What atoms are likely to lose electrons to form cations

Hey Jose! Thanks for asking a question here on . 

⚪ Potassium 
⚪ Magnesium 
⚪ Sodium (aka Na) 
⚪ Lithium (aka Li)

These are all atoms that are likely to lose electrons in order to form cations. Hope this helps. -UF aka Nadia

Alkali metals are likely to lose electrons to form cations because they only have one valence electron, which makes it easiest to lose.

The total number of electrons is 14

You would be correct, boiling water does disinfect contamination.    the property of disinfecting means to kill  germs, bacteria and other pathogens or contamination  that might cause an infection or cause a person to become sickly. a couple methods of disinfecting are using soap, other cleaning supplies or by simply "boiling" the contaminate.  the reason why boiling water disinfects certain attributes is because some cells cannot survive the heat and pressure.
