Selenium is not a common element but is necessary.
strontium is not essential for living organisms. Sulfur is essential because all living things need it to survive. They also need sodium and selenium.
Selenium is indeed a chemical, and more specifically, it is a chemical element. It can be found on the periodic table of the elements.
No, selenium is a chemical element found on the periodic table with the atomic number 34 and symbol Se. It is a non-metal element that can exist in various forms, such as pure elemental selenium or in compounds with other elements.
The most common elements found in organic compounds are carbon, hydrogen, and oxygen. In living systems, the most abundant elements are carbon, hydrogen, oxygen, nitrogen, phosphorus, and sulfur.
The most common Selenium ion is Se2- the selenide ion. It is in the same group as oxygen and its most common ion in the oxide ion O2-.
Carbon
Remember the acronym CHNOPS: carbon, hydrogen, nitrogen, oxygen, phosphorus, and sulfur. These are the most common elements found in living organisms.
Common elements found in organic compounds include carbon, hydrogen, oxygen, nitrogen, phosphorus, and sulfur. These elements form the building blocks of organic molecules and are essential for the structure and function of living organisms.
Oxygen, Sulphur, Selenium, Tellurium, Polonium, and Livermorium. Have similar chemical properties as they are all in Group VIA (16). However, the last two are radio-active and not found in the open lab.

No, selenium is not a rare earth element. It is a nonmetallic element that is commonly found in the earth's crust and is used in various industrial applications. Rare earth elements are a group of 17 elements that are found in limited quantities and have unique properties.
