What is a covalent bond?
A relatively strong chemical link between two atoms in which electrons are shared between them.

What is this arrangement is known as?
Polar water molecule
7 of 10
There is electrostatic attraction...
Between the positively charged region of one water molecule and the negatively charged region of a neighbouring one, giving rise to weak bonds called hydrogen bonds.

What is a hydrogen bond?
A relatively weak link between two atoms in which a weakly negative atom attracts another weakly positive atom.
