- …The answer is Bromine because the question clearly states, at room temperature this halogen is a liquid, and on any periodic table, bromine is a different colour to the other elements showing that it is a liquid or it melts close to room temperature.

Halogen lamp Because of this, a halogen lamp can be operated at a higher temperature than a standard gas-filled lamp of similar power and operating life, producing light of a higher luminous efficacy and color temperature. The small size of halogen lamps permits their use in compact optical systems for projectors and illumination.

Elements Bromine is a halogen (Group 7 or 17 element). It is one of the few elements liquid at room temperature. Bromine has a melting point of -7 °C and a boiling point of 59 °C. A reddish-brown very irritating poisonous vapor comes from the liquid.

Why are oils liquid at room temperature? trans fat molecules can stack more easily (like saturated fats) and have higher melting points, so are more likely to be solid at room temperature (like margarine). the more unsaturated a fat is, the more disoraganized the molecules are (they don't stack easily). they have lower melting points and are more likely to be liquid at room temperature. this is the case for oils.

- Though tepidly supported by the Opposition parties, Ottawa's position has widely been seen as pandering to the large Ukrainian-Canadian vote, and many on the left and right have attacked the ultra-nationalist tilt of the democratic groups in Ukraine or called for isolationism to be the only proper Canadian stance.

Predicting properties The halogens show trends in physical properties as you go down the group. Melting point and boiling point. The halogens have low melting points and low boiling points. This is a typical property of non-metals. Fluorine has the lowest melting and boiling points. The melting and boiling points then increase as you go down the group.

What are diatomic gases? 2. Because some of the diatomic elements are gases that all gaseous elements (or even molecules) must be diatomic. Only five of the diatomic molecules are gases at room temperature. Bromine is liquid and iodine is a solid at room temperature. All noble gases are monoatomic.

Gaseous elements at room temperature? Group VIIIA (new Group 18) are called the noble gases. They used to be called the inert gases, but Neil Bartlett at UC, Berkeley showed that the noble gases could be made into compounds. Their reactivity is minimal. The noble gases are; Helium, Neon, Argon, Krypton, Xenon, and Radon. Radon is toxic, as it is radioactive. The other elements that are gases at room temperature are: fluorine, F2; chlorine, Cl2; oxygen, O2; nitrogen, N2; and hydrogen, H2. All these gases are diatomic. The halogens, fluorine and chlorine, are highly reactive, and very toxic. Oxygen and nitrogen are reactive, or can be made to react. They are not toxic per se. Hydrogen is, of course, very reactive. Hydrogen and nitrogen are not toxic, but they will suffocate you, as would the noble gases, if you ingested pure forms of them, and your oxygen supply was quenched.

Halogen Elements and Properties Location of the Halogens on the Periodic Table. The halogens are located in Group VIIA of the periodic table, and are a particular class of nonmetals. The halogen elements are fluorine, chlorine, bromine, iodine, astatine, and ununseptium. Properties.These reactive nonmetals have seven valence electrons.As a group, halogens exhibit highly variable physical properties.Halogens range from solid (I 2) to liquid (Br 2) to gaseous (F 2 and Cl 2) at room temperature.he chemical properties are more uniform. The halogens have very high electronegativities. Fluorine has the highest electronegativity of all elements. The halogens are particularly reactive with the alkali metals and alkaline earths, forming stable ionic crystals.

The Halogens They lack only one electron to form a complete shell or subshell, and are extremely active chemically. Chemical activity increases as you move upward in the group, fluorine being the most active element in the Periodic Table. At room temperature, fluorine and chlorine are gases, bromine is liquid, and iodine is solid.They form diatomic molecules in the pure state.
