What are the characteristics 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. Bromine has a pungent odour and is irritating to the skin, eyes, and respiratory system.
What are 5 physical properties of bromine?
Its melting point is −7.2°C, 19°F, 266 K and boiling point is 58.8°C, 137.8°F, 332 K. The relative atomic weight is 79.904, and it has a density of (g cm-3) 3.1028. The appearance of an element is reddish-brown, and it has metallic lustre in solid-state. Bromine has 29 known isotopes; it ranges from Br-69 to Br-97.
Is bromine naturally a solid liquid or gas?
Bromine is a naturally occurring element that is a liquid at room temperature. It has a brownish-red color with a bleach-like odor, and it dissolves in water.
What are bromine physical and chemical properties?
Chemical properties of bromine – Health effects of bromine – Environmental effects of bromine

| Vanderwaals radius | 0.165 nm |
Is bromine water aqueous or liquid?
Bromine is a dark reddish-brown fuming liquid with a pungent odor. Denser than water and soluble in water. Hence sinks in water.
Why bromine is a liquid?
Bromine is a liquid because the intermolecular forces are strong enough so that it does not evaporate. Bromine forms diatomic molecules and Van der Waals interactions are sufficiently strong.
What makes bromine a liquid?
Bromine is a chemical element with the symbol Br and atomic number 35. It is the third-lightest halogen and is a volatile red-brown liquid at room temperature that evaporates readily to form a similarly coloured vapour. Its properties are intermediate between those of chlorine and iodine.
Does bromine have chemical properties?
Chemical Properties Bromine can exist at multiple oxidation states, so it can form a wide variety of compounds. It is a strong oxidizing agent and forms compounds with metals (FeBr3), non-metals (HBr), and even other elements in group 17 elements (BrF, BrCl, Br2).
Is bromine a reactive element?
It bonds easily with many elements and has a strong bleaching action. Bromine is highly reactive and is a powerful oxidizing agent in the presence of water.
How is bromine water formed?
Bromine water is a yellow mixture solution with high oxidizing property, prepared by dissolving diatomic bromine (Br2) in water (H2O). Bromine water solution can be prepared in the chemistry lab by direct mixing of fumes of bromine and water.
Is bromine a solid?
At standard conditions for temperature and pressure it is a liquid; the only other element that is liquid under these conditions is mercury.
Is bromine liquid or aqueous?
Bromine is a dark reddish-brown fuming liquid with a pungent odor. Denser than water and soluble in water.
What compounds can bromine form?
Bromine is too reactive to exist as a free element in nature. Instead, it occurs in compounds, the most common of which are sodium bromide (NaBr) and potassium bromide (KBr). These compounds are found in seawater and underground salt beds.
Is bromine a metal or nonmetal?
nonmetal
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.
Is bromine reactive or nonreactive?
Bromine is a very reactive element. While it is less reactive than fluorine or chlorine, it is more reactive than iodine. It reacts with many metals, sometimes very vigorously. For instance, with potassium, it reacts explosively.
Is bromine aqueous or liquid?
liquid
Bromine is a chemical element with the symbol Br and atomic number 35….
| Bromine | |
|---|---|
| Phase at STP | liquid |
| Melting point | (Br2) 265.8 K (−7.2 °C, 19 °F) |
| Boiling point | (Br2) 332.0 K (58.8 °C, 137.8 °F) |
Is bromine transparent translucent or opaque?
It is somewhat transparent, even though it is a dark, reddish color. It evaporates easily under normal conditions. Along with mercury, bromine is one of two elements found to be a liquid at room temperature.
Why is bromine a liquid?
Bromine, on the other hand, has a slightly higher molecular weight than fluorine and has stronger intermolecular interactions, thus it persists as a liquid at ambient temperature.
What is bromine and why is it dangerous?
Bromine is dangerous because it is a corrosive liquid and a toxic, choking gas. Bromine is a chemical that is toxic to humans and has a wide range of side effects from contact or ingestion. The use of bromine in industrial applications and manufacturing has exposed some people to unusually high levels.
What are the physical and chemical properties of bromine?
– Fluorine – Chlorine – Bromine – Iodine – Astatine
What does bromine do to the body?
If bromine touches the skin, it can cause lesions and sores that can be very serious. It also has a negative effect on the thyroid. There are reports that the effects of bromine include health issues ranging from kidney and liver damage to the possibility that it can cause cancer.
What are some cool facts about bromine?
Bromine (Br) has an atomic number of thirty-five. It is a heavy dark brown liquid, the only non-metallic element that is a liquid. Interesting Bromine Facts: Bromine was discovered by Antoine J Balard in 1826. It was used for important purposes long before it was formally discovered. Two separate scientists isolated bromine, including one who
