How many number of electrons to fill the outer shell of carbon?
Carbon has four valence electrons, so it will need four more electrons to fill its outer shell.
How many valence electrons do the insert gases have?
Enough to fill the outer-most shell. For most this is eight, but for helium it is two.
How many electrons are needed to fill up carbons outer shell?
Carbon needs 4 electrons to fill up its outer shell. It has 4 valence electrons and can achieve a full octet by gaining 4 more electrons.
How many valence electrons will beryllium gain or lose to fill its outer shell?
Beryllium will lose 2 electrons to satisfy the octet rule (to fill its outer shell).
Two electrons in helium are placed in only one shell while three electrons in lithium occupy two shells?
It is because the two electrons in helium are placed in K-shell. The K-shell has the capacity of only two electrons. Therefore, in Lithium the third electron is placed in the L-shell. You can find the capacity of a shell to hold electrons by the formula 2n2 where n is the shell no.
Does helium have a complete outer shell?
Not by itself, no (that is, hydrogen is not a noble gas). A neutral hydrogen atom starts out with 1 electron, but it needs 2 electrons to fill its shell. Therefore, a hydrogen atom will often form 1 covalent bond with another atom, in order to gain that 1 extra electron it needs to fill its shell. Important note: Most elements need 8 electrons to get a full shell, but hydrogen is the exception: it only needs 2 electrons to get a full shell.
What is the number of electrons to fill outer shell of sulfur?
Sulfur has 6 electrons in its outer shell. Therefore, it needs 2 more electrons to fill its outer shell.

How many electrons are needed to fill carbon outer shell?
Carbon has four valence electrons, so it will need four more electrons to fill its outer shell.
How many electrons does nitrogen need to fill its outer shell?
Nitrogen needs 3 more electrons to fill its outer shell. It has 5 electrons in its outer shell, and it typically needs a total of 8 electrons to achieve a full outer shell (octet rule).
What two atoms will have their outer energy level filled with two electrons?
Helium and neon will have their outer energy level filled with two electrons. Helium has 2 electrons in its only energy level, while neon has 8 electrons in its second energy level.
How many electrons are needed to fill up carbons outer shell?
Carbon needs 4 electrons to fill up its outer shell. It has 4 valence electrons and can achieve a full octet by gaining 4 more electrons.
How many valence electrons will beryllium gain or lose to fill its outer shell?
Beryllium will lose 2 electrons to satisfy the octet rule (to fill its outer shell).
How many electrons does nitrogen require to fill its outer shell?
Its atomic number is 7, and so it needs a further 3 electrons to fill its outer shell.
Two electrons in helium are placed in only one shell while three electrons in lithium occupy two shells?
It is because the two electrons in helium are placed in K-shell. The K-shell has the capacity of only two electrons. Therefore, in Lithium the third electron is placed in the L-shell. You can find the capacity of a shell to hold electrons by the formula 2n2 where n is the shell no.
Why helium does not form compounds?
Helium does not form compounds because it is a noble gas with a full outer electron shell, making it very stable and unreactive. Its outer shell is already filled with electrons, so it does not need to gain, lose, or share electrons with other atoms to achieve stability.
