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?

How many electrons are in the outermost energy level of carbon and how many does it need to have this energy level filled?
Carbon has four electrons in the outermost energy level, which is energy level two. It needs eight electrons to have this energy level filled.
What group on the periodic table does not form bonds?
With enough activation energy any group can form bonds but the group that needs the most activation energy is the noble gases.
Why sodium has valency 1 and chlorine also 1?
Sodium has a valence of +1, because it has 1 valence electron, which it will readily lose to form compounds with non-metals. Chlorine has a valence of -1, because it needs 1 electron to fill its outer electron energy level (it already has 7). Like sodium, it is easy for chlorine to do this, since it only needs one. In fact, sodium and chlorine easily react with each other to from sodium chloride, or salt.
Number of valence electrons in sodium?
Only 1, It's has 3 Energy Levels and only one Electron in it's outermost level.Sodium has 1 Valence Electrons. remember that in each group 1,2, 13, 14, 15, 16, 17, and 18 every element has the same Valence electrons in each group. Like Group 1 they all have 1 valence electrons. Group 2 has 2, Group 13 has 3, Group 14 all have 4, Group 15 all have 5, Group 16 all have 6, Group 17 all have 7, and finally Group 18 all have 8 valence electrons. the other groups have zero Valence electrons. Got to Touchspin on google and theres a periodic table that has the valence electrons for everything. On the side of the webpage its the second button that has the table.sodium has 8 valence electrons hint. the number of valence electrons is equal to the group number the element is in1,2, or 7 im not sureEdit: the answer is 1 electron in the valence shell, with a valence of 7Just like the rest of the alkali metals, sodium has one valence electron. This is why sodium is so reactive and has a low ionization energy--it is "eager" to get rid of this valence electron to fulfill the octet rule.See links/related questions below.Sodium has 1 valence election, just like all it's friends in the 1A group. Hope this helps!
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.
What group in the periodic tables needs the least energy to lose one electron?

How many electrons does group 7A need to become stable?
In the modern periodic table, these elements belong to group 17. These elements have s2 p5 electron configuration. Hence they need one more electron from an electron donor to fulfill its valence shell to obtain noble gas configuration.The elements in the group 7A has 7 electrons in their outermost energy level. They gain 1 electron to get the noble gas configuration. The elements in the group 7A are called halogens.
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 has four electrons in the outermost energy level, which is energy level two. It needs eight electrons to have this energy level filled.
A dog chasing a rabbit needs energy from the food it has eaten which process makes the usable energy for the dog?
the electron transport chain
What are the difference between direct and indirect band gap materials?
In a direct band gap the electron only needs energy to jump to the conduction band. In an indirect band an electron needs energy and momentum to jump to the conduction band
