Two hydrogen atoms and oxygen atom are going through a chemical reaction to form water what would they say to each other as the chemical reaction occurs

The point is that they are going to share electrons and form a covalent bond. So I think what they might or should say to each other is,

"We have decided that we are going to share our electrons and have bonded together in order to make a molecule of water".

ca has a crystalline lattice with positive ions (since it is a metal, metals are positively charged) and electrons flow freely in its structure since the ca atoms have a large nuclear radius so the electrons are not tightly held, therefore the electrons can flow freely since they are not being highly attracted by the nucleus. moreover, one of the properties of metals are that they are conductors of electricity, thus proving ca is the element.
