You are presented with the question "What can be done to a neutral atom to make positive charges attractive to it?" and the following answer choices: 
- Remove an electron
 - It gets heated up
 - Cool the atom
 - flow of electrons
 - Inject hormones
 - Accelerate the atom
 - adding heat
 - electrically

Now knowing that if a neutral atom loses an electron then an atom with a negative charge will be formed and negative charges are attracted to positive charges, choose the best answer.
