Question

a water molecule is held together by __ covalent bonds, meaning there are a total of __ shared electrons in the molecule. a 2,2 b 4,4 c 2,10 d 4,10 e 2,4

Explanation:

Step1: Analyze the structure of water molecule

The chemical formula of water is \(H_2O\). In a water molecule, there are two \(O - H\) covalent bonds.

Step2: Calculate the number of shared electrons

Each covalent bond is formed by sharing a pair of electrons. Since there are two \(O - H\) bonds, the number of shared electrons is \(2\times2 = 4\).

Answer:

E. 2,4
