Answer:
15 protons
8 electrons in valence shell after accepting 3 electrons
Neutral/no charge before accepting 3 electrons
-3 charge after accepting 3 electrons
It would move due to it not being<span> the same speed and in the same direction so it is acted upon by an unbalanced force.</span>
So the question ask to separate the reaction of the element if your problem into its component half reaction and the best answer or the elements are the following: (Cs-> Cs+ + 1e-) x2 and <span>2e-+Cl2->2Cl-. I hope you are satisfied with my answer and feel free to ask for more </span>

Answer:
The metal is most likely Sodium.
Explanation:
Iron is not soft enough to be cut with a knife and will not react violently with water. When Iron reacts with water it just slowly rusts.
Copper is somewhat malleable, however, does not really react with water and only forms an oxide layer in the air.
Sodium is soft enough to be cut with a knife (I know this because I have worked with it and seen people work with it). It is also an alkali metal which are known to explode when in water.
Gold is malleable but does not really react with anything and is considered inert.
