umm, its 4. Periods are horizontal lines on the Periodic Table of elements.
What else can I help you with?
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.
Where is selenium located in the periodic table?
Selenium is located in Group 16, Period 4 of the periodic table. It is a nonmetal element with the symbol Se and atomic number 34.
In what group is selenium in the periodic table?
Selenium (Se) is in oxygen family (group 16 or VIA) and in 4th period.
In what group and period cerium belong?
It is a lanthanide in period 6.
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.
Are oxygen and selenium in the same period or the same group?
They are in the same group and they are not in the same period.
Do helium and selenium have any similarities?
No. they belong to different groups and hence have different properties

What is the family and group for selenium?
period 4 oxygen family or chalcogens
Which elements are in the same periodic table as oxygen?
sulphur, selenium, tellurium and polonium belong to the oxygen family.
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.
What period does scandium belong to?
Period 4
What period does haydn belong to?
Classical period
What elements belong to the oxygen group?
Sulphur, selenium, tellurium, polonium and Uuh are other members of oxygen family.
Where is selenium located in the periodic table?
Selenium is located in Group 16, Period 4 of the periodic table. It is a nonmetal element with the symbol Se and atomic number 34.
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 family and period does niobium belong?
niobium period
