What is the valency of bromine

What is the valency of bromine?

The number of valence electrons in an element’s outermost shell is known as its valency. Bromine has an atomic number of 35 and is a member of the halogen family. Bromine has seven valence electrons, and its valency is one.

The given element is bromine and atomic number is 35.

The symbol of the bromine element – Br.

Electronic configuration: 1s22s22p63s23p64s23d104p5 or [Ar]4s23d104p5.

The valency of bromine – +1.

Bromine is a chemically reactive metal that is never pure in nature, as it reacts readily and strongly with alkali metals due to its 7 valence electrons and high electron affinity.

Occurrence:

Bromine is too reactive to exist naturally as a free element. Sodium bromide (NaBr) and potassium bromide (KBr) are the most prevalent chemicals that include it (KBr). Seawater and subsurface salt deposits contain these chemicals.

The physical properties of bromine are:

• It has a melting point of 7.2°C (19°F) and a boiling temperature of 58.8°C (137.8°F) and 332 K. 
• It has a relative atomic weight of 79.904 and a density of 3.1028 (g.cm-3)
• In its solid state, an element has a reddish-brown color with a metallic sheen. 
• Bromine is divided into 29 isotopes, ranging from Br-69 to Br-97.

Chemical properties of bromine:

• Due to its position on the periodic table, it is less reactive than fluorine’s chlorine but more reactive than iodine. 
• Despite the fact that it is in the same series as chlorine and fluorine, it is more reactive than them. However, because iodine is heavier than bromine, bromine is less reactive. It is extremely toxic to humans. 
• When it comes into contact with human skin, it can cause serious burns. Bromine is a bleaching agent as well. 
• When exposed to air, it emits a heavy reddish brown fume. Bromine fumes are extremely harmful to the tissues of the nose and throat.
