What else can I help you with?
Why are noble gases insert?
They have completely filled shells, with eight valence electrons (stable) and hence are inert.
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 extra valence electrons does helium need to become stable?
Helium has 2 valence electrons and has completely filled orbitals / shells and helium is stable.
What are stable electron configurations are likely to contain?
completely filled valence shells
Why are the noble gases unreative?
they have completely filled shells (or orbitals) and are hence stable and unreactive.
What Atom has 2 completely filled shells and no electrons anywhere else?
The atom that has 2 completely filled electron shells and no electrons anywhere else is helium. Helium has a total of 2 electrons, with both shells being completely filled with 2 electrons in the first shell.
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.
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.
