The group that needs one more electron to fill its outer energy level is the group of elements located on the right side of the Periodic Table known as Group 17, or the Halogens. These elements have seven valence electrons and are just one electron short of a full outer energy level.

In the electron cloud model if you begin at the electron shell closest to the nucleus of an atom and move out what is the number of electrons that each energy level or electron shell needs to fil?
The number of electrons that each energy level or electron shell can hold is given by the formula 2n^2, where n is the principal quantum number of that energy level. For example, the first energy level (n=1) can hold up to 2 electrons, the second energy level (n=2) can hold up to 8 electrons, and so on.
How many electron are needed to fill the outer energy level of sulfur?
Sulfur has 6 electrons in its outer energy level. This means it needs 2 more electrons to fill its outer energy level, for a total of 8 electrons.
How many electrons are in the outermost energy level of carbon and how many does it need to have this energy level filled?
Carbon's outermost energy level contains 4 electrons, and it needs 4 more electrons to have this energy level filled (total of 8 electrons).
Why does lithium bond?
Lithium bonds due to its tendency to lose an electron and achieve a stable electron configuration. By losing this electron, lithium can attain a full outer energy level, making it more stable and forming bonds with other elements to satisfy its electron needs.
When one electron moves from the 4th shell to the 2nd shell in hydrogen is energy absorbed or emitted by the atom?
Energy is emitted by the atom when an electron moves from a higher energy level to a lower energy level. This is known as an energy transition where the electron releases energy in the form of a photon as it moves closer to the nucleus.
How many electrons are in the outermost level of carbon how many electron does it need to have fill this energy level?
Carbon has four electrons in the outermost energy level, which is energy level two. It needs eight electrons to have this energy level filled.
Which family needs a electron to complete there outer energy level?
The Halogens F, Cl, Br, I, At

How many electrons does group 7A need to become stable?
Group 7A elements, also known as the halogens, need to gain one electron to achieve a stable electron configuration, typically by gaining an electron to achieve a full outer energy level of eight electrons (octet).
What group in the periodic tables needs the least energy to lose one electron?
Group 1 elements, commonly known as alkali metals, need the least energy to lose one electron because they have only one electron in their outermost shell. This electron is loosely held due to the shielding effect of inner electrons, making it relatively easy for these elements to lose it.
How many electrons does Sodium need to fill it's outer energy level?
It needs to lose one electron so that it can have 8 electrons in its outer orbital
How many electrons are in the outermost energy level of carbon and how many does it need to have this energy level filled?
Carbon's outermost energy level contains 4 electrons, and it needs 4 more electrons to have this energy level filled (total of 8 electrons).

In chlorine the outer energy level contains 7 electrons To attain stable state the chlorine atom needs to gain how many electrons?
To attain a stable octet configuration, chlorine needs to gain one electron to complete its outer energy level, reaching a total of 8 electrons.
How many electrons do hydrogen and helium need to fill their outermost energy level?
Helium already has a full valence shell. Because the first orbital holds two, and the second orbital holds eight...Helium is already filling the first shell with its two electrons, and it has no more electrons to spill into the second orbital, therefore it's one and only shell is full. Hydrogen tends to gain one electron in order to fill its outermost energy level. Hydrogen only has one, but it needs two to fill it's valence shell, so it will gain one. Long story short, helium is already full (that's why it's in the noble gas group) and hydrogen tends to gain one electron, and form a negative ion. No honey it has a number and that is 2 duh!!
