They are easily lost because they are the furthest away from the nucleus, making them the easiest to remove. To visualize that, imagine you have paperclips around a magnet. The furthest one will be the easiest to take off, and it will become harder to take them away as they get closer to the magnet.

∙ 13y agoIn order to be stable most atoms want an outer valence shell with 8 electrons. An atom such as Cl has 7 electrons in its outer shell. It would be much more energetically favorable for it to gain one electron to have 8 in its outer shell, rather than to strip away 7 electrons to have 8 in its outer shell.

What is an atom called that has lost valence electrons?
isotope?
Number of electrons lost or gained by an atom in a chemical reaction is its?
Number of electrons are lost by an atom in a chemichl reaction
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.
An atom or a molecule that has gained or lost one or more electrons is called?
When an atom gains or loses electrons, it is trying establish a more stable situation in which it has a full valence shell. An atom that has gained or lost valence electrons is called an ion. When a positive ion and a negative ion can bond due to their opposite charges. This is called an ionic bond.
What is the electrons in the outer most energy level of an atom called?
valence electrons.. every element wants to have 8 which is why there are ions and such.. elements which already have 8 to begin with are called noble gases and can be found on the last column on the periodic table :)
Why does valence electron give up outermost energy easily?
The force of attraction between the atom's nucleus and its valence electrons are the least. Hence valence electrons are lost easily.
What is an atom called that has lost valence electrons?
isotope?
Number of electrons lost or gained by an atom in a chemical reaction is its?
Number of electrons are lost by an atom in a chemichl reaction
Is the reactivity of a metal depend on how easily it loses its valence electrons?
yes it does. if the electrons are lost easily, reactivity is more.
What change in electron structure occures when a sodium atom becomes a sodium ion?
The valence electrons are either lost to another atom or the sodium atom gains valence electrons, it really depends on if what the sodium atom is bonding with has a lot or a little of valence electrons. The structure doesn't change though, just the number of valence electrons change. The nucleus is never changed when an ion is formed.
If valence electrons are gained or lost the atom becomes a charged particle called a?
an ion.
What is an atom that has lost or gained one or more valence electrons called?
covalent bonds
Is electrons share unequally in ionic bond?
Yes, The electrons are unequally shared in an Ionic Bond. One atom has more electrons than the other atom. Every Atom has Electrons that are called Valence Electrons. These Valence Electrons are the electrons in the outer shell of the Bohr Model of the atom. There should be a stable number of Valence electrons (2 or 8) for an atom to be completely stable. To stabilize the valence electrons the atom bonds with other atoms. One type of bond is called ionic bond where one atom gives up a certain number of electrons to be stable and another atom gains all of those lost atoms.
What is the number of electrons a calcium atom must gain or lose to have 8 valence electrons?
two electron should be lost
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.
What is happening to valence electrons in a purely ionic bond?
In the atom which will form the positive ion, the valence electrons is/are being given up and lost to the reaction medium (environment). In the atom which will form the negative ion, the valence electrons lingering in the reaction medium will be attracted to the proton of the negative ion and is taken in by the negative ion.
What is the difference between ion nd atom?
An ion is certain type of atom. Ions are atoms that have lost or gained electrons (often to have 8 valence electrons in the s and p orbitals).
