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 stands for selenium on the Periodic Table.
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.

Which elements have similar properties to sulfur?
Selenium and tellurium are elements that have similar chemical properties to sulfur. They belong to the same group (Group 16) in the periodic table, known as the chalcogens, and share similar chemical reactivity and properties with sulfur.
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.
