Fluorine is a gas at STP while iodine is solid because fluorine has a higher average kinetic energy than iodine. Temperature affects the phase of a substance, in that, when we heat a substance, it's particles gain more kinetic energy, vibrate faster and move more apart from each other.
Is iodine a solid?
Iodine is a nonmetallic, nearly black solid at room temperature and has a glittering crystalline appearance. The molecular lattice contains discrete diatomic molecules, which are also present in the molten and the gaseous states.
Is fluorine a solid liquid or gas at room temperature?
Elemental hydrogen (H, element 1), nitrogen (N, element 7), oxygen (O, element 8), fluorine (F, element 9), and chlorine (Cl, element 17) are all gases at room temperature, and are found as diatomic molecules (H2, N2, O2, F2, Cl2).
Why is iodine a solid at room temp?
Despite intermolecular forces being a weak individual force of attraction, collectively they are very strong and the numerous forces between iodine molecules means that more heat energy is required to break these intermolecular forces and separate the molecules therefore iodine is a solid.
Which statement explains why Br2 is a liquid at STP and I2 is a solid at STP?
Which statement explains why Br2 is a liquid at STP and I2 is a solid at STP? 1. Molecules are Br2 are polar, & molecules of I2 are nonpolar.
Why is fluorine a gas bromine a liquid and iodine a solid at room temp
What compound has the strongest intermolecular forces?
HF (boiling point = 19.4 degrees Celsius) has the strongest intermolecular forces.
Which claim below explains why at STP bromine is a liquid and iodine is a solid?
As we move from fluorine to iodine, the electrons are further from the nuclei so the electron clouds can more easily distort. The London dispersion forces become progressively stronger. ... 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.
Does iodine dissolve in water?
Iodine dissolves easily in chloroform and hexane but does not dissolve in water. ... Although non-polar molecular iodine cannot dissolve in water, it reacts with iodide ion to form something that can: the triiodide ion.
Why chlorine is gas but iodine is solid?
Explanation: Iodine is present in solid form at room temperature while chlorine is a gas at room temperature because of the difference in intermolecular forces that act on between individual molecules. Iodine has atomic number 53 while chlorine has 17, so iodine has more electrons in its electron shells.
What is the state of phosphorus at room temperature?
Phosphorus (P), nonmetallic chemical element of the nitrogen family (Group 15 [Va] of the periodic table) that at room temperature is a colourless, semitransparent, soft, waxy solid that glows in the dark.
Why is fluorine a gas room temperature?
Fluorine molecule has very little molecular weight and the strength of intermolecular forces is weak and hence it exists as a gas at room temperature.
Is Iodine a gas at room temperature?
At room temperature, it is a colourless gas, like all of the hydrogen halides except hydrogen fluoride, since hydrogen cannot form strong hydrogen bonds to the large and only mildly electronegative iodine atom.
How can I tell if I am allergic to iodine?
- itchy rash that comes on slowly (contact dermatitis)
- hives (urticaria)
- anaphylaxis, which is a sudden allergic reaction that can cause hives, swelling of your tongue and throat, and shortness of breath.
What is the formula for iodine solid?
Iodine | I2 - PubChem.
Is iodine solid or liquid?
As a pure element, iodine is a lustrous purple-black nonmetal that is solid under standard conditions. It sublimes (changes from a solid to a gaseous state while bypassing a liquid form) easily and gives off a purple vapor.
Is iodine a base or acid?
Iodine is neither an acid NOR a base.....
What Colour is iodine solution?
A solution of iodine (I2) and potassium iodide (KI) in water has a light orange-brown color.
What color is iodine in water?
This trick works because iodine is brown when dissolved in water and purple when dissolved in oil. Pure iodine is violet, but when it's dissolved in water, it accepts an electron from the oxygen atom, affecting how it absorbs light.
Why is iodine not very soluble in water?
Non-polar Iodine is not very soluble in water. An intermolecular bond between an induced dipole (I2) and a polar bond in water is not very strong compared to the hydrogen bonds in water. The water molecules would rather remain hydrogen bonded to each other, then to allow an iodine molecule come between them.
Does iodine form a basic solution in water?
Explanation: Pure iodine has a violet colour. ... However, iodine can also act as a Lewis acid (an electron acceptor). The interaction with the oxygen end of water becomes more important, because the lone pair electrons on water make it a Lewis base.
What color is Br2?
Bromine is a dark reddish-brown fuming liquid with a pungent odor.
Why is H2 a gas and I2 solid?
are the only forces between nonpolar molecules. Why is I2 a solid while H2 is a gas? ... Only non-polar molecules have instantaneous dipoles.
Is iodine a metal?
Iodine is a nonmetallic, nearly black solid at room temperature and has a glittering crystalline appearance. The molecular lattice contains discrete diatomic molecules, which are also present in the molten and the gaseous states. Above 700 °C (1,300 °F), dissociation into iodine atoms becomes appreciable.
