You are presented with the question "Ice crystals are formed when a neutral atom does what?" and the following answer choices: 
- adding heat
 - vaporization
 - flow of electrons
 - loses an electron
 - It remains dormant
 - It gets heated up
 - heating liquids
 - evaporation

Now knowing that if a neutral atom loses an electron then an atom with a negative charge will be formed and ice crystals that are formed have a negative charge, choose the best answer.


 

    loses an electron
