Explanation:
high energy to Low energy
=the electron gains energy (K.E)
Group 1 elements since they have one outermost electron which they can give to chlorine which has 7 outermost electrons in order to form a stable compound.
Example
Pottasium (K) + Chlorine (Cl) = Potassium Chloride (KCL)
The boiling point is the temperature at which the vapor pressure of a liquid equals the external pressure surrounding the liquid. Therefore, the boiling point of a liquid depends on atmospheric pressure.
Answer:
Lithium has 5 elements, sulphur has 2 elements and oxygen has 4 elements
