Bromine. (a) Metal which is liquid at room temperature (i) Iodine (b) Non-metal which is liquid at room temperature (ii) Sodium (c) Non-metal which is solid at room temperature (iii) Mercury (d) Metal which is poor conductor of heat (iv) Bromine (e) A soft metal (v) Lead By signing up, you'll get thousands of. Answer (1 of 4): Iodine is a solid. Room temperature is usually taken as being 25°C. Whereas iodine is found in solid state at room temperature. Chlorine, Cl2, is a gas at room temperature, but bromine, Br2, is a liquid. Why is iodine a solid at room temperature and chlorine a gas, despite being in the same group? Their group number only describes the number of electrons they have in their outer shell. 82.4k+. At this temperature, fluorine and chlorine are gases, bromine is a liquid, and iodine and astatine are solids. 30694095. Its properties are intermediate between those of chlorine and iodine.Isolated independently by two chemists, Carl Jacob Löwig (in 1825) and Antoine Jérôme Balard (in 1826 . Plus, unlike many gases, iodine vapor has a distinct purple color and is easy to see. It is only at temperatures between -7 °C and 59 °C that fluorine and chlorine are gases, bromine is a solid, and iodine is a solid. Br forms diatomic molecules and van der Waals interactions are sufficiently strong. When the temperature gets to 113.7 o C (point 2), the temperature stops rising as the added heat is used to melt solid iodine. ∙ 2009-05-31 10:03:32. Though the subject of using iodine as the liquid-based active cathode material in lithium cells have been explored in the past 14,15,16,17,18,19,20,21,22,23,24, this is the first time iodine in . Why Bromine is liquid at room temperature? The Iodine that you buy in a store as a liquid has been mixed with other chemicals for easy use. Non-metals can be solid, liquid, or gas at room temperature depending upon the . There is therefore a trend in state from gas to liquid to solid down the group. Iodine and astatine are solids at room . Br forms diatomic molecules and van der Waals interactions are sufficiently strong. Approved by eNotes Editorial Team Ask a Question Bromine is a liquid at room temperature and Iodine is a solid. iodine - iodine - Physical and chemical properties: Iodine is a nonmetallic, nearly black solid at room temperature and has a glittering crystalline appearance. 1. It is less reactive than chlorine and more reactive than iodine. This answer is: Iodine is a nonmetallic, nearly black solid at room temperature and has a glittering crystalline appearance. Also, is iodine a solid liquid or gas at room temperature? Is iodine a solid liquid or gas? So the correct option is C. At 25oC, chlorine (Cl2) is a gas whereas bromine (Br2) is a liquid. In halogens, fluorine has fewer electrons and a weaker dispersion force as compared to iodine. One non-metal, bromine, is a liquid at room temperature. It is a fluorinating agent, but is mild enough to store in glass apparatus. Bromine is a liquid because the intermolecular forces are strong enough so that it does not vapourise. It is the lightest element. As iodine has a higher atomic number than chlorine, it also has more electrons in its electron shells. The reason behind this trend is the atomic size because down the group the atomic weight increase that with increasing atomic number as well. Question. Whether a substance is a solid, liquid, or gas . 4.1k+. Its properties are thus intermediate between those of chlorine and iodine. Room temperature is usually taken as being 25°C. Answer (1 of 3): It is most powerful question .Before giving your question ,first we will defined van der waals bond or force,and looked trend of this force in periodic table,also looked the halogens in periodic table In the periodic table the vander waal 'force increase down the group. Astatine (like iodine) would be solid at room temperature. There is therefore a trend in state . Iodine is used as a disinfectant for cleaning surfaces and storage containers and is used in skin soaps and bandages, and for purifying water. Iodine exists as a solid at room temperature because the strength of these forces are in line with iodine's large electron cloud and polarizability. The non - metal which is liquid at room temperature is (a) Carbon (b) Iodine (c) Bromine (d) Chlorine asked Oct 29, 2020 in Matter by Naaji ( 56.8k points) matter Iodine has bp and fp of 184 and 113 C, respectively, so it is a solid at room temperature. At a high enough temperature they will all be gases. This element is a solid. The solution was transferred to a 1 cm quartz cell, the SERS spectra were recorded by scanning the solution with Raman spectrometer and the SERS intensity at 1609 cm −1 was recorded as I 1609cm-1 . Silver however is definitely a solid with strong metallic bonding. 0 Upvotes. The Halogen Which Is Liquid at Room Temperature Is_____. The halogen which is liquid at room temperature is: A. Fluorine. Solution. a. solid b. liquid c. gas By signing up, you'll get. So the dispersion forces (London forces) are strong enough in Br2 to keep it in the liquid state. iii. Some solids can transition directly into the gaseous state, bypassing the liquid state, via a process known as sublimation.At room temperature and standard pressure, a piece of dry ice (solid CO 2) sublimes, appearing to gradually disappear without ever forming any liquid.Snow and ice sublime at temperatures below the melting point of water, a slow process that may be accelerated . Which statement is true regarding fluorine and iodine? The molecules of each substance attract each other through dispersion (London) intermolecular forces. The molecular lattice contains discrete diatomic molecules, which are also present in the molten and the gaseous states. The other non-metals are solids at room temperature, including carbon and sulfur.
