Electrons, which are usually associated with the positive nuclei of atoms, can occasionally jump up or down in their orbitals, or participate in numerous forms bonding with other atoms, which requires their re-positioning; a common model for good conductors such as metals describes nuclei in fixed positions with valence electrons around them somewhat like a "sea" and not necessarily associated with any specific atom - thus free to move and thus create a current when an electromotive force is applied.
Electrons are also located away from atoms, usually then termed 'dissociated' - nuclei may emit them as a form of ionizing radiation in beta decay; they may be removed by heat, radiation, or other effects; electrons are a component of cosmic rays, freely moving high energy particles in space, although they represent only a small fraction of particles which make up cosmic radiation.
What else can I help you with?
What particles around the atom have negative charge?
only the electrons have a negative charge but they go around the nucleus
How many electrons can the inner shell of an atom contain?
The very inner shell of an atom is the 1st shell and can only contain 2 electrons.
Which atom has the weakest attraction for the electrons ina bond with an H atom?
Helium has the weakest attraction for electrons in a bond with a hydrogen atom because it has only two electrons and a full valence shell, making it stable and less likely to attract additional electrons.
What is co-ordinate bonding?
it is a type of covalent bond in which sharing of electrons takes place
How many electrons do calcium has?
Calcium, as an element, has 20 electrons. But when becomes an ion, it loses two electrons, becoming Ca+2. Therefore, as an ion, calcium has only 18 electrons.18
Is an atom only electrons that can be moved from place to place?
No. An atom consists of protons, neutrons and electrons.Electrons can, in certain circumstances, be moved or shared with other atoms. This is the basis of chemistry and electricity.
Which atom has only 6 electrons?
The neutral atom is Carbon, but other ions can have only 6 electrons.
How many electrons in an atom of flourine-19?
A fluorine atom has 9 electrons and it has the only isotope, fluorine-19.
What particles around the atom have negative charge?
only the electrons have a negative charge but they go around the nucleus
How many electrons can the inner shell of an atom contain?
The very inner shell of an atom is the 1st shell and can only contain 2 electrons.
Which atom has the weakest attraction for the electrons ina bond with an H atom?
Helium has the weakest attraction for electrons in a bond with a hydrogen atom because it has only two electrons and a full valence shell, making it stable and less likely to attract additional electrons.
What are the electrons in the outermost she'll of an atom called?
Valence electrons are the electrons in the outermost shell of an atom. The ones in the inner shell are known as core electrons.
Which of the electrons only allows a total of 2 electrons?
I think you mean what atom only allows a total of 2 electrons and that would be helium.
How many unpaired electrons are present in a neutral mercury atom?
There are no unpaired electrons in an unexcited neutral mercury atom; its outer shell contains only two s electrons that are paired, as are all the electrons in the filled inner shells of the atom.
What is co-ordinate bonding?
it is a type of covalent bond in which sharing of electrons takes place
To make static electricity what is the only part of the atom that moves?
In static electricity, the only part of the atom that moves is the electrons. When two surfaces rub against each other, electrons can move from one material to the other, leading to a buildup of static charge.
How many electrons are there in the helium atom?
7 Helium contains two electrons in all naturally occurring states.
