Answer :
Answer:
An atom is known to become an Ion when it undergoes a chemical reaction. This is become chemical reactions occur as a result of loss or gain of electrons.
When this occurs the atom is said to become an ion.
When am atom gains electrons it becomes negatively charged and is referred to as an anion while when it loses electrons it becomes positively charged and is referred to as a cation.
Answer:
When it loses or gains an electron.
Explanation:
A molecule becomes an ion when it loses or gains an electron. Gaining or losing a molecule of ATP doesn’t make a molecule an ion, and it doesn’t matter whether the molecule is in a hypertonic or hypotonic solution. Moving through a semipermeable membrane isn’t a contributing factor to a molecule becoming an ion.
