Hydrogen fluoride has a Polar-covalent bond although, while the difference in electronegativity is more than 1.7 (we expected to be Ionic).t is covalent as there is not enough of a difference in electronegativity for the fluorine to completely pull the electrons away from hydrogen.
You need a permit to put up a fence. You need a permit for just about every damn thing you do in New Jersey. Some towns require permits for installing dishwashers and hot water heaters. I generally ignore them unless it's visible, but a fence definitely is.
Make sure the fence is not climbable. There should be no footholds or handholds or any areas large enough for a small child to get a foot or hand in.
