How many electrons is needed to gain or lose to fill the outer shell?

It depends what element for example, lithium would need to gain 7 electrons or lose 1 so that the outer-most shell is full. However, elements like neon (which is a noble gas) don't need to gain or lose any electrons since the outer shell is already filled. It depends on it's place in the Periodic Table of the elements.

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.
How many valence electrons are needed to achieve a full outer shell?
It depends, most atoms need 8 total valence electrons in their outer shell (some need 2). So subtract the number they have (determined by the group that the element is in) from 8 and that is how many they need to fill their outer shell!
How many electrons does oxygen need to fill its outer shell?
10 electrons
How many electrons does Magnesium have in its outer most shell?
Magnesium has a total of 12 electrons. The electron configuration would be 1s2 2s2 2p6 3s2. Therefore, 2 electrons in it's outer shell.
Elements in the same group have similar properties because they have the same?
the same number of electrons needed to fill their octet, the same number of valence electrons,
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 would be needed to fill its outer shell for carbon?
4 to fill the 2p shell
How many electrons are needed to fill up carbons outer shell?
4 to fill the 2p shell
A total of how many electrons are needed to fill the outer shell of most atoms?
There is a total of 8 electrons that are needed to fill outer shell of most atoms. An atom is the smallest unit of matter.
How many electrons are needed to fill the outer shell of an atom?
8
How many electrons are needed to fill the outer shell of most atoms?
8
How many electrons does nitrogen need to fill its outer shell?
One electron is needed.
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.
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).
If carbon has four electrons in its outer shell does it completely fill its outer selectron shell?
Yes. Two of the electrons will go into the carbon's outer s shell (2s) to completely fill it (s orbitals can contain up to two electrons) and the remaining two will go into its outer p shell (2p).
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 are needed to achieve a full outer shell?
It depends, most atoms need 8 total valence electrons in their outer shell (some need 2). So subtract the number they have (determined by the group that the element is in) from 8 and that is how many they need to fill their outer shell!
