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.
Atoms with eight valence electrons form compounds easily?
Atoms with eight valence electrons are considered to be stable because they have a full outer electron shell, following the octet rule. These atoms are less likely to react with other atoms to form compounds, as they already have a complete electron configuration.
What would alkali metal atoms need in order to end up with the same stable electron arrangements as the noble gas?
Alkali metal atoms need to lose one electron to achieve the stable electron arrangement of the nearest noble gas. This is because the noble gases have a full valence shell, which is more stable. By losing an electron, the alkali metal atoms achieve a full valence shell and become more stable.
How do atoms attains stable configuration of noble gas?
Atoms attain stable configuration of noble gas by gaining or losing electrons to achieve a full outer electron shell, often referred to as an octet. This stable arrangement mimics the electron configuration of noble gases and provides the atom with increased stability and lower energy. This can be achieved through ionization (loss or gain of electrons) or bonding with other atoms to share electrons.
What are three reasons why atoms bond?
they give an electron or two to the other atom, share an electron or two with another atom of (if they're both metals) lose all their outer shell electrons and form a load of 'positive ions in a sea of electrons'
When compounds form what is one result for the atoms that bonded?
It Has An Stable Arrangements Of Electrons
How do the atoms in molecular compounds form stable electron arrangements?
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.
Does oxygen atoms become more stable or less stable when oxygen forms compounds?
Oxygen atoms become more stable when they form compounds because they are able to complete their valence shell by sharing electrons with other atoms. This allows them to achieve a full outer electron shell and become more like the stable noble gases.
Why do atoms form compound instead of existing as single atoms?
Every element has an electron configuration based on the number of electrons it has. However, the electron configurations of most elements are at least somewhat unstable. To obtain a more stable configuration, atoms will either share, give, or steal electrons in bonds with other atoms. In short: compounds are generally more stable than single atoms.

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.
How do compounds form in a covalent bond?
Compounds form in a covalent bond when two or more atoms share electrons to achieve a more stable electron configuration. In a covalent bond, the shared electrons are attracted to the nuclei of both atoms, holding the atoms together in a stable molecule.
Why are electrons shared in covalent compounds?
Electrons are shared in covalent compounds to achieve a stable electron configuration for all atoms involved. By sharing electrons, each atom can complete its outer shell and attain a full valence shell, leading to increased stability and reduced overall energy.
What would alkali metal atoms need in order to end up with the same stable electron arrangements as the noble gas?
Alkali metal atoms need to lose one electron to achieve the stable electron arrangement of the nearest noble gas. This is because the noble gases have a full valence shell, which is more stable. By losing an electron, the alkali metal atoms achieve a full valence shell and become more stable.
Chemically inert atoms always have their outermost electron shell full?
This statement is generally true. Chemically inert atoms, such as the noble gases, have a full outer electron shell, which makes them stable and less likely to react with other atoms to form compounds.

This stable arrangement mimics the electron configuration of noble gases and provides the atom with increased stability and lower energy.
