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.
What else can I help you with?
How many valence electrons does a neutral oxygen atom have?
A neutral atom of oxygen would have 6 valence electrons.
How can one differentiate valence electrons from electron configuration?
Valence electrons are the outermost electrons in an atom that are involved in chemical bonding, while electron configuration refers to the arrangement of electrons in an atom's energy levels or shells.
Which kind of bond electrons given or taken?
In an ionic bond, electrons are transferred from one atom to another, resulting in one atom gaining electrons (anion) and the other atom losing electrons (cation). In a covalent bond, electrons are shared between atoms, allowing them to complete their valence shells.
What kind of bond exists between a boron atom and an iodine atom?
A covalent bond exists between a boron atom and an iodine atom. In this bond, the atoms share an electron pair to achieve a stable electronic configuration. Boron has 3 valence electrons, while iodine has 7, so they can share electrons to complete their outer electron shells.
What is the reactivity of an atom determined by?
The reactivity of an atom is determined by the number of electrons in its outer energy level (valence electrons). Atoms with incomplete valence shells tend to be more reactive as they seek to gain, lose, or share electrons to achieve a stable electron configuration. Electrons in the outermost energy level are involved in chemical reactions.
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 is part of an atom that move around the outer shells?
the valence electrons
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
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 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.
How can one differentiate valence electrons from electron configuration?
Valence electrons are the outermost electrons in an atom that are involved in chemical bonding, while electron configuration refers to the arrangement of electrons in an atom's energy levels or shells.
