Bromine is the only nonmetallic element that is liquid at ordinary temperatures. It is a dense, reddish-brown liquid which evaporates easily at room temperature to a red vapor with a strong, chlorine-like odor. Bromine is less reactive than chlorine or fluorine but more reactive than iodine.
How does bromine differ from the other halogens and nonmetals?
Bromine is a member of the halogen group and it is heavy, mobile and a dangerous liquid. ... One of the most important differences between bromine and other non- metals is that bromine is liquid at room temperature . The only other element which is liquid at room temperature is mercury and mercury is a metal.
How are the three forms of bromine different?
Two naturally existing isotopes of bromine exist, bromine-79 and bromine-81 . Isotopes are two or more forms of an element. Isotopes differ from each other according to their mass number. ... The number of protons determines the element, but the number of neutrons in the atom of any one element can vary.
What is the difference between BR and br2?
Bromine is a chemical element in the periodic table which is denoted by Br while Bromide is the anion that forms when bromine abstracts an electron from another electropositive element. Moreover, the key difference between bromine and bromide is that bromide is the reduced form of bromine.
What are 3 properties bromine?
| Atomic number 35 | Electronegativity according to Pauling 2.8 | Density 3.1 g.cm – 3 at 20°C | Melting point – 7.2 °C | Boiling point 58.8 °C |

Is the only liquid nonmetal?
One non-metal, bromine , is a liquid at room temperature.
Are metalloids dull and brittle?
Metalloids are metallic -looking brittle solids that are either semiconductors or exist in semiconducting forms, and have amphoteric or weakly acidic oxides. Typical nonmetals have a dull, coloured or colourless appearance; are brittle when solid; are poor conductors of heat and electricity; and have acidic oxides.
Is BR always br2?
| Br 2 Bromine | Boiling Point 139.2 ° F at 760 mm Hg | Melting Point 19 ° F | Chemical Formula Br-Br |

How many VE does BR have?
Bromine has an electron configuration of 1s22s22p63s23p64s23d104p5 the valence electrons are in the 4s and 4p orbitals giving Bromine 7 valence electrons .
What are the dangers of bromine?
Breathing bromine gas could cause you to cough , have trouble breathing, get a headache, have irritation of your mucous membranes (inside your mouth, nose, etc.), be dizzy, or have watery eyes. Getting bromine liquid or gas on your skin could cause skin irritation and burns.
How long does bromine stay in your system?
Bromide has an elimination half-life of 9 to 12 days , which can lead to excessive accumulation. Doses of 0.5 to 1 gram per day of bromide can lead to bromism.
What is the period of bromine?
| Group 17 −7.2°C, 19°F, 266 K | Period 4 58.8°C, 137.8°F, 332 K | Block p 3.1028 | Atomic number 35 79.904 | State at 20°C Liquid 79 Br |
