So here are the two different causes of the force of attraction in a chemical bond. The two different causes of the force of attraction would be the <span>attraction between the p+ nucleus of one and the e- of another atom and the attraction of a positive ion and a negative ion. Hope this is the answer that you are looking for. </span>
ANSWERS:
Group 2 metal carbonates, nitrates and hydroxides decompose to heat to give the corresponding metal oxide and release CO2, NO2 and O2, and H2O respectively. The thermal stability increases down the group as theionic character of the compounds increases down the group.
