Which symbols represents a chlorine ion with a stable arrangement of eight valence electrons?
Cl-
How can you use the word stable to explain why the alkali metals tend to lose valence electrons?
Alkali metals, have only one valence electron so they will "want" to lose it to achieve a stable electron arrangement.
How many Valence electrons in a stable octet?
8 valence electrons
The inertness of the noble gases is due to?
Noble gases are inert because they contain a "stable octet" of electrons in the outermost shell of the atom (valence electrons). This means that the noble gases do not need to react to lose or gain electrons in order to become stable, since scientists have determined that 8 valence electrons is a stable electron configuration.
Most atoms need eight valence electrons to be stable is called what?
Octet Rule!
Why is helium stable with a different arrangement?
All noble gases have completely filled orbitals. Helium has two valence electrons and its s-orbital is full and is stable. Other noble gases have completely fill p-orbitals as the valence orbitals.
When an atom or an ion has 8 valence electrons it is more or less stable than when it ha fewer than eight valence electrons?
Valence electrons are the amount of electrons in the outermost electron shell. 8 valence electrons fill the outer shell making it completely stable.
How many valence electrons do stable atoms have?
A stable atom has 8 electrons in its outer most valence shell. A simple way to remember this is that all atoms want to be like the noble gases which all have 8 electrons (except helium but the reason is complicated and not necessary here)
What number of valence electrons that carbon has?
Neutral Carbon atoms contain 6 electrons and 6 protons 2 electrons are found in the 1st electron ring and 4 in the outer ring to reach a stable electron (8 in the outershell) arrangement carbon requires 4 covalent bonds to be formed
How many valence electrons will result in chemical stability for an atom?
An atom requires 8 valence electrons to be chemically stable. The elements with 8 valence electrons are the Noble Gases, and they are both stable and largely unreactive.
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.
Where is the most Stable outer orbital arrangement of electrons?
The noble gases - group 18 on most newer periodic tables - are the most stable. They have a completely filled valence shell of electrons.
