Iodine is a nonmetal with a high electronegativity, Xenon is a noble gas with a complete outer shell of electrons making it stable, and Selenium is a metalloid with properties intermediate between metals and nonmetals. Their positions in the Periodic Table indicate their atomic structure and properties such as reactivity, electronegativity, and metallic behavior.

How did Mendeleev drcide where to place arsenic and selenium on the periodic table?
Mendeleev placed arsenic and selenium on the periodic table based on their chemical properties and atomic masses. He arranged elements by increasing atomic mass and grouped them by similar properties. By doing so, he could predict the properties of undiscovered elements and fill in gaps in the periodic table.
What elements with similar properties as selenium?
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.
What is the composition and structure of selenium?
Selenium is a nonmetal element that belongs to the oxygen group of the periodic table. Its atomic number is 34, and it has multiple allotropes with different physical and chemical properties. Selenium exists in various forms, including elemental selenium, selenide ions, selenite ions, and selenate ions.
What does se stand for on periodic table?
Se on the periodic table stands for selenium. Selenium is a nonmetal element with atomic number 34. It is commonly used in the electronics industry and is essential for human health in small amounts.
Is the element selenium a member of group 6A?
Yes, selenium is a member of Group 16, also known as Group 6A, in the periodic table. This group is known as the chalcogens, and selenium shares similar chemical properties with the other elements in this group like oxygen and sulfur.
What element has similar properties as sulfur?
Selenium has similar properties to sulfur as they are both in the same group on the periodic table (Group 16) and share similar chemical reactivity and properties.
What are the family members of the sulfur element?
The family members of sulfur in the periodic table are oxygen, selenium, tellurium, and polonium. These elements belong to the same group in the periodic table as sulfur and share similar chemical properties.
What does se stand for on periodic table?
Se on the periodic table stands for selenium. Selenium is a nonmetal element with atomic number 34. It is commonly used in the electronics industry and is essential for human health in small amounts.
Is selenium magnetic?
No, selenium is not magnetic. It is a non-magnetic element with no magnetic properties.
How did mendeleev place arsenic and selenium?
Mendeleev placed arsenic before selenium in his periodic table based on their atomic weights and chemical properties. Arsenic has a lower atomic weight and exhibits similar chemical behavior to other elements in its group, making it a better match for the position before selenium.
Why do selenium and sulfur have similar chemical properties in terms of electron configuration?
Selenium and sulfur have similar chemical properties because they are in the same group on the periodic table, known as the chalcogens. Both elements have similar outer electron configurations, with sulfur having 6 electrons in its outer shell and selenium having 6 as well. This similarity in electron configuration leads to comparable chemical behavior in terms of oxidation states and reactivity.
Slogans for periodic table element selenium?
Shining bright with selenium. Selenium: Powering up your health. Sparkle with selenium in your life. Selenium: Essential for your well-being.
Is selenium a metal or a non metal?
Nonmetal because Selenium is used to make light sensors so it cant melt at low temperatures and it conducts electricity at a low level like a lot of non - metalsSelenium is considered a nonmetal.
What element has similar properties to sulfur?
Selenium has similar properties to sulfur. Both elements are in the same group in the periodic table (group 16), known as the chalcogens, and they exhibit similar chemical behaviors.
Is selenium a chemical?
Selenium is indeed a chemical, and more specifically, it is a chemical element. It can be found on the periodic table of the elements.
Is selenium a metal?
Yes, selenium is a nonmetal element that belongs to the group of chalcogens in the periodic table. It is not a metal.
What are three elements that have similar chemical properties to oxgen?
Three elements that have similar chemical properties to oxygen are sulfur, selenium, and tellurium. These elements belong to the same group as oxygen in the periodic table and have similar electron configurations, which influence their reactivity and chemical behavior. Additionally, they can form similar types of chemical bonds with other elements.
