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.

Mission MAM2 Orbitals

Mission MAM2 pertains to atomic orbitals. Students must understand the types of atomic orbitals - their basic shape, the number per energy level, and their electron capacity. The mission consists of 34 questions organized into 9 Question Groups.

Learning Outcomes

  • The student should be able to identify the different types of orbitals (s, p, d, and f) - their shape, notation (e.g., 2s, 4p), and electron capacity.
  • The student should be able to identify the type of orbitals and the number of orbitals of each type for the various energy levels (or n values).
