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.
Of course, as long as the color, print, and texture of your tie, shirt and blazer match. For example you don't want to wear a silk shantung or satin silk bow tie with a felted wool blazer or cord button down shirt. The weight and texture of each and every pieces should compliment each other. Mixing print is tricky.
