When atoms do not have a full valence shell, the atoms are more likely to react with other different atoms to form chemical bonds. The only atoms that do have a full valence shell are the noble gases, and they are the least reactive of all atoms.

It becomes stable (stable= not likely to react) and an ion. If you add electrons to make it full it's an anion (negative charge) , and i f you take away electrons to make it full it's a cation(positive charge)

An atom with a full valence shell is a stable atom. It won't bond anymore and is considered stable. The noble gases all have full valence shells.

No often but they can. There are some noble gas compounds such as xenon tetrafluoride (XeF4), but may of these compounds are unstable.

What is an electron called in the outermost energy level?

They are called valence electrons, and they are responsible for an atom's chemical properties. During a chemical reaction, the valence electrons are the only part of an atom that participates.

What is an incomplete octet?

B in BH3 has an incomplete octet because it only has 6 valence electrons. 3 of its own and 1 from each hydrogen The central atom does not have 8 valence electron in the molecule.

How is the valence electrons of an atom related to a chemical bonding?

The valence electrons are the only electrons that are involved in chemical bonding. These electrons can be shared or transferred. A simple rule of thumb is that atoms "strive" to attain the octet either by loss gain or sharing of electrons.


What does it mean when an elements has 8 valence electrons?

It means that there are 8 electrons in the outer most shell of the atom. Atoms with 8 valence electrons are generally stable.


Can a Neutral unbonded atom complete valence octet?

if it is a noble gas it already has an octet, otherwise, it would need to gain or use electrons to complete an octet and would no longer be neutral or unbounded.


What does the atom of an element belonging to the noble gas family have?

A complete octet of electrons (8) in the outer-most, or valence, shell.


Which three elements violate the octet rule?

The octet rule cannot be satisfied in molecules whose total number of valence electrons is an odd number.There are also molecules in which an atom has fewer, or more, than an octet of valence electrons.


How many valence electrons are in an atom of magnesuim?

There are 2 valence electrons in an atom of magnesium. There are 5 valence electrons that are in an atom of phosphorus. There are 4 valence electrons that are in a silicon atom.
