Physics Classroom is making strides to make our site accessible to everyone. Our site contains 6 navigation areas. The Primary, Secondary, and Page Level navigations have a screen reader version of their nav structure that allows using the left and right keys to navigate sibling navigation items, and up or down keys to navigate parent or child navigation items. The others can be navigated using tabs. The Primary Navigation handles the first 2 levels of site pages. The Secondary (which is not always available) handles the 3rd and 4th level of structure. The Page level navigation allows you to navigate the current page's headings quickly. The Header Navigation contains the Light/Dark Mode toggle, Search, Notifications and account login. The Breadcrumb Navigation contains the breadcrumb of the current page. If the current page has a breadcrumb, you can get to it by skipping to the content and tabbing in reverse (shift plus tab). The Footer Navigation contains links such as Privacy, Contact, about and terms. Some resources contain an Audio Player that can be activated by holding down the T key for 3 seconds, and then using K to pause and resume. While not every area of Physics Classroom is usable purely from keyboard and screen reader, we are committed to continue work on making this possible. If you have questions or need additional help, please use this link to contact us.

Home Concept Builders Chemical Bonding and Molecular Shape Bond Polarity Directions

Bond Polarity - Directions

Using the Bond Polarity Concept Builder is quite simple. There are three difficulty levels in all. All three levels work the same way. You must use electronegativity values for two elements to determine if the bond between them is non-polar or polar. If it is polar, then you will have to identify the direction of the dipole moment vector. When the Question is first presented, the bonded elements are identified and a Tap Me! button is displayed below the bonded elements. You can tap this button to toggle between the choices non-polar and polar. If you select polar, a second Tap Me! button appears that allows you to set the direction of the dipole moment vector. It is either directed towards the right-most element or towards the left-most element. Repeated tapping toggles the arrow back and forth between the two options. As long as you have fully answered the question, a Check Answer button will be visible. If satisfied with your answer, then tap on the button. Your answers will be evaluated, feedback will be given, and your Progress Report will be updated.

Your goal is to earn "Stars" and to complete one or more difficulty levels. Stars are earned when you show success on a particular question. Once you show success on all the questions for a particular level, you will earn the trophy for that level.
