Why do bonds form in terms of electrons

Atoms form chemical bonds to make their outer electron shells more stable. ... An ionic bond, where one atom donates an electron to another, forms when one atom becomes stable by losing its outer electrons and the other atoms become stable (by filling its valence shell) by gaining the electrons.

Explanation:

it should be all of them because it asks if you included all of those in your answer

explanation:

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.
