The group 6A, also called group 16, elements are oxygen, sulfur, selenium, tellurium, polonium, and element 116. Each has six of the desired eight electrons required for the octet in its highest energy level. Each thread that executes the test plan is completely independent of other test threads. There are many methods which are used to determine the visibility scope for the web elements - isSelected(), isEnabled() and isDispalyed(). Table of Contents. The element selenium (symbol Se) is much rarer than oxygen or sulfur, comprising approximately 90 parts per billion of the crust of the Earth. A. OpenRecord B. Elemental selenium is relatively nontoxic and is considered to be an essential trace element. The. Solutions. It is a nonmetal with properties that are intermediate between those of its periodic table column-adjacent chalcogen elements sulfur and tellurium. It is often found in combination with metals like mercury, copper, silver or lead. The symbol of the selenium element is Se. All of these elements exhibit allotropy. Selenium is a non metallic chemical element exists in several allotropic forms, although three are generally recognized. I can easily get Selenium to produce a list of the contents of each top level element by doing: driver.find_elements_by_class_name('person') But then I can't iterate through the list because the above method doesn't narrow the scope/source to just the contents of that element. In group 16 there are two non-metals: Oxygen and Sulphur, Two metalloids: selenium and tellurium and two radioactive metals: polonium and livermorium. Selenium is rare, composing approximately 90 parts per billion of the crust of Earth.
