Sodium chloride has two atoms in the formula unit (NaCl): sodium and chlorine.
Sodium Chloride is a molecule. A molecule contains 2 or more atoms. Each molecule of Sodium Chloride contains 1 sodium atom and 1 chloride atom.
In a sodium chloride crystal, each sodium atom is surrounded by 6 chloride atoms in a regular octahedral arrangement due to the ionic bonding between the sodium cation and chloride anion.
Sodium Atom
Ionic bond
Sodium chloride is a chemical compound, not a mixture.
When a sodium atom and a chlorine atom come into contact, the sodium atom will donate one electron to the chlorine atom, forming a positively charged sodium ion and a negatively charged chloride ion. These ions are then attracted to each other through electrostatic forces, forming an ionic bond and creating a molecule of sodium chloride.
Sodium chloride has ionic bonding, which is the electrostatic attraction between oppositely charged ions (sodium cation and chloride anion). This type of bonding involves the transfer of electrons from one atom to another.
The chlorine atom.
The chemical formula for sodium chloride is NaCl, which indicates that it is made up of one sodium atom and one chlorine atom. Sodium chloride is commonly known as table salt.
A NaCl (sodium chloride) atom contains one sodium (Na) atom and one chlorine (Cl) atom. Sodium has 11 protons and chlorine has 17 protons. They bond together through an ionic bond to form the compound sodium chloride.
One formula mass of the salt sodium chloride.
A "molecule" of sodium chloride, common salt. (Because this is an ionically bonded compound, its molecule is a formal concept only, rather than a unit that can be isolated.).
