No. The inner shells are filled first.
Selenium has 5 filled electron shells. The electron configuration for selenium is 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p4.
completely filled valence shells
The electron configuration of sodium is 1s2 2s2 2p6 3s1. It has three principal energy levels. It has only one valence electron.
Neon is an element with all its electron shells filled it is a noble gas.
Sodium, i believe has 3 shells.
No. The inner shells are filled first.
Sodium has 3 energy levels, 1s, 2s, 2p, and 3s.
The correct number of electron clouds or shells sodium has is 3.
A neutral xenon atom has 8 electron shells with 6 completely filled shells and 2 partially filled shells.
Selenium has 5 filled electron shells. The electron configuration for selenium is 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p4.
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.
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.
completely filled valence shells
i dont think so
Sodium has 3 electron shells. The first shell can hold up to 2 electrons, while the second and third shells can hold up to 8 electrons each. Sodium has 11 electrons in total.
The electron configuration of sodium is 1s2 2s2 2p6 3s1. It has three principal energy levels. It has only one valence electron.
