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 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 :)
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 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 are Atoms that carry an electrical charge called because they have gained or lost electrons?
Atoms that carry an electrical charge because they gained or lost electrons are called ions. An atom that has lost electrons will be positively charged, and it is called cation. On the other hand, an atom that has gained electrons will be negatively charged, and it is called anion.
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
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.

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 :)
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.
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 the number of electrons a calcium atom must gain or lose to have 8 valence electrons?
two electron should be lost

What is an ion that has lost or gained electrons called?
An atom that has gained or lost electrons is called an ion. An atom that has gained one or more electrons becomes a negatively charged ion called an anion. An atom that has lost one or more electrons becomes a positively charged ion called a cation.
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.
