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.

Name That Element - Questions 6 Help

The 100+ existing elements are organized into a table known as the Periodic Table. The familiar looking design of the table conveys information about a number of patterns in the behavior and properties of the elements. One of those properties is the property of mass. There is a general trend (that is broken on only a couple occasions) that the atomic mass of an element is seen to increase as one progresses across a row and down a column. Another pattern is that elements tend to act like metals or like nonmetals. The location of the nonmetals are in the upper right region of the table. Most of the elements are metals and can be found in the first 13 columns (known as groups) and a bit beyond. There are at least six elements that are difficulty to group with metals or with nonmetals because they tend to have properties of each. We refer to these elements as metalloids. Their location on the table reflects this idea, as they are located between metals and nonmetals along a zig-zag line that starts in Group 13 between Period 2 and Period 3 (periods are rows) and continues to the bottom of the chart. Learn more about metalloids in the How to Think About This Situation section below.

There are two similar questions in this Question Group. Each time one of the versions appears, the answer options are presented in a scrambled order. One of the two questions is shown below.
 

Version 1:
I am the least massive metalloid of period 4. Who am I?
Antimony (Sb)
Arsenic (As)
Gallium (Ga)
Germanium (Ge)
Scandium (Sc)
Selenium (Se)
Tin (Sn)
Yttrium (Y)

Much of what you need to know to answer this question is discussed in the Fundamentals section above. But if you would like to further your understanding, inspect and study the infographic below on the topic.
