Why do the elements chlorine and iodine have similar chemical properties?
139959
They are both members of the halogen group, which is the column they are in on the periodic table.  All elements in a group have similar chemical properties, as their outer electrons are the same.  Halogens all have 7 electrons, so they need 1 to have a complete shell.  Therefore, they usually like to take an electron from another atom and carry a -1 charge.\n\nHowever, as you move down a group, the atoms get progressively larger.  Therefore, iodide is larger than chloride.

Here is the answer.. Just remember periodi table...\nElements on left most side are electro positive and elements on right most are electro negative. (The last row is nobel gases..so leave it)\nNow Cl- belongs to right most side... its more electro-ve\nRb, Ca are on left side.... they are electro positive(They will give  electron with out much force)\nSi, S are in middle-- their properties are in between...\n\nThats it!

Bromine (from Gr. βρωμος (brómos), meaning "stench"; pronounced [ˈbɹomin]), is a chemical element in the periodic table that has the symbol Br and atomic number 35. A halogen element, bromine is a red volatile liquid at standard room temperature which has a reactivity between chlorine and iodine. This element is corrosive to human tissue in a liquid state and its vapors irritate eyes and throat. Bromine vapors are very toxic upon inhalation.\n\nNotable characteristics\nBromine is the only liquid nonmetallic element at room temperature and one of only two liquid elements on the periodic table (the other is mercury). The pure chemical element has the physical form of a diatomic molecule, Br2. It is a heavy, mobile, reddish-brown liquid, that evaporates easily at standard temperature and pressures in a red vapor (its color resembles nitrogen dioxide) that has a strong disagreeable odor resembling that of chlorine. A halogen, bromine resembles chlorine chemically but is less active. It is more active than iodine, however. Bromine is slightly soluble in water, and highly soluble in carbon disulfide, aliphatic alcohols (such as methanol), and acetic acid. It bonds easily with many elements and has a strong bleaching action.\n\nBromine is highly reactive and is a powerful oxidizing agent in the presence of water. It reacts vigorously with amines, alkenes and phenols as well as aliphatic and aromatic hydrocarbons, ketones and acids (these are brominated by either addition or substitution reactions). With many of the metals and elements, anhydrous bromine is less reactive than wet bromine; however, dry bromine reacts vigorously with aluminium, titanium, mercury as well as alkaline earth metals and alkaline metals.

As mg said, yes indeed, all Halogens' are diatomic along with H, N, O, and even Ar (a Noble Gas!). \n\nA note, however, Astatine is so rare it is usually not considered to be a diatomic. \n\n. . . and a little known fact . . . some metals are diatomic in their gaseous state.\n\nGet an "A".

Chlorine is a highly reactive element, and undergoes reaction with a wide variety of other elements and compounds.\n\nChlorine is a good bleaching agent, due to its oxidising properties.\n\nChlorine is soluble in water (which solution is called Chlorine Water) and this loses its yellow colour on standing in sunlight, due to the formation of a mixture of Hypochlorous Acid and Hydrochloric Acid.\n\nCl2 + H2O ==> HOCl + Hcl \nWhen Chlorine Water (i.e. a solution of chlorine gas in water) in a flask inverted in a basin of the same liquid is exposed to bright sunlight, the Chlorine is decomposed and a solution of Hydrochloric Acid remains.\nH2O + Cl2 ==> HCl + HClO\nThe Hydrochloric Acid, HClO, is not very stable and the solution readily decomcomposes, especially when exposed to sunlight, yielding Oxygen.\n2 HClO ==> 2 HCl + O2 \n\nhope this helps u to find out the answer......have fun...enjoy.......

Chlorine's mass is not a whole number because of the existence of isotopes of chlorine. Isotopes of chlorine have the same atomic number but with different mass number. The mass of chlorine 35.5 is therefore the average mass of all these isotopes based on each isotope's percent abundance in nature.

A chlorine atom needs only one electron to have a stable outer shell.\n\nLooking at its atomic number, a chlorine atom has the same number of electrons.

1. CCl4 carbon tetrachloride is a colorless liquid.\n2. Zn is the most chemically similar to Cd, because the two elements belong to the same family or column of the periodic table of elements.\n3. Only B and C a representation of Bronsted-Lowry's Acid-Base Theory.  A and E (HCl(g) + NH3(g) --> NH4Cl and Cu2+ (aq) +4NH3(aq) ---> [Cu(NH3)4]2+(aq)) represent a Lewis Acid-Base reaction. D (Al2O3 +2NaOH(aq) + 3H2O(l) --->2NaAl(OH)4 (aq)) is a combination or synthesis reaction.

Arsenic is the metal, but at temperatures much lower than its melting point (not boiling point).  It sublimes at 614 degrees C and melts under pressure at 817 degrees C.\n\nAlthough Iodine has a metallic luster, it is not a metal.  It sublimes (evaporates) near its \nMelting Point of 114 degrees C.\n\nSee the reference below:

"Iodine, it is sublime". (Because it sublimates-goes directly from solid to a gas).\n\nGet an "A".

Look at the electronegativity of both atoms. The electron density is going to be clustered around the more electronegative one. Electronegativity increases as you go up and to the right on the periodic table (noble gases not included), so Fluorine is the most electronegative atom.\n\nSo, the bond between nitrogen and oxygen is polar, but only slightly. The bond between iodine and fluoring is quite polar. The bond between cesium (the least electronegative natural element) and fluorine is so polar, that all the electron density is clustered around the fluorine, making it an ionic bond rather than a covalent bond.

Iodine is the element.\n\nMixture of iodine? quite vague ha.\n\nWell, you've got a lot of choices:\n\nIodine Topical Solution and Iodine Tincture = contains, in each 100 mL, not less than 1.8 g and not more than 2.2 g of iodine (I), and not less than 2.1 g and not more than 2.6 g of Sodium Iodide (NaI).\n\nStrong Iodine Solution and Strong Iodine Tincture = contains, in each 100 mL, not less than 4.5 g and not more than 5.5 g of iodine (I), and not less than 9.5 g and not more than 10.5 g of Potassium Iodide (KI).\n\nNote: Of course these would have different solvents.

The elements Chlorine and Nitrogen are found in their natural, elemental forms of Chlorine gas (Cl2) and Nitrogen gas (N2) in nature, not as atomic Chlorine or atomic Nitrogen.\n \nNitrogen gas makes up the majority of Earth's atmosphere (AKA "air").\n\nChlorine gas is faily easy to produce with electrochemical reactions, or even through standard (non electrolytic) reactions.\n\n\nClorox does NOT contain Chlorine gas.  Amongst other things, the active ingredient in clorox bleach is Sodium Hypochlorite (NaOCl), not "Chlorine".

FeCl3 is a Lewis acid, because the Iron loses electron density because of the chlorines. So it complexes with the lone pair in water on the oxygen atom. In doing so, a proton is released from the water, which then complexes with the other water molecules to make H30+

No, no lead and silicon are elements, not compounds. Neither is made by combining carbon and chlorine. Please do not tell anyone they are, especially someone not very good at chemistry.\n\nCarbon tetrachloride, that's a carbon atom surrounded by four chlorine atoms is a chloride of carbon. It's sort of pyramid shaped. Here's some info on it.

Sodium Chloride is an obvious example, as is Potassium Flouride, Lithium Bromide, or any other combination os the alkali metals and halogens from the periodic table.\n\nThe alkali metals are on the far left column of the table, and halogens are on the column 2nd from the right (next to last).\n\nAll of these combinations are collectively refered to as "salts".\nA salt is an ionic compound which contains a metal cation (+) and a nom-metal anion (-).  It is not a requirement that it be a specific type of metal or a specific type of non-metal though, for example, Iron Oxide is also technically a "salt", but it is more commonly refered to as an "Oxide", a more specific type of salt.\n\nhttp://www.webelements.com/index.html
