How do atoms form ions?

Can you explain how atoms form ions?

Sure! Atoms form ions by gaining or losing electrons. When an atom loses an electron, it becomes positively charged, and when it gains an electron, it becomes negatively charged.

What causes an atom to lose or gain electrons?

Atoms lose or gain electrons to achieve a full outer shell of electrons, which is more stable. This often happens during chemical reactions.

Can you give me an example of an ion?

Of course! A common example is sodium (Na), which loses one electron to form a sodium ion (Na+), and chlorine (Cl), which gains an electron to form a chloride ion (Cl-).

Are there different types of ions?

Yes, there are two main types of ions: cations, which are positively charged, and anions, which are negatively charged.
