Q: What is the coordination number of hydrogen in the complex ion [H2O]2+?
Solution: In the complex ion [H2O]2+, the coordination number of hydrogen is 2.
Steps: 5
Step 1: Understand what a coordination number is. It refers to the number of atoms or ions that are bonded to a central atom in a complex.
Step 2: Identify the central atom in the complex ion [H2O]2+. In this case, the central atom is oxygen (O) in the water molecule (H2O).
Step 3: Look at the hydrogen atoms in the water molecule. Each water molecule (H2O) has 2 hydrogen atoms.
Step 4: Since there are 2 water molecules in the complex ion [H2O]2+, we have a total of 2 (from the first H2O) + 2 (from the second H2O) = 4 hydrogen atoms.
Step 5: However, the coordination number refers to how many hydrogen atoms are directly bonded to the central atom (oxygen). In this case, each water molecule contributes 2 hydrogen atoms, but they are not counted separately for coordination. Therefore, the coordination number of hydrogen in the complex is 2.
