Answer:
2nd option is the correct answer of this question
Answer:
Solid ionic compounds do not conduct electricity because the ions are held firmly in place. The ions cannot move to conduct the electric current. But when an ionic compound melts, the charged ions are free to move. Therefore, molten ionic compounds do conduct electricity.
Answer:
Their valence electrons/properties
Explanation:
Elements in the same group of the periodic table have the same amount of valence electrons, which determines how they bond with other elements in other groups. This also determines their properties such as their reactivity. Since Li, Na, and K are in the same group, they must have similar properties and the same amount of electrons in their outermost shell.
The amount of kinetic energy required for the molecules to break free of the intermolecular forced in the liquid is raised because the other ones don’t make sense
