The periodic table provides enough information to determine the bonding properties of many elements. Using only the information available in the periodic table, consider the elements magnesium and nitrogen.

Determine the charge on these two elements when they freely form ions, and explain why and how these charges form.

Determine the formula for the compound formed by the combination of these two ions, and explain why this is the chosen formula. Name this compound.

the enthalpy of formation of water is given as -285.8kj/mol, which states that the enthalpy of formation is negative.

negative enthalpy of formation indicates that the heat is released during the reaction process. the heat is released from reaction to the surroundings the enthalpy is expressed with a negative sign with the energy given out in the reaction process.

the formation of water takes place by giving out heat which is -285.8 kj/mol.
