Went there are 8 is full
To determine how many more elections are needed to fill the outermost energy level of an atom, you need to know the number of electrons already present in that level and the maximum capacity of that level. The outermost energy level can hold a maximum of 8 electrons (following the octet rule) for main group elements. Subtract the number of existing electrons from 8 to find out how many more are needed to fill the level. For example, if there are 5 electrons in the outermost level, 3 more are needed to fill it.
In order for it to be a cation, the maximum number of electrons it can have is one less than the number of protons. I don't know what "needed" means in this context, but hopefully that answers what you were trying to ask.
Atoms in a covalent bond don't "know" which atom they belong to in the traditional sense. Covalent bonds form when atoms share electrons to achieve a full outer electron shell. The sharing of electrons creates a stable arrangement, but the atoms involved still maintain their individual identities.
Noble gases or the inert gases as they are become know as have a full outer shell. It is possible to get different elements to fill in the last outer shell but it is extremely difficult to take electrons from a noble gas therefore when you ask what the difference is the question is perhaps not phrased properly because there is no difference they are two different categories. A noble gas is an element with a full outer shell and full outer shell is when an element has filled all of the max electrons in the last orbital.
An atom contain protons, neutrons and electrons.

I don't know, will you answer this question, please, i need to know, the truth about this because i need it! Your Answer:
A carbon atom has four electrons in it's outermost energy level. Most atoms become stable when their outermost energy level contains eight electrons. A carbon atom therefore readily forms four covalent bonds with the atoms of other elements.
The number of unpaired electrons in valence shell or numbers of electrons less then 8 in outermost shell of an atom give information about covalent bonds my be formed by an atom.
in the outermost energy level . its alwys like that btw... did u know that i have toe fungus with little green things...i tasted it and then spit it out cause it was nasty. unfortunately, it landed in my brothers brocolli soup... just don't tell him that p.s pigs CAN fly ok, whoever wrote that, THATS DISGUSTING!!!! eww!!
If you mean "where are the valence electrons" then they are flying around the outside of the atom.If you mean "why" then I don't know. they're just there to be the outermost set of electrons.
The number of electrons in an atom's outermost shell determines its chemical reactivity, as atoms tend to seek a stable configuration with a full outer shell. Understanding this helps predict how atoms will bond with other atoms to achieve a full outer shell through sharing, gaining, or losing electrons. This knowledge is foundational in understanding the formation of chemical bonds.
Given what we know about electron structure, we would expect there to be 8 electrons in the outer shell of an atom with the atomic number of 10. And that's how many there are. Element 10 is neon, and like all noble or inert gases, it has a full outer shell.There are only two electron shells for all the elements up through element 10 (neon). The first shell will only accept 2 electrons. That's the s shell, and it's the outer shell (and the only shell) for helium (the lightest inert gas). The next 8 electrons will fill the second electron shell, which is the p shell. That means element 10 (the inert gas neon) will have a full s shell (2 electrons) and a full p shell (8 electrons).
Valence electrons are the electrons in the outermost energy level of an atom that participate in chemical bonding. These electrons are involved in forming bonds with other atoms to achieve a stable configuration. The number of valence electrons can determine an element's reactivity and the types of bonds it can form with other elements.
Electron arrangement makes it easy to know the number of electrons in the outermost energy level of atoms. Carbon, hydrogen, fluorine, argon, sulfur and magnesium have 4, 1, 7, 8, 6 and 2 electrons in their outermost energy levels respectively.
During emission, an electron in an atom transitions from a higher energy level to a lower energy level, releasing a photon in the process. In absorption, an electron absorbs a photon and transitions from a lower energy level to a higher energy level within the atom.
