WebHydrogen bonding is a special type of dipole-dipole interaction that occurs between the lone pair of a highly electronegative atom (typically N, O, or F) and the hydrogen atom in a N–H, O–H, or F–H bond. WebIf a molecule has 4 hydrogens and 1 carbon (methane, as in the example above), and we know that electrons repel each other, then there's only one set of angles that allow those electrons to all be as far apart from one another as possible. The lower the number of electrons, the greater the angle, presumably. ( 31 votes) Show more... usbatlle

WebBecause of its 1s 1 electron configuration and the fact that the 1s orbital can accommodate no more than two electrons, hydrogen can (a) bond to other elements by losing an electron to form a proton, which can accept a pair of electrons from a more electronegative atom to form a polar covalent bond; (b) gain an electron from an electropositive … how far can lice travel off the head
