(a)
Interpretation: The electron dot structure of chlorine needs to be drawn.
Concept Introduction: An electron dot structure represents the arrangement of total valence electrons in an element. Here, electrons are represented as dots in pairs around the symbol of an atom of the element.
(a)
Explanation of Solution
The given element is chlorine. The
(b)
Interpretation: The electron dot structure of bromine needs to be drawn.
Concept Introduction: An electron dot structure represents the arrangement of total valence electrons in an element. Here, electrons are represented as dots in pairs around the symbol of an atom of the element.
(b)
Explanation of Solution
The given element is bromine. The atomic number of bromine is 35 and it belongs to group 17 or the halogen family in the periodic table. An atom of bromine has 7 valence electrons. Thus, an electron dot structure of bromine is as follows:
