For the following questions consider a water molecule, h2o. a. what type of bond is formed between the oxygen and the hydrogen atoms? b. describe how these bonds form. c. explain why there are two hydrogen atoms for each oxygen atom.

This is about type of bonds between elements that make water molecules.

A) Polar Covalent Bond

B) Because of unequal sharing of valence electrons

C) Because left hand side must balance out with right hand side

1(O₂) + 2H₂ → 2H₂O

In chemical equations, the left hand side must balance out with the right hand side. Thus, that's why the right hand side has 2 hydrogen atoms for one oxygen atom.

sodium (na), for example, has one electron in its valence shell. this is an unstable state because that valence shell needs eight electrons to be full. in order to fill its valence shell, find a way to add seven electrons to its valence shell
