sir/ madam,

is it true that if no of bonds in an atom increases then the atom acquires a positive charge on it and when it loses one bond it acquires a negative charge on it ?

why does it happen so?

Expert Answer:

Dear Student,
 
When number of bond increases it acquires poistive charge it happens in ions like- NH4 , H3O+ 
Number of bonds are increased because one extra atom is attached with and one atom from lone pair is released.
 
For Example in NH3 - One lone pair and 3 bonds are present
In NH4 ion-   One electron from the lone pair is attached one new H and positive charge is due to release of one electon from N. 
It is the only posssibility when octet of N is complete with this positve charge. 
 
 
For negative charge also, To complete the octet of central metal atom one less bond type of structure is formed with negative chargee.
