This is because an electron is negatively charged, the nucleus(centre of the atom) is positively charged, opposite charges attract....thus the electrons stay in orbit like the earth around the sun because of forces of attraction (in this case charges)

∙ 7y agoThis is mainly because electrons are in constant motion... the free electrons help us in transmission of electricity.. electrons also play a great role in forming compounds as only the number of electrons in the outer shell decide the valency of elements.
If electrons were bound to a nucleus, we would need a lot of energy to form compounds, as then we would have to break down the nucleus to set the electrons free.
The electrons, with their negative charge, have to remain separate from the positively-charged protons of the nucleus so that charge can be carried and transmitted.

The big elements lose their electrons easier because the electrons in the outer shells (orbitals) are further away from the nucleus and therefore easier displaced.

Wiki User
∙ 12y agoThere are two forces.
- electrostatic force between electrons and nucleus.
- Centrifugal force.
These forces balance each other.
Wiki User
∙ 14y agoBecause they are moving around the nucleus with a specific speed which creates a centrifugal force which is balanced by the centripetal force (nucleus pull).

Why do atoms give off light when they drop energy levels in an atom?
When electrons fall to a lower energy level, they give off energy in the form of light.
How does a neutral atom become a negative ion?
The positivity and negativity of an ion is determined by the number of electrons compared to that of protons. If there are more electrons than protons in the ion, it is considered negative. It becomes negative by gaining electrons, which can happen a number of ways. Simply put, most often it gains electrons by pulling them off of other elements and molecules. The more electronegative an element is, the easier it is for it to do this. Elements are most stable in their "octet" configuration where all of the available spots in an orbital are filled. Elements with less than a perfect octet will rip electrons off of other things.
How is the charge of the atom or ion determined from the number of protons neutrons and electrons present?
Atoms have protons, neutrons, and electrons. Protons and electrons have electric charge, but neutrons do not. Protons are positively charged, and electrons are negatively charged. An atom has the same number of protons and electrons. Because the atom has same amounts of positively and negatively charged particles, the atom is neutral and has no electric charge. The only time an atom becomes electrically charged is if it loses or gains protons or electrons to throw off the balance. For example, we know that hydrogen only has 1 proton, 1 neutron, and 1 electron. This hydrogen atom has not electric charge. Later on, the hydrogen atom gains a proton. This would mean that there is more positive charge than negative charge in the atom. The hydrogen atom is now electrically charged.
What change to the nucleus when it loses one electron?
Just making sure, first off, that you realize electrons are not in the nucleus. They float in the empty space around the nucleus, of an atom. But if your asking what happens to the atom once it loses an electron, the atom then has a positive charge, and becomes a positive ion. The atomic size[of the atom alone] becomes smaller due to the greater pull the protons are able to have on the electrons.
What was the plum-pudding atomic model?
The plum pudding model of the atom, forwarded by J.J. Thomson, stated that the atom was like a plum pudding. The negatively charged electrons were evenly distributed throughout a positive "web" or "soup" much like plums in plum pudding are distributed here and there in the pudding. It was Rutherford, based on his observations with the gold foil experiment, who was able to push this theory aside and cause a shift in thinking to the idea that most of the mass of the atom was concentrated in a small volume within a given atom.
What is givin off when electrons in an atom fall to a lower orbit?
Energy (in the form of photons) is given off when electrons in an atom fall to a lower energy level.
What does a halogen atom give off when it gains electrons?
NOTHING
What is the only part of the atom that can be rubbed or pulled off?
Electrons
Why would people want to strip electrons off an atom?
To get to the other side?
How light is given off by the movement of electrons in an atom?
Electron transitions release photons.
What are the charges of each part of an atom?
The nucleus of the atom has a positive charge because the protons that found in the nucleus are positive and the neutrons have no charge. The electrons on the electron cloud have a negative charge. This means the entire atom has a neutral charge to it. The atom always has the same number of protons and electrons, which means they cancel their charges out.
What is the difference between electron negativity and electrons affinity?
ok, so electron affinity is the amount of energy given off when a particular atom excepts electrons. Essentially, it is the likelihood that an atom will accept an electron, while ionization energy is how much energy is needed to take an electron off of a particular atom
Does an electron determine what element it is?
The number of protons determine which element an atom is and normally the number of electrons is equal to it. Strip an electron off an iron atom and you have an ionised iron atom.
What does ionising power mean?
Ionising power is the energy the particle has that is capable of 'knocking' electrons off an atom
How many protons and electron in a barium atom?
Hey there are 56 electrons and 56 protons in a barium atom (protons usually=electrons) also you should have a look on the Internet for a periodic table and print it off it has helped me allot.
What element has 1 electrons?
Technically, ANY atom could have "one electrons" or, as I suspect you mean to ask, one electron. In its uncharged state, a protium atom, also known as a hydrogen-1 atom, is the only atom posessing a single electron, but in theory any atom could have any number of its electrons stripped off, and be left with only one (or even none).
What happens when an atom loses an electron from its outer most shell?
well The electrons on that shell have nowhere to go so they jump off and become ionised
