Generally the higher the energy level, the farther away the orbital is from the nucleus.
Electrons don't really work like that, and even if they did, there's no theoretical limit on the number of "shells" (which aren't really shells).

What did Rutherford proposed?
He proposed a new model of the atom in which there is a small dense positively charged nucleus with negatively charged electrons around the outside. The electrons are far away in comparison to the size of nucleus, so the majority of the atom is made up of empty space.
How big is the nucleus compared to the atom as a whole?
Not very big. The nucleus of an atom, the part containing protons and neutrons (1H, protium, consists of only a proton and an electron) takes up only a tiny portion of the atom's volume. The volume of an atom is really described by the movement of the electrons that orbit about the nucleus. Those electrons are a looooong way from the proton(s) relative to their size. A nucleus is about 10 FM in diameter. In a solid, nuclei are 1000000 or more FM apart. Hydrogen is small compared to other atoms. To scale it up: if the proton in its nucleus was enlarged to the size of a basketball, the electron would be some 20 miles away or so. With other atoms, the picture gets more crazy. The reality is that an atom is mostly space, and you've probably heard that. The nucleus of an atom is super tiny compared to the 95% boundary described by the outer electrons of an atom. The boundary can't be well-defined, really, because of what quantum mechanics, the uncertainty principle, and Schroedinger's wave equation have to say.
Why do the atoms in the top rows in the periodic table have higher electronegativity than atoms from lower rows?
its to do with the groups not the atoms the group at the bottom of the table are rare earth metal (58-103) and these are just the way Mendeveel (the person who made the pt) set them out i am not sure why. Just physics and chemistry nothing else. jddfm I wouldn't agree with the above statement. I would say that the atomic radii of an atom increases going down a group because as we move down the periodic table each atom has more electron shells and so the valence electrons end up further away from the nucleus which in turn means the electrostatic force between the nucleus and the valence electrons decreases and the atom is "larger".
When objects become charged it is electrons that are transferred from one object to another rather than protrons?
1) Electrons are only a thousands of the mass of protons.2) Electrons are held to an atom by electromagnetic forces,the protons are held by the strong force ... which is much more powerful.
What keeps an electron in motion around the nucleus to which it is attracted?
Actually, its more of a matter of why don't they fall into the nucleus and stop moving. You see, electrons are very chaotic particles that always move around because of the kinetic energy (kinetic energy is the energy of a moving object) they carry, and at a subatomic scale it is very difficult, and practically impossible, to "stop" a particle i.e. reduce its kinetic energy to zero. So you see, when electrons are bound by electrostatic forces to atomic nuclei, they can't fly away because of the attraction between the protons of the nucleus and them, but they also can't just stick to said nuclei because they still have kinetic energy which keeps them moving.A simple analogy is spinning a string with a small stone tied to the opposing end. The stone spins around the opposite end of the string because it is bound to that point by the string, but it can't fall towards it because it has a lot of kinetic energy that's trying to make it fly away.Hope this was useful.
Which electrons are the valence electrons of an atom?
The electrons farthest away from the nucleus are the valence electrons of an atom.
Which electron are the valence electrons of the atom?
The correct answer is: The electrons farthest away from the nucleus... chris ellis
What is the energy level farthest away from the nucleus of the atom that holds 8 or more valence electrons?
The valence electrons of an atom are those electrons that are in its outer energy shell or that are available for bonding. The electrons more loosely held by the nucleus - are the ones that are gained, lost or shared.
Which electrons are the valence electrons of the atom?
Valence electrons are the electrons in the outermost energy level of an atom. These are the electrons involved in forming chemical bonds with other atoms to create molecules and compounds.
Which electrons are the valence electrons of the atoms?
The correct answer is: The electrons farthest away from the nucleus... chris ellis
Is the outermost electron shell the highest or the lowest energy level shell?
No, the farthest electrons are at the highest energy level.No, the farthest electrons are at the highest energy level.No, the farthest electrons are at the highest energy level.No, the farthest electrons are at the highest energy level.
Why does electrons move around the nucleus and not away from atom?
Electrons are negatively charge and are attracted to the positively charged Protons in the nucleus of the atom
What electrons of an element are responsible for reacting and bonding with other elements?
Valence electrons are responsible for reacting and bonding with other elements. These are the electrons in the outermost energy level of an atom and determine the atom's ability to form chemical bonds with other atoms.
Why are valence electrons easier to remove from an atom than core electrons?
Valence electrons are further away from the nucleus and experience less attraction to the positively charged protons in the nucleus compared to core electrons. This makes valence electrons easier to remove from an atom. Core electrons are located closer to the nucleus and are more strongly attracted to the nucleus, requiring more energy to remove them from the atom.
Why the size of atom is biggest than nucleus?
The size of an atom is bigger than the nucleus because an atom consists of a nucleus surrounded by electron clouds. The electrons are located further away from the nucleus, leading to the overall larger size of the atom.
The nucleus of an atom consists what part?
The nucleus of an atom consists of protons and neutrons. Protons are positively charged and neutrons are neutral. Electrons orbit around the nucleus.
Where does electron exist in an atom?
Electrons exist in the electron cloud that surrounds the nucleus of an atom. This cloud is made up of the various orbitals that hold the electrons. Orbitals are regions of space in which the probability of finding an electron is the highest. The electrons orbit the nucleus in these orbitals and can move from one orbital to another as they gain or lose energy. 1s Orbital: This orbital is closest to the nucleus and can hold up to two electrons. 2s Orbital: This orbital is farther away from the nucleus and can hold up to two electrons. 2p Orbitals: These orbitals are even farther away from the nucleus and can hold up to six electrons. 3s Orbital: This orbital is farthest away from the nucleus and can hold up to two electrons. 3p Orbitals: These orbitals are even farther away from the nucleus and can hold up to six electrons. 3d Orbitals: These orbitals are the farthest away from the nucleus and can hold up to ten electrons.These orbitals are filled in a specific order with the 1s orbital being filled first then the 2s 2p 3s 3p and finally the 3d orbitals. The electrons in the outermost orbitals are called valence electrons and are responsible for the chemical properties of the atom.
