Compare what happens to the Atomic Radius as you add electrons to the orbital,
to when you add orbital/shells energy levels to an
atom.

explanation:

yes the other ones are right just show me a pic of ur face cuz u look hot

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.
