An atom is stable (i.e. non-reactive) when it's valence orbitals are full. An orbital is essentially an available place for an electron to orbit (or the shape of the electron 'cloud' in quantum models). The 'valence' orbital is the outside orbital of that particular atom. Atoms form stable compounds when they can share electrons to mutual advantage. For example, carbon has only 2 electrons in its valence orbitals, but has room for 6. Therefore, carbon is stable when it can form a compound with something that will let it share share 4 electrons.
What else can I help you with?
Electron sharing produces what?
Electron sharing produces covalent bonds, where atoms share electrons to achieve a stable configuration. This sharing allows atoms to fill their outer electron shells and lower their overall energy. Covalent bonds are strong and stable, contributing to the formation of molecules and compounds.
Arrange F2 F2- and F2 plus in order of decreasing stability?
F2 < F2- < F2+. This is because F2 has no extra electrons or missing electrons, while F2- has an extra electron making it more stable than F2. F2+ is the least stable as it has lost an electron, creating an electron deficiency.
When electrons are shared the type of bonding is called?
Chemical bonds are what form molecules from constituent atoms. When atoms share electrons the type of inter-molecular attraction is called a covalent bond.
Why does the oxidation of organic compounds by molecular oxygen to produce CO2 and water release free energy?
The oxidation of organic compounds by molecular oxygen releases free energy because the bonds in the organic compounds are more stable than the bonds in the products (CO2 and water). When the organic compounds are oxidized, new bonds are formed and energy is released in the process. This energy is made available for cellular processes such as ATP production.
The reactivity of an atom arises from what?
The reactivity of an atom arises from its electron configuration. Atoms with incomplete outer electron shells are more reactive as they tend to gain, lose, or share electrons to achieve a stable electron configuration. This behavior is driven by the atom's desire to reach a more stable state, typically following the octet rule.
What are the smallest units of covalent molecular compounds called?
The smallest units of covalent molecular compounds are called molecules. They are formed when atoms share electrons to achieve a stable electron configuration.
How are molecular compounds held together?
Molecular compounds are held together by covalent bonds, which are formed when atoms share electrons to achieve a stable electron configuration. These bonds involve the sharing of electron pairs between atoms, creating a strong bond that holds the atoms together in a molecule.
Why are electrons shared in molecular compounds?
The sharing of electrons is what makes them molecular compounds. If they didn't share, then they would be ionic compounds. So, depending on what atoms or elements are bonding together, you will have sharing or not. Whether they share or not is more complicated, but has to do with electronegativity and electron configurations.
What is a pseudo-noble gas?
Although the formation of an octet is the most stable electron configuration, other electron configurations provide stability. These relatively stable electron arrangements are referred to a pseudo-noble gas configuration. Although the formation of an octet is the most stable electron configuration, other electron configurations provide stability. These relatively stable electron arrangements are referred to a pseudo-noble gas configuration.
When compounds form what is one result for the atoms that bonded?
It Has An Stable Arrangements Of Electrons
What compounds compound would be covalently bonded?
Compounds containing nonmetals typically form covalent bonds, such as methane (CH4), water (H2O), and carbon dioxide (CO2). These compounds share electrons between atoms to achieve a stable electron configuration.
Why are the noble gases are not found as a compounds?
They have very stable electron configuration. They does not tend to make compounds.
Is covalent molecular?
A covalent bond is one in which atoms within a molecule share pairs of electrons (hence the term covalent or "mutual electron state"). It is not clear to me what is meant by "molecular" in your question, but the bond is intramolecular(or inside the molecule). A covalent bond is a type of molecular bond, if that is the question.
What is binary compounds containing two non metals?
Binary compounds containing two nonmetals are typically covalent compounds where the atoms share electrons to achieve a stable electron configuration. These compounds tend to have lower melting and boiling points compared to ionic compounds. Examples include water (H2O), carbon dioxide (CO2), and ammonia (NH3).
What is the oxidation state of potassium in ionic compounds?
Potassium typically has an oxidation state of +1 in ionic compounds due to its tendency to lose one electron to achieve a stable electron configuration.
Why are compounds good insulators?
Compounds with tightly bound electrons have low electrical conductivity, making them good insulators. Their stable electron configuration prevents the flow of electric current through the material. Additionally, compounds with high molecular structures create barriers, hindering the movement of electrons and heat transfer.
