The oxygen atom has 4 valence electrons. Valence electrons are the electrons found in the outermost shell of an atom. These are the electrons that participate in chemical reactions during bonding. Since 4 electrons make up 2 pairs, an oxygen atom is capable of making <em>2 covalent bonds</em>.
The only thing you need to put the followings into correct order is to remember that the smalles mass - the less volume it has. So, accordnig to this, the order should be like that : An ice crystal- A water molecule-An oxygen atom-The electron cloud-<span>An oxygen nucleus. Hope you will find it helpful!</span>
