An alkali metal is most likely to form an ionic bond with an element from which group?
noble gases
halogens
alkaline earth metals
transition metals

the correct answer is B. Hallogens hope this helped mind helping out with making me brainliest?

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.
