Step 1:: Understand the problem
The problem asks for the number of valence electrons in the element Antimony (Sb). Valence electrons are the outermost electrons in an atom and are involved in the formation of chemical bonds with other atoms.
Step 2:: Identify the group of the element
Antimony (Sb) is located in Group 15 (VA) of the periodic table. This group also includes elements such as nitrogen, phosphorus, arsenic, and bismuth.
Step 3:: Recall the pattern of valence electrons in Group 15 elements
Group 15 elements have 5 electrons in their outermost shell.
Step 4:: Determine the number of valence electrons
Since Antimony (Sb) is in Group 15, it has 5 valence electrons.
Step 5:: Select the correct answer
The correct answer is option B: 5.
Final Answer
The number of valence electrons in antimony (Sb) is 5.
