Three. The fourth shell would contain two out of a possible eight electrons.
A neutral atom of calcium has 20 electrons. Electrons fill the electron shells in order of increasing energy levels, with the first shell holding a maximum of 2 electrons, the second shell holding a maximum of 8 electrons, the third shell holding a maximum of 18 electrons, and the fourth shell holding the remaining 2 electrons. Thus, three electron shells (the first three shells) would be completely filled by a neutral atom of calcium.
A neutral xenon atom has 8 electron shells with 6 completely filled shells and 2 partially filled shells.
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.
A neutral xenon atom has 54 electrons. The electron configuration of xenon is [Kr] 4d^10 5s^2 5p^6, with a total of 8 completely filled electron shells (2 in the first shell, 8 in the second shell, 18 in the third shell, 18 in the fourth shell, and 8 in the fifth shell).
No. Xenon is a neutral element. It has completely filled valence orbitals, hence is stable. It does not form anion.

Carbon needs to have 8 electron in its outermost shell to have it completely filled, 4 more valence electrons than it has in the neutral for of carbon.
A neutral xenon atom would have 54 electrons filled in its electron shells.
completely filled valence shells
Neutral calcium has 20 protons and 20 electrons. The first 20 atomic orbitals are filled as 1s2 2s2 2p6 3s2 3p6 4s2. The shorthand for this is [Ar] 4s2 since argon's configuration is 1s2 2s2 2p6 3s2 3p6.
The first 3 energy levels are filled, the 4s and 4p and 4d sublevels are filled, and the 5s and 5p sublevels are also filled. So only the first three energy levels are completely filled. The fourth and fifth energy levels are partly filled. The electron configuration is 1s22s22p63s23p63d104s24p64d105s25p6 or [Kr]4d105s25p6.
a happy atom is an atom with all its electron shells completely filled
Xenon has five electron shells.
