The ions in NaCl are sodium ions (Na+) and chloride ions (Cl-). In a NaCl crystal lattice, sodium atoms lose an electron to form positively charged sodium ions, while chlorine atoms gain an electron to form negatively charged chloride ions.
The cause is the interaction between valence electrons.
Ions form when electrons are transferred between atoms, resulting in a difference in the number of protons and electrons. This creates ions with either a positive charge (cation) or a negative charge (anion) based on the imbalance of electrons.
Metals form cations and non-metals form anions.
Atoms gain electrons to form negatively charged anions. Atoms lose electrons to form positively charged cations.

Ions, charged atoms
unstable atoms
When sodium atoms react with iodine atoms, they undergo a redox reaction to form sodium iodide. Sodium atoms lose an electron to form Na+ ions, while iodine atoms gain an electron to form I- ions. These ions then combine to form sodium iodide crystals.
Because they want to.
No. Atoms of an element lose or gain electrons to form ions.
ions
Negative ions form when atoms gain extra electrons to fill their valence shell. This results in the atom becoming negatively charged.
+1 ions.
Negative ions are formed when atoms accept electrons.
Positive ions (or cations) are formed when atoms lose electrons
Positive ions
