Compare the number of valence electrons on oxygen atom has with number of valence electrons a selenium atom has Are oxygen and selenium in the same period or group?
Oxygen has 6 valence electrons, while selenium has 6 valence electrons as well. Both oxygen and selenium are in the same group, Group 16 (also known as Group VIA or Group 6) of the periodic table. They are not in the same period – oxygen is in period 2, while selenium is in period 4.
What elements are in the same group as sulphur?
carbon, nitrogen, oxygen, sulfur,selenium, and phosphorus are all in the same group
Are oxygen and selenium in the same group?
yes
What fourth period representative element has similar properties to oxygen?
Sulfur is a fourth period representative element that has similar properties to oxygen. Both elements belong to group 16 of the periodic table, also known as the oxygen group, and have similar chemical reactivity.
Which elements are in the same group on the periodic table as oxygen?
sulfur, selenium, tellurium, and polonium
Which elements are in the same group as oxygen?
Elements in the same group as oxygen are sulfur, selenium, tellurium, and polonium. Group 16 elements are also known as the chalcogens and share similar chemical properties.
Locate the sulfurselenium and tellurium in the periodic table what group do they belong and what other elements belongs to the group?
Those elements are chalcogens, and the most significant other member of the group is oxygen. Polonium is also in the group, but from a chemical standpoint you can pretty much ignore it; it has no stable isotopes and exists only in trace amounts in nature (it's in the uranium-238 decay chain).
Is Selenium a transition metal?
No, Selenium is not a transition metal. It is a nonmetal element found in the oxygen group of the periodic table. Transition metals are characterized by their ability to form multiple oxidation states, which Selenium does not exhibit.
What is the nonmetal in period 4 that is more reactive than selenium?
The nonmetal in period 4 that is more reactive than selenium is sulfur. Sulfur is located above selenium in the same group (group 16) on the periodic table, making it more reactive due to its higher electronegativity and tendency to gain electrons in chemical reactions.
What atoms shows very similar properties to oxygen?
Elements showing properties similar to oxygen would be those that are found in the same group as oxygen (group 6A, or 16). Those would be sulfur (S), and selenium (Se)
What elements are in the same family as sulfur?
Sulfur is in the 16th group/family on the Periodic Table which is called Chalcogen.
How is selenium similar to sulfur?
Selenium and sulfur are both elements in the same group on the periodic table and share similar chemical properties. They can both form compounds with similar structures, and both have important roles in biological systems. However, selenium is less abundant in nature compared to sulfur.
