Are ionic bonds more powerful or colvant? and why do molecular compounds not have crystal lattice?

Ionic bonds are more powerful than covalant bonds

Explanation:

This is because of their strong lattice structure formed by the attraction between metals and non-merals.

Molecules donot exhibit crystal lattices because of the covslent bonds present in between their molecules

out of these options:

ability to burn paper

pure sodium reacting violently with water

the boiling point of water

helium does not tend to react with anything

i would say this is a physical property:

helium does not tend to react with anything

why? :

i said helium does not tend to react with anything because well, it reacts to ! but ability to burn paper, pure sodium reacting violently with water, & the boiling point of water are chemical or

physical properties: the properties of a substance that can be observed without changing the chemical makeup of the substance

chemical properties: properties of a substance relating to the chemical nature and reactivity of the substance
