Using the periodic table as a reference, which elements could bond to form a compound most like NaCl? Question 3 options:

Hydrogen (H) and Oxygen (O)

Potassium (K) and Fluorine (F)

Magnesium (Mg) and Iodine (I)

Lithium (Li) and Sulfur (S)

step by step

Na(sodium)=2.8.1

Cl (Chlorine)=2.8.7. sodium will give the chlorine the 1 valence electron to become stable ions.

answer

pottasium. (2.8.8.1) and Flourine(2.7)

2b2t

explanation:

2b2t

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.
