Ascientist calculated the energy required to break bonds in two unknown compounds, a and b. one compound has a covalent bond, and the other has an ionic bond. the table shows a record of these values. bond energy compound a compound b 769 kj/mol 432 kj/mol based on the table, which of the following statements is true? compound a is covalent because transfer of electrons makes relatively stronger bonds. compound b is covalent because sharing of electrons makes relatively weaker bonds. compound a is ionic because sharing of electrons makes relatively stronger bonds. compound b is ionic because transfer of electrons makes relatively weaker bonds.

Compound B is covalent because sharing of electrons makes relatively weaker bonds.

Explanation:

Ionic bonds: Type of chemical bonds in which transfer of electrons from less electro-negative atom to highly electro-negative atom occurs and with higher value of bond energy.

Covalent bonds: Type of a chemical bond in which sharing of an electrons between the two atoms occurs. Here electro-negativity difference between the atom is very less or zero. Lower value of the bond energy than that of the ionic bonds.

Bond energy of compound A is 769 kJ/mol higher than the bond energy of the compound B that is 432 kJ/mol which means that compound A is ionic  and compound B is covalent.

So, compound B is covalent because sharing of electrons makes relatively weaker bonds.

compound b is covalent because of sharing of electrons makes relatively weaker bonds.

the answer is na (sodium)
