Selenium has 5 filled electron shells. The electron configuration for selenium is 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p4.
How many electron shells would be completely filled by a neutral xenon atom how many would be left over?
A neutral xenon atom has 54 electrons. Two of its electron shells would be completely filled, with 2 and 8 electrons, leaving 44 electrons in the remaining electron shells.
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.
How many orbitals are completely filled in xenon?
Xenon has five electron shells.
How many electron shells would be completely filled by a neutral atom of calcium?
A neutral atom of calcium has 20 electrons arranged in the electron shells. The electron configuration for calcium is 2-8-8-2. The first two shells (K and L) are completely filled, while the M shell is partially filled with 2 electrons.
How many electrons are needed in hydrogen helium carbon and oxygen to fill their respective valence shells?
Hydrogen has one electron and needs one more. Helium has two electrons and has filled shell. Carbon needs four more electrons to fill the valence shell Oxygen needs two more electrons to fill the valence shell
