No, boric acid can still be very dangerous to humans, animals, and children. It may requires a lot of it for a lethal dose, but there are also several side effects of exposure to boric acid. Many of the insecticides that contain boric acid will contain a sweetener, such as sugar, to attract insects.
Within a water molecule is covalent bonds. between water molecules are hydrogen bonds.
The water molecule is formed from two hydrogen atoms and one oxygen atom. The bonding angle of the two hydrogens is almost 105 degrees rather than 180 degrees which would make the molecule symmetrical. This causes it to be dipolar, giving it a positive and negative side which accounts for its unique properties. This allows the formation of hydrogen bonds between adjacent molecules.
