The atoms form positive and negative ions which attract to each other. Ionic compounds are composed of large numbers of positive ions (cations) and negative ions (anions) so that the amount of positive charge equals the negative charge. In covalent bonds the electrons are shared between two bonded atoms.
4. Try doing a gradation of color by selecting a shirt and tie that are the same color, but in lighter or darker shades. For example, pair a light blue dress shirt with a medium blue tie. 5. For business interviews and important meetings, keep your tie color classic and conservative.
Our recommendation is that your bow tie and shirt should be of two different colors. Wearing the same color twice in overlapping layers is quite useless in the case of bow tie-shirt combos. Of course, one easy way to go is to wear one of your pieces in a neutral color and the other one in a non-neutral color.
