How many shells are there in selenium atom?
Selenium has four electron shells.
What is the number of valence electrons in selenium?
Selenium has 6 electrons in its outermost shell.
Are the outer electron shells always filled first?
No. The inner shells are filled first.
How many orbitals are completely filled in xenon?
Xenon has five electron shells.
How many filled electron shells does helium have?
Helium has only 1 shell with two electrons.
How many shells are there in selenium atom?
Selenium has four electron shells.
What is the number of valence electrons in selenium?
Selenium has 6 electrons in its outermost shell.
How many electron shells would be completely filled by a neutral xenon atom how many would be left over?
5 shells filled, no electrons left over.
How many electron shells would be completely filled by a neutral xenon atom?
Three electron shells would be completely filled by a neutral xenon atom.
Are the outer electron shells always filled first?
No. The inner shells are filled first.
How many electron shells would be completely filled by a neutral xenon atom and how many would be left?
Five shells and none left over.
Are atoms most stable when they have partially filled shells?
no. they are more stable when they have completely filled or half filled shells
How many orbitals are completely filled in xenon?
Xenon has five electron shells.
How many filled electron shells does helium have?
Helium has only 1 shell with two electrons.
How many electron shells woul be completely filled by a neutral atom of calcium?
3 would be totally filled there would be two left in the fourth ring
How many electron shells will be filled by xenon?
The electronic configuration of xenon is 2, 8, 18, 18, 8. So there are FIVE electrons shells that are filled. Alternatively, xenon belongs to 5th group, so the fifth shell is the valence shell.
Why are noble gases are non reactive?
They have filled valence shells. Atoms undergo chemical bonding in order to have filled valence shells by sharing electrons or transferring electrons. Because the noble gases already have filled valence shells, they have no need to react with other elements.
