Elements In Groups

The radioactive form of an element acts in the same way the nonradioactive form does. When a person ingests iodine it concentrates in the thyroid gland whether it is in a radioactive or nonradioactive

The Copper (II) Nitrate had the most impressive reactions of all the substances in my mind.. The substance turned yellowish-green and dissolved immediately when introduced to HCl. When it was heated directly over the flame it melted and started producing gas in the test tube. When mixed with cold water it dissolved into a clear blue liquid, but then behaved very violently when boiled with water.

and Cl - . If Ag + was present instead, then the solution would have consisted of silver chloride

An elements¡¦ reaction to certain substances may be predicted by its placement on the Periodic Table of Elements. Across a period, an element on the left will react with more vigor than one on the right, of the same period. Vertically, as elements are sectioned into groups, the reaction of each element increases

The radical chlorination of chlorobutane is performed using AIBN and sulfuryl chloride. The purpose in doing this is so that the 4 different products yielded could be observed and analyzed. The four products produced are, 1,1-dichlorobutane, 1,2-dichlorobutane, 1,3-dichlorobutane, and 1,4-dichlorobutane. For each product the chlorine adds in a different location relative to the original chlorine. This is due to a number of reasons, including the degree of carbon substitution and proximity to the chloro substituent.. The goal with this in the experiment was to find out why each product is given in different yields. Experimentally, to determine the effect of the chloro substituent on the reactivity per hydrogen, a gas

Introduction: The purpose of this lab was to find the relative solubilities of some salts of the Alkaline Earths and use that information to find the order which they appear in the periodic table; also use that information to efficiently find an unknown alkaline earth halide. Also to find the relative oxidizing powers of the Halogens given and using that information finding the order of the Halogens in the periodic table; also use that information to efficiently find an unknown Halogen.

Does the little known element bromine affect the globe so much to the point that without it, human life would cease to exist? The answer could be surprising. bromine is a natural, liquid at room temperature element that belongs to the group Halogen, which includes similar elements such as chlorine, iodine, and astatine. It is an extremely poisonous element that could cause long-term kidney and brain issues from its systematic poisoning effect; the element bromine is a reddish-brown color and exceedingly fetid. Though it was originated from a college student’s work, a French scientist wrote an article about bromine before the student could pursue it. No matter how it was discovered, scientists are grateful for it.

A few metal elements in high temperatures may enter an excited state and they’re seen by emitting a light of color. Comparing the substance flame with the flames of the reference table will help identify the element of the unknown metal. First we placed each of the liquefied metals in flames and observing their color changes by collecting data. Lastly, observing the color of the liquefied metal, placing it in the flame with a wire loop could emit a color change and this concludes the experiment. The unknown metal was exactly the metal ion that was hypothesized. The unknown metal

Astatine, where do we start? How about its atomic number? Astatine is number 85 on the periodic table. All the way down in period six and it is a halogen. It is five foot seven feet tall and a little bit on the chunky but funky side. Oh wait! That is me not Astatine. Astatine is actually really, really rare. To be exact, only 0.05 micrograms of it has been produced. How was it

Iodine 131 emits Beta and Gamma radiation. Beta radiation consists of electrons and its penetrating power is very low whereas Gamma

Iodine consumption immediately increases the detoxification of bromide, fluoride, and some heavy metals including mercury, lead, cadmium, and aluminum. Bromide and fluoride are only removed by iodine, and no other chelator or detoxifying technique. Many people know that toxic halides, such as fluoride and bromide, have an effect on the receptors in the body similar to iodine, and can inhibit iodine absorption and binding in the body. Even though iodine is part of the halides family, which are all opposing elements to iodine, they will obstruct the absorption of iodine. We are all exposed to bromine and fluorine, your bodies are storing these toxic chemicals in the receptors meant for iodine. The human body’s receptors are primitive and lacking

Iodine is a member of the halogens group meaning it has seven valence electrons. Valence electrons are electrons in the outermost shell of an electron orbital. The reason why all of the halogens on the periodic table have a valence of seven is due to their electron configuration, specifically in the S and P orbitals. Iodine has an electron configuration of 1s2 2s2 2p6 3s2 3p6 3d10 4s2 4p6 4d10 5s2 5p5, the noble gas configuration is [Kr] 4d10 5s2 5p5. This results in iodine having the quantum numbers of n= 5 due to it being in the fifth energy level, and a sub-shell number of L= 1 due to the last electron of iodine being found in the p orbital. Iodine also has a very high electron affinity that relates to its electron configuration. Since

The reaction is initiated very easily much the same way as hydrogen and oxygen. Valence Chlorine usually forms compounds with a valence of -1 but it can combine with a valence of +1, +2, +3, +4, +5, or +7. 2.1.2. Chemical Reactions Reactions with Water Chlorine is only slightly soluble in water (0.3% to 0.7%) depending on the water temperature.

Balard found bromine chemicals in the ash of seaweed. The seaweed was used to produce iodine, but also contained bromine. Balard distilled the bromine from a solution of seaweed ash saturated with chlorine. The properties of the left over substance resembled that of an intermediate of chlorine and iodine, he was sure that he had found a new element and named it muride, derived from the Latin word muria for brine.
