Complete each of the following statements for a molecule of H₂S: c. The number of atoms attached to the central S atom is _______.

Verified step by step guidance

1. Identify the central atom in the molecule H₂S.
2. Recognize that the central atom is usually the less electronegative atom, which is sulfur (S) in this case.
3. Count the number of hydrogen (H) atoms bonded to the sulfur (S) atom.
4. Note that there are two hydrogen atoms bonded to the sulfur atom in H₂S.
5. Conclude that the number of atoms attached to the central sulfur atom is 2.

Key Concepts

Molecular Structure

Molecular structure refers to the arrangement of atoms within a molecule, including the types of bonds and the spatial orientation of the atoms. In H₂S, the central sulfur (S) atom is bonded to two hydrogen (H) atoms, which influences the molecule's shape and properties. Understanding molecular structure is essential for predicting how molecules interact and behave in different environments.

Valence Electrons

Valence electrons are the outermost electrons of an atom that are involved in forming bonds with other atoms. Sulfur has six valence electrons, and in H₂S, it shares two of these with two hydrogen atoms, allowing for the formation of two covalent bonds. This concept is crucial for understanding how many atoms can bond to a central atom and the resulting molecular geometry.

Coordination Number

Coordination number refers to the number of atoms, ions, or molecules that are bonded to a central atom in a complex or molecule. In the case of H₂S, the coordination number of the sulfur atom is two, as it is bonded to two hydrogen atoms. This concept helps in understanding the bonding capacity of an atom and its implications for molecular shape and reactivity.
