Step 1:
Step 2:: Understand the problem
To solve this problem, we need to know the position of iodine in the periodic table or its atomic number.
Step 3:
Step 4:: Find the atomic number of iodine
Iodine is the 53rd element in the periodic table, so its atomic number is 53.
Step 5:
Step 6:: Recall the significance of an element's atomic number
The atomic number of an element is the number of protons (and electrons) in a neutral atom of that element.
Step 7:
Step 8:: Identify the number of valence electrons
Valence electrons are the outermost electrons in an atom and are involved in forming chemical bonds. For main group elements, the number of valence electrons is equal to the element's group number in the periodic table. Iodine is in group 17 (or VIIA), so it has 7 valence electrons.
Final Answer
An iodine atom has 7 valence electrons.
