forms a covalent bond
APEX:They form an ionic compound.
An ionic bond
Common salt is NACl and contains both sodium and chlorine. It can therefre be used as a source of chlorine (electrolysis) and sodium compounds.
The sodium atom gives an electron to the chlorine atom to make the sodium and chloride ions respectively. Then they form ionic bonds forming sodium chloride.
A sodium ion is a sodium atom missing one electron. A chlorine ion is a chlorine atom with an extra electron. A salt molecule is a sodium ion stuck to a chlorine ion.
positively
When in elemental form, atoms of sodium lose electrons to atoms of chlorine, forming ions (this occurs in a 1:1 ratio). These ions are attracted by the electric difference between them and form a salt.
In presence of chlorine, sodium atoms will discharge electrons to give sodium ions to combine with chloride ions followed by forming a lattice of sodium chloride.
Sodium chloride is formed from sodium and chlorine.
The salt molecules are "torn apart" by the water, and are reduced to sodium (Na+) and chlorine (Cl-) ions. It is the ions that go into solution and "float around" there. Note that elemental sodium and elemental chlorine are not what is in solution. The ions are. Salt, sodium chloride, is an ionic molecule; an ionic bond holds salt together.
An ionic bond
Hydrogen and Oxygen H20 is the element compound of water.
Common salt is NACl and contains both sodium and chlorine. It can therefre be used as a source of chlorine (electrolysis) and sodium compounds.
Sodium - Na+ Chlorine - Cl-
Your phrasing is slightly off. It does not require ions to form sodium chloride; that compound is made from atoms of sodium and chlorine (one of each). Once the compound is formed, the sodium and chlorine then become ions, Na+ and Cl-.
Sodium chloride is a compound of sodium and chlorine formed by ionic bonding of sodium ions and chlorine ions.
The ions are neutralised (and therefore are no longer ions). The new particle is a stable form of both sodium and chlorine, in other words chloride and sodium. These forms have full valence shells and will not react like their former disposition.
sodium gives one electron to form sodium cation. chlorine accepts one electron to form chloride anion sodium chloride consists of an array or sodium ions and chloride ions
