Iodine is further down group 7 than chlorine. Their group number only describes the number of electrons they have in their outer shell. How to solve: Why is iodine a solid at room temperature? By signing up, you'll get thousands of step-by-step solutions to your homework questions. Although liquid mercury (Hg) has been known since antiquity, the formation of stable solid nano forms of Hg at room temperature has not been reported so far.

What is the temperature (in K) in a 74.7 mL bulb that contains 0.293 g of {eq}I_2 Most ionic compounds are solid at room temperature because they have high melting points due to the strong electrostatic forces between them.

X forms two oxides which are also formed during the thermal decomposition of ferrous sulphate crystals and are the major air pollutants. (a) Identify the element X (b) Write the electronic configuration of X 2008-01-26 Although liquid mercury (Hg) has been known since antiquity, the formation of stable solid nano forms of Hg at room temperature has not been reported so far. Here, for the first time, we report a simple sonochemical route to obtain solid mercury nanoparticles, stabilized by … To boost the energy density as well as address the safety issues, an effective strategy is to replace the liquid electrolytes with solid-state electrolytes (SSEs). However, the current SSEs usually show low ionic conductivity at room temperature and large interfacial impedance with electrodes, which hinders the operation of the all-solid-state lithium batteries (ASSLBs) at room temperature. In The reason iodine, I2, exists as a solid at room temperature, while bromine, Br2, exists as a liquid at the same temperature, is because:Iodine exhibits hydrogen bonding, while bromine exhibits only London dispersion forces.Iodine molecules create stronger London dispersion forces than do bromine room temperature at a wavelength, λ = 2.40 Å. The observed data are shown as dots and the calculated pattern is shown as a solid line. Allowed Bragg peaks are indicated by vertical bars. Supplementary Material (ESI) for Chemical Communications This journal is (c) The Royal Society of Chemistry 2009 2018-05-15 Solid hydrogen is the solid state of the element hydrogen, achieved by decreasing the temperature below hydrogen's melting point of 14.01 K (−259.14 °C; −434.45 °F).

In solid form it is dry ice. For example, water at an average heat (temperature) of -10C is ice. At 40C it is water, and above 100C it is steam. This is, of course, assuming that pressure is the standard (1 atm) and volume is constant.
