Because of the electromagnetic force. It requires more energy to pull a negatively charged electron further away from the positively charged nucleus.

∙ 12y ago- Cause if it were inside the nucleus it wouldn't be an orbit.
- the electron has to maintain a certain amount of energy to resist the eletro-static force of the opposite charge of the nucleus.
- The electron isn't exactly a particle but is a standing wave and posses the velocity of light only as a frequency component.

∙ 11y agoIn most atoms, there are more than one electron orbiting a given nucleus, and since the electrons repel each other (like charges repel) they cannot get too close to the nucleus without also getting too close to each other. If there is just one electron, in the case of the hydrogen atom, its energy content keeps it in orbit at a certain distance, much as the momentum of planets keep them at a certain distance from the sun. If the electron loses energy it can get closer to the nucleus, but then it will wind up falling in to the nucleus and reacting with the proton to form a neutron, at which point the hydrogen atom no longer exists.

What is the state of matter when electrons are stripped away from the nuclei?
This is plasma.
What causes electrons to flow through a conductor?
There are 1 to 3 electrons in outer orbit of a conductor witch the element wants to give away in order to have inner orbit complete at the cost of getting positive charge when forced by the electric voltage.If outer orbit have 4 electrons like carbon,silicon or germanium, it acts as a semiconductor. And if outer orbit have more than 5 electrons, it will resist electron flow.
How do you get the number of neutrons in a element?
To find the number of neutrons in an atom you would subtract the protons from the atomic mass. The number of protons is equal to the atomic number. When dealing with an element with no net charge, the atomic number = the number of protons and also the number of electrons. The atomic mass - the atomic number (number of protons and electrons) = the number of neutrons
Why can metals such as copper and silver become charged by induction while plastic materials cannot?
Metals have one or two( or at the most three as in case of aluminium ) free electrons in outer orbit witch they want to give away to have saturated inner orbit so they become charged by induction. Plastic being carbon polymer have four electrons in outer orbit and does not want to give electrons or it will remain with only two electrons left as compared to six protons making it highly electrically positive. Plastic material cannot become charged.
How can you tell if an element will conduct energy?
Elements are in fact a bundle of energy if you will. I believe what your asking is How can you tell if an element will conduct electricity. If an atom contains less the the required atoms for its outer shell to become full and stable, it is classified as a conductor. Here's why: The atoms of a given element is composed of the protons, neutrons, and electrons. Electrons are the "electricity" part of an atom. These electrons orbit the protons and neutrons that are at the center of the atom. The electrons are in Valence shells, which is basically which orbit the electrons are on, the closest shell/orbit can contain only 2 electrons, and then it is said to be stable and full; the second valence shell/orbit can only contain 8 electrons, and then it is said to be stable and full; the third valence shell/orbit can only contain 8 electrons, and then it is said to be stable and full also ect.... Now, if we took the third valence shell, and it only contained 1 electron, it is NOT stable and full, so this 1 electron/electricity-part-of-the-atom is free to float around to other empty shells. This is due to the fact that the electrons always want to be in a stable shell/orbit. Some atoms of certain elements naturally contain a full AND therefore stable outer valence shell, (the furthest shell/orbit away.) If an atom contains less the the required atoms for its outer shell to become full and stable, it is classified as a conductor.

Why do elements on the left side of the periodic give away electrons?
The attraction between the atomic nucleus and electrons is less strong.

Are stars matter?
No. There are four "states" of matter; solid, liquid, gas, and plasma. Plasma is the state of extremely hot gasses in which the electrons have been stripped away from the atomic nuclei, causing the nuclei and electrons to exist in a kind of super-heated nuclear soup. Stars are "plasma".
Why metal is the best conductor of heat and electricity?
You have configuration of the elements. There can be eight electrons in the outermost orbit of the element. The metals have one, two or three electrons in the outermost orbit. So they want to give away those extra electrons. These are free electrons. These free electrons make the metals good conductors of heat and electricity.
What information does the atomic number of an element give you?
The atomic number is how many protons there are, and since the number of protons is equal to the number of electrons, it is also the number of electrons. You can take the number of protons away from the atomic weight (overall weight) which will give you the number of neutrons. (Electrons don't weigh anything in the atomic weight so you don't need to subtract this as well). Hope this helps :D
How does electrons shielding affect atomic size as you move down the group?
Shielding affect acts as a barrier for proton to attract electrons, therefore the electrostatic force (the which attracts electrons to protons) becomes much less and electrons become further away from the nucleus of the atom. Because of this, the atomic size increases as you move down the group.
What is the formula to get the number electrons?
The number of electrons is the same as the number of protons or the atomic number. If the element is an ion of e.g O+2, you would take away 2 from the atomic number and if it is O-2, you would add two electrons
Why do metals conduct electricity well?
Because the valence (outermost) electron shell of a metal atom is less than half full, the electrons are loosely held in that orbit and are able to break away from that atom to become 'free electrons'. These free electrons are then able to perform as charge carriers, the drift of which, we call an electric current.
How are electrons arranged in the atom?
Electrons are arranged around the atomic nucleus forming the electron clouds.
How do you get the number of neutrons in a element?
To find the number of neutrons in an atom you would subtract the protons from the atomic mass. The number of protons is equal to the atomic number.

The atomic mass - the atomic number (number of protons and electrons) = the number of neutrons
