chlorine
Chlorine becomes a negative ion in the process of bonding; ionization and bonding are simultaneous, so no, it does not happen before bonding.
No, aluminum does not become a negative ion; like all metals, it forms a positive ion.
No
No, nitrogen does not become a negative ion before bonding. Nitrogen typically forms covalent bonds, in which it shares electrons with other atoms.
It becomes a negative ion.
Al4Cl The compound name is Aluminum Chloride. Al=3- Cl=1+ Chlorine has 7 valence electrons and gains one to become stable making it a positive one charged ion. Aluminum has 3 valence electrons and loses three to become stable making it negative three charged ion.
Sodium has only 1 outer electron to lose to become stable. Chlorine has only 1 electron to gain to become stable. So 1 bonding with 1 is the most energetically favorable proportion.
The bonding is electrostatic attraction between positive and negatively charged ions. For example in common salt, sodium chloride, sodium atoms have lost 1 electron to become Na+ and chlorine atoms have gained one electron to become Cl-.
when sodium valence electron is transferred to chlorine , both atoms become ions . the sodium atom becomes a positive ion . the chlorine atom becomes a negative ion .
when sodium valence electron is transferred to chlorine , both atoms become ions . the sodium atom becomes a positive ion . the chlorine atom becomes a negative ion .
Sodiumbeing in group 1 needs to loose 1e- to become stable. Chlorine being from group 17 needs to gain 1e- to become stable. Sodium gives its extra electronto the chlorine atom. Now both have 8 electrons in their valence and are stable. The sodium gets a positive charge because it lost and electron. The chlorine gets a negative charge because it gained an electron.This creates an ionic bond
The most common bounds chlorine accepts are with Alcaline metals. They have only one valence electron, which chlorine would gladly steal so that his last orbital becomes full of electrons. This way both become stable, and they would form a very strong ionic compound.
