What is the symbol of the element Bromine?

Appeared in: RRB Nsg. Superintendent-20 July 2019 (Shift-2)

Explanation

The internationally accepted chemical symbol for the element Bromine is Br.
Bromine has an atomic number of 35 and is classified as a halogen, a group of highly reactive nonmetals.
Chemical symbols are abbreviations used to denote chemical elements, typically derived from the element's name in English or Latin.

Option A: B is the chemical symbol for the element Boron, a metalloid with atomic number 5.
Option B: Be is the chemical symbol for the element Beryllium, an alkaline earth metal with atomic number 4.
Option D: Bi is the chemical symbol for the element Bismuth, a post-transition metal with atomic number 83.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Chemical symbols of elements as background academic context rather than a clinical decision trigger.
A solid understanding of basic chemistry, including element symbols, is foundational for pharmacology. Nurses must be familiar with the chemical names of drugs and electrolytes, such as NaCl (Sodium Chloride) or KCl (Potassium Chloride).
Bromine is a halogen, like iodine. Halogen-based compounds like povidone-iodine are essential antiseptics in clinical settings for wound care and surgical preparation.
Historically, bromide salts (compounds containing Br) were used as sedatives and anticonvulsants, highlighting the direct link between elements and medicine.

How to Approach the Question

This is a factual recall question based on fundamental knowledge of chemistry.
First, identify the key term in the question, which is the element 'Bromine'.
Recall the standard one or two-letter chemical symbol for Bromine.
Evaluate the given options to find the correct match. 'Br' is the standard abbreviation for Bromine.
Mentally confirm the other options are incorrect by associating them with their respective elements: B is Boron, Be is Beryllium, and Bi is Bismuth.
