Atoms have different shells in order to prevent matter from collapsing to an extremely dense state. The increasing complexity of each shell allows for more electrons to be included.
Pauli exclusion principle states that no two electrons in an atom can have identical quantum numbers. Only one electron can occupy a given quantum state at a time. That is, each electron in an atom has a unique set of quantum numbers.
If there is no unique energy level for each electron, all of the electrons in an atom would pile up in the lowest energy state leading to collapse of matter.

How many valence electrons does a neutral oxygen atom have?
A neutral atom of oxygen would have 6 valence electrons.
What factor dertemines that an oxygen atom can form two covalent bonds while a carbon atom can form four?
It is the number of unpaired electrons in their valence shells. Oxygen has two unpaired valence electrons and carbon has four unpaired valence electrons.
What cause's and creates an ionic bond?
The complete transference of electrons from valence shell of one atom to the valence shell of another atom FORMS IONIC BOND....
How many electrons are needed to complete valence shell of fluorine atom?
One
How many covalent bonds does a carbon atom need to complete its valence shell?
only 2
What is the value of n for the valence shells of as?
The value of 'n' for the valence shells is the number of shells that specific atom has
How many valence shells does an atom has?
The valence shell is the outermost shell...and an atom can only have one outer shell.
What are valence electrons and shells?
Valence electrons are the ones which participate in chemical reactions in some way, either by moving from one atom to another, or by being shared with another atom. They are found in the outer shell of an atom (there are usually inner shells with other electrons that are not valence electrons, although in the lightest elements, there are no inner shells and all electrons are valence electrons).
What do bromine and chlorine have in common?
The atoms of both elements have seven valence electrons and a strong tendency to abstract, from a less electronegative atom, an electron to complete their valence shells and thereby become an anion.
What is part of an atom that move around the outer shells?
the valence electrons
What are valence shells?
Electrons in the outermost orbitals of an atom. They determine the chemical reactivity of an atom and are the primary electrons that participate in chemical reactions.
What are valence and electrons?
Valence electrons are the ones which participate in chemical reactions in some way, either by moving from one atom to another, or by being shared with another atom. They are found in the outer shell of an atom (there are usually inner shells with other electrons that are not valence electrons, although in the lightest elements, there are no inner shells and all electrons are valence electrons).
What is an atom core?
An atom stripped of its valence electrons, so that its remaining electrons are all in closed shells.
What are cores?
An atom stripped of its valence electrons, so that its remaining electrons are all in closed shells.
What are the the three types of particles and where in the atom are they found?
protons, in nucleus electrons, in the valence shells protons, in nucleus
How many valence electrons does a neutral oxygen atom have?
A neutral atom of oxygen would have 6 valence electrons.
Do noble gases have valence shells?
Yes they have eight electrons in their valence shells. This is why they are not reactive. All elements have valence shells.
