Why does sodium become stable by losing one electron?
Sodium has 1 valence electron in its outer shell. By losing this electron, sodium achieves a full outer shell, which is more stable. This stable configuration is achieved by following the octet rule, where atoms tend to gain, lose, or share electrons to have 8 electrons in their outer shell.
How many valence electrons will make an element happy or stable?
Most elements are stable with a full outer shell of electrons, typically with 8 electrons known as the octet rule. However, elements in the first shell can be stable with 2 electrons. This full outer shell results in a stable configuration similar to the noble gases, making the element happy or stable.
How can bromine gain a stable outer electron shell?
Bromine can gain a stable outer electron shell by accepting one electron to fill its 4p orbital, achieving a full valence shell of eight electrons. This allows it to have the electron configuration of a noble gas, like argon, and become a stable ion.
Why does carbon become stable after sharing four electrons?
Carbon becomes stable after sharing four electrons because it achieves a full outer shell of electrons, known as an octet. This full outer shell configuration is energetically favorable and increases the stability of the atom. By sharing electrons with other atoms to fill its outer shell, carbon can achieve this stable configuration.
Are atoms with eight electrons in the outer shell not reactive at all?
Atoms with eight electrons in their outer shell (a full valence shell) are considered stable and less likely to react with other atoms to form molecules. However, there are exceptions to this rule such as noble gases like helium, neon, and argon.
Is sodiums outer shell full?
Yes
Is sodiums outer shell complete?
No. It has one electron which is readily lost to produce the Na+ ion. Note - the ONLY elements with a complete outer shell are the noble gasses.
Does lithium have a full outer shell?
no it only has 1 electron in the outer shell
How many valence electrons are needed to fill sodiums outer shell?
Sodium has ONE valence electron in its outer shell that is to be donated to any kind of oxidant. By then the outer (3rd) shell (of the Na+ ion) is EMPTY, so the 2nd shell has become the outmost, containing 8 electrons (Ne-configuration). No electrons at all are taken up by sodium.
What makes an element stable?
an element is stable when it has a full outer shell of electrons. to abide by the octet rule it must have a shell of 2 then 8 electrons. An element with a full outer shell (8) will be stable and act like its nearest noble gas.
What are Atoms with a complete or closed outer shell?
a stable compound
What are the conditions for stable electric configuration?
The valence/outer shell has to be completely full to be completely stable.
An atom is chemically stable when it’s outer ____ is completely filled with?
Its outer shell is filled with electrons.
Why does sodium become stable by losing one electron?
Sodium has 1 valence electron in its outer shell. By losing this electron, sodium achieves a full outer shell, which is more stable. This stable configuration is achieved by following the octet rule, where atoms tend to gain, lose, or share electrons to have 8 electrons in their outer shell.
How many electrons does an atom need in its outer shell to be stable?
5
Does an atom need 8 electrons in its outer shell to be stable?
YES!
What are atoms with a complete or closed outer shell called?
Stable atoms.
