In sodium (Na), which has an atomic number of 11, the electron configuration is 1s² 2s² 2p⁶ 3s¹. This means that the first shell (1s) is filled with 2 electrons, the second shell (2s and 2p) is filled with 8 electrons, and the third shell (3s) contains 1 electron. Electrons fill the shells starting from the lowest energy level (1s) and move to higher levels (2s, 2p, and then 3s) until all 11 electrons are accommodated. Sodium's single valence electron in the 3s shell makes it highly reactive, as it tends to lose that electron easily.
What else can I help you with?
Are the outer electron shells always filled first?
No. The inner shells are filled first.
How many filled shells in selenium?
Selenium has 5 filled electron shells. The electron configuration for selenium is 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p4.
What are stable electron configurations are likely to contain?
completely filled valence shells

How many orbitals are completely filled in xenon?
Xenon has five electron shells.
How many electron shells does Sodium have?
Sodium, i believe has 3 shells.
What is sodium's number of electron shells?
Sodium has 3 energy levels, 1s, 2s, 2p, and 3s.
Are the outer electron shells always filled first?
No. The inner shells are filled first.
How many shells can an electron cloud have?
The correct number of electron clouds or shells sodium has is 3.
How many electron shells would be completely filled by a neutral xenon atom and how many would be left?
A neutral xenon atom has 8 electron shells with 6 completely filled shells and 2 partially filled shells.
How many filled shells in selenium?
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.
What are stable electron configurations are likely to contain?
completely filled valence shells
