Guida verificata passo dopo passo1
Identify the elements involved in the formation of a water molecule: hydrogen (H) and oxygen (O).
Understand the nature of the elements: Hydrogen is a non-metal, and oxygen is also a non-metal.
Recall that covalent bonds are typically formed between non-metal atoms by sharing electrons.
Consider the electron configuration: Oxygen needs two additional electrons to complete its valence shell, while each hydrogen atom needs one electron.
Conclude that the bond formed between the hydrogen atoms and the oxygen atom in a water molecule is a covalent bond, as they share electrons to achieve stable electron configurations.
