The bromine atom forms Br- ion and the Lithium atom forms Li+ ion .
Thus , the bromine and lithium share each one electron and pairing occurs ,and forms ionic bond .the compound which they form is LiBr (lithium bromide ) .
Lithium bromide :
It is hygroscopic white solid . it is soluble in water .
Its solubility in water increases as the temperature increases .
It is also soluble in organic solvents . it is flammable .
What is condensed electron configuration ?
It contains the symbol of the nearest , smaller noble gas in the square brackets and then the symbols of the occupied orbitals which contains valance electrons .
Example of condensed electron configuration is given by ,
in case of iron the electronic configuration is 1s2 2s2 2p6 3s2 4s2 3d6 .
Thus , the condensed electron configuration of iron is [Ar] 3d6 4s2 .
What is Lewis dot structure ?
Lewis dot structure also called as Lewis dot diagrams , Lewis dot formula.
it is a diagrammatic way of showing the bonding between elements , atoms and molecules . it also shows the bonding between the lone pairs of electrons .
This method usually done to satisfy the octet of the atoms and molecules.
There is sharing pairing of electrons occurs between the atoms and molecules .
