How are covalent bonds created
WebThe remaining pairs of dots are called lone pairs, and the lines represent covalent bonds, or shared pairs of electrons. Because all three lines are located between the same pair … Web18 de abr. de 2016 · In a covalent bond, there is a presence of a partial charge in the atoms that combine to form a compound. For example in H X 2 O, since O is more electronegative, therefore there is a presence of a partial negative charge around O. Similarly, as H is less electronegative, it has a presence of a partial positive charge …
