Which part(s) of a water molecule has/have a partial positive charge?
|
|
the two hydrogen (H) atoms
|
|
|
the two oxygen (O) atoms
|
|
|
the one hydrogen (H) atom
|
|
|
the one oxygen (O) atom
|
Explanation:
Detailed explanation-1: -Because oxygen is more electronegative-electron-greedy-than hydrogen, the Ostart text, O, end text atom hogs electrons and keeps them away from the Hstart text, H, end text atoms. This gives the oxygen end of the water molecule a partial negative charge, while the hydrogen end has a partial positive charge.
Detailed explanation-2: -As a result, the water molecule is “polar”, meaning the molecule has an unequal distribution of charge. The oxygen atom pulls the electrons away from the hydrogen atoms resulting in the oxygen atom having a partial negative charge (-
