What else can I help you with?
What is the name given to the outer shell of the atom?
The outer shell of an atom is the valence shell, which contains the valence electrons.
What happens when the outer shell of an atom is not filled?
big boom!
An atom is chemically stable when it’s outer ____ is completely filled with?
Its outer shell is filled with electrons.
In which case is an atom least likely to bond with an atom?
If it's outermost electron shell is filled.
How many unpaired electrons are present in a neutral mercury atom?
There are no unpaired electrons in an unexcited neutral mercury atom; its outer shell contains only two s electrons that are paired, as are all the electrons in the filled inner shells of the atom.
An atom contains seven electrons in its outermost energy level the atom is what?
The question is somewhat vague. If the question were written as an atom contains seven electrons in the outermost energy level and that outermost shell is a p-shell then the atom is a halogen. If the atom contains seven electrons in the outermost energy level and that outermost shell is a d-shell or f-shell then the atom is a metal.
What is an atom that will lose or gain electrons until they have a full outer shell?
Anion (if it has an almost-filled outer shell) or a cation (if only the outer S orbital is filled or partially filled)
An atom that has 3 electrons in its second shell and a filled first shell will?
be stable because the first shell is filled with electrons, providing it with a stable configuration. The second shell having 3 electrons will also fulfill the octet rule, making the atom more stable.
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 electrons would be filled by a neutral xenon atom?
A neutral xenon atom would have 54 electrons filled in its electron shells.
Which atom contains eight electrons?
Oxygen. Two of the electrons are in the first shell. The other six of them are in the second shell.
In which is an atom least likely to bond with other atoms?
If it's outermost electron shell is filled.
