What is the number of valence electrons in selenium?
Selenium has 6 electrons in its outermost shell.
How many core electrons does selenium have?
Selenium is Atominc number: 34 It has 6 Valence electrons Therefore you take 6 from 34: 28 core electrons
How many valence electrons do the 6A elements have?
The Group 6A elements are oxygen, sulfur, selenium, tellurium and polonium. The number of valence electrons in Group 6A is 6.
Oxygen sulfur and selenium belong to group 16 on the periodic table What does this indicate?
They have the same number of valence electrons
What is the expected number of valence electrons for a group 3 A element?
The expected number of valence electrons for a group 3 A element is 5 number of valence electrons.
What is the number of valence electrons in selenium?
Selenium has 6 electrons in its outermost shell.
How is selenium similar to sulfur?
yes, an oxygen atom have the same number of valence electrons as a selenium atom.
Does selenium and bromine have the same number of valence electrons?
No, Selenium has 6 valence electrons while Bromine has 7. You can determine this because on the periodic table, Selenium is in Group VI while Bromine is in group VII.
Which of the following would not have the same number of valence electrons as the others boron aluminum gallium selenium?
Selenium
How many core electrons does selenium have?
Selenium is Atominc number: 34 It has 6 Valence electrons Therefore you take 6 from 34: 28 core electrons
Which has a different number of valence electrons oxygencarbonsulfurselenium?
Carbon is in group 14 and has 4 valence electrons, oxygen sulfur and selenium are in group 16 and have 6 .
How many electrons are in a selenium ion?
Selenium has 34 total electrons. It has 6 valence electrons.
How many valence electrons do the 6A elements have?
The Group 6A elements are oxygen, sulfur, selenium, tellurium and polonium. The number of valence electrons in Group 6A is 6.
Oxygen sulfur and selenium belong to group 16 on the periodic table What does this indicate?
They have the same number of valence electrons
Why is selenium found in group 6A of the p block?
Because it has same number of valence electrons in the same energy level.
How do you find number of valence electrons?
Take the atomic number then subtract the amount of valence electrons. Example: Number of non valence (inner) electrons in Sulfur: 16 (atomic number) - 6 (valence electrons) = 10 (valence or inner electrons)
What is the number of valence electrons for He?
Two valence electrons.
