The key difference between bromine and mercury is that bromine is the only halogen that is in a liquid state at room temperature , whereas mercury is the only metal that is in a liquid state at room temperature. Both bromine and mercury can be found in their liquid state at standard temperature and pressure conditions.
What is special about bromine?
Smelly element No. 35, bromine, is a fairly abundant element but has a rare property: it is the only nonmetal to exist in liquid form at room temperature , and one of only two elements (the other being mercury) that is liquid at room temperature and pressure. ... Bromine is very harmful to the atmosphere.
What do bromine and mercury have in common?
So the two liquid elements, Bromine and Mercury, have atoms that can move around each other , but not disperse at room temperature. With enough heating or cooling, either element can change state to a gas or solid.
What is unusual about the elements mercury and bromine?
Mercury has a special electron configuration that means the bonds between the mercury atoms are much weaker than the bonds of other metals, so it’s liquid at room temperature instead of solid. Bromine just happens to have a boiling point above room temperature – it’s not unusual for its group, or anything.
Why are mercury and bromine liquid at room temperature?
Liquid Elements at 25°C
Mercury is the only metal that is a liquid at room temperature. ... Bromine is a liquid because its outer electrons are distant from its nucleus . So, bromine atoms are easily influenced by intermolecular forces, making the element a liquid rather than solid at room temperature.
What is the difference between bromine and mercury?
Bromine is a nonmetal while mercury is a metal. The key difference between bromine and mercury is that bromine is the only halogen that is in the liquid state at room temperature , whereas mercury is the only metal that is in the liquid state at room temperature.
Is BR a bromine?
Bromine is a chemical element with symbol Br and atomic number 35. Classified as a halogen, Bromine is a liquid at room temperature.
What are three interesting facts about bromine?
- Bromine is a chemical element on the periodic table.
- Bromine is a liquid and the third-lightest element in the halogen group.
- Bromine has a reddish-brown color in its pure form.
- Bromine has an odor that most humans find foul.
- The symbol for bromine is Br.
- The atomic number for bromine is 35.
Where is bromine used in daily life?
Bromine is used in many areas such as agricultural chemicals, dyestuffs, insecticides, pharmaceuticals and chemical intermediates . Some uses are being phased out for environmental reasons, but new uses continue to be found. Bromine compounds can be used as flame retardants.
What does bromine do to the human body?
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 .
Is bromine a carcinogen?
Bromine is not listed as a carcinogen by the International Agency for Research on Cancer (IARC) [8]. Bromine is a gas and, therefore, inhalation exposure is the most relevant route of exposure to humans [6]. Other routes of exposure are minimal.
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 color of bromine?
Physical and chemical properties
Free bromine is a reddish brown liquid with an appreciable vapour pressure at room temperature. Bromine vapour is amber in colour.
What happens if mercury touches you?
Mercury is a very toxic or poisonous substance that people can be exposed to in several ways. If it is swallowed, like from a broken thermometer, it mostly passes through your body and very little is absorbed. If you touch it, a small amount may pass through your skin , but not usually enough to harm you.
Which two elements are liquid * A mercury and bromine B mercury and carbon dioxide C bromine and water?
So, the metal which is a liquid at standard temperature will be Mercury (Hg). And the non-metal which is liquid at standard temperature is Bromine (Br). Hence, the liquid elements are mercury(Hg) and bromine(Br) .
Can bromine be used in a thermometer?
Note: Bromine is liquid at room temperature but it is not used in the thermometers . This is because the mercury has low specific heat and it does not stick to the walls of the capillary. However, the bromine does not exhibit these properties. There are non-mercury based thermometers.
