The water dissolves the salt because the water molecules are able to interact with the salt-forming particles, called ions. When the water Interacts with the trainers of the salt ions, the solid salt crystal structure Suffers breakdown, until the trainers of the salt ions are completely surrounded by water molecules. At this time the salt is fully dissolved by water.

Answer : The correct option is, 
Explanation :
The given element bromine belongs to the group 17 and period 4. The symbol of bromine is, Br.
The atomic number of bromine = 35
The total number of electrons present in bromine element = 35
Electronic configuration : It is defined as the arrangement of electrons around the nucleus of an atom.
Hence, the correct electronic configuration of bromine is,
Monosaccharides are the simplest unit of carbohydrates. They're composed of carbon, hydrogen, and oxygen atoms, and they cannot be broken down further since they are already in their simplest form. Their general formula is (CH2O)n, where n is any number equal or greater than 3.
Reproducibility is a major principle of the scientific method. It means that a result obtained by an experiment or observational study should be achieved again with a high degree of agreement when the study is replicated with the same methodology by different researchers.
