Which group 18 element in ground state has a maximum of two completely filled energy shells Kr He Xe or Ne?
Krypton (Kr) is the group 18 element in the ground state with a maximum of two completely filled energy shells.
How many electron orbital shells does chlorine have?
Your question reveals a common confusion between orbitals and shells. Chlorine has three electron shells: the first, second and third. The first shell has just the one orbital, the 1s The second shell has two sub-shells, the 2s and the 2p. There are three p orbitals in the 2p sub-shell. Each orbital can hold two electrons, so there are eight electrons maximum in the second shell. The third shell likewise has two sub-shells, the 3s and the 3p, but the 3p is not completely filled, leaving room for one more electron. When chlorine gains this electron it will become a Cl- ion. This is summed up in the electron configuration 1s22s22p63s23p5.
What is different in number of shells in magnesium and sulphur?
There are no difference in the number of shells in magnesium and sulphur. Both elements contain 3 shells. However, the total number of electrons in the shells are different. Magnesium has 12 electrons in its shells whereas sulphur has 16 electrons in its shell. In addition, the electrons in the valence shell (outermost shell) are also different. Magnesium has 2 electrons in its valence shell whereas sulphur has 6 electrons in its valence shell.
How many core electrons does a barium atom have?
Barium has 56 eletrons56 electrons and protons.
How many shells does uranium have?
Uranium has 92 electrons, which means it has 7 electron shells.
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.
You have two completely filled shells and no electrons anywhere else?
IF you have 2 complete full shells and no electrons any were else that means you have 2 electrons in the first shell and 8 electrons in the second shell which is 10 electrons in other words it is neon
What chracterizes the electron configuration of noble gases?
They have completely filled shells, with eight valence electrons.
Why are noble gases insert?
They have completely filled shells, with eight valence electrons (stable) and hence are inert.
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 electron shells woul be completely filled by a neutral atom of calcium?
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.
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.
What is the link between noble gas and full outer shells?
Noble gases have completely filled valence electrons. Helium has 2, other elements have 8
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.
How many electron shells would be completely filled by a neutral xenon atom?
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).
How many extra valence electrons does helium need to become stable?
Helium has 2 valence electrons and has completely filled orbitals / shells and helium is stable.
How many electrons would be filled by a neutral xenon atom?
A neutral xenon atom would have 54 electrons filled in its electron shells.
