the strongest bonds between carbon and any other atom. In medicine, Fluorine's radioactive isotope F-18 is used to do PET Scans which doctors used to trace drugs administered into patients to come out with a diagnosis or find out what areas of the human body are drugs affecting. For example, if you are treating a cancer patient with an anti-cancer drug you can tag the drug with an F-18 isotope and then trace it (like a GPS system follows your car) to see if the drug is going where it is supposed to go and doing its job. A lot of drugs made from pharmaceuticals contain either contain a F atom, a CF3 group, or a several F atoms placed specifically in certain locations. The reason for this is because the drugs are more effective. They get to where they need to get much faster. When you take a pill, the acids in your stomach dissolve the pill and then the drug gets into your blood but before it does this it needs to pass through the layers of fat and this becomes the hardest part of all. So by adding F atoms you make the drug a bit more slippery and it gets to where it needs to get to much faster. It's like a newspaper boy delivering newspapers to their homes. If he uses a bicycle it takes a long time but if he uses a car or a much faster method of transportation then his job will be much easier.

i like carbon. diamonds are cool. graphite is cool. both have carbon, in a similar way, yet one is really tough and the other not so.
