Why do elements with a completely full outer shell of electrons do not usually bond with other elements to form compounds?
Because they don't chemically react with anything to form a compound.
---------------------------------------------
And the reason they don't react or form compounds is because noble gases have a filled outer-most electron shell. The reason that all other elements react via ionic bonding, molecular bonding or metallic bonding is to achieve a filled outer-most electron shell. Since the noble gases already have that, they don't need to react. However, that doesn't mean that they never react. Large noble gases have loosely-held outer-most electrons and they can react with small, very electronegative elements to form compounds. Examples include xenon difluoride (XeF2), xenon hexafluoride (XeF6), etc.
What else can I help you with?
Molecular compounds are usually .?
composed of two or more nonmetallic elements.
Is boron covalent?
Yes, boron typically forms covalent bonds. It has only three valence electrons, so it tends to share electrons with other elements to complete its octet. This usually results in the formation of covalent compounds.
Why do elements pair together to form compounds?
Elements form compounds by sharing, gaining, or losing electrons to achieve a stable configuration, usually following the octet rule (having 8 electrons in their outermost shell). This stability is achieved by filling their outer electron shell, which allows them to have a lower energy state and increased stability compared to their individual atoms.
Does covalent compounds have a high or low electronegativity?
In comparison with ionic bonds, the difference in electronegativities of elements in a covalent bond have a lower difference in electronegativities. A covalent bond occurs between two nonmetals that have a difference in electronegativities that is 1.7 or less. Usually an ionic bond has a difference in electronegativities that is greater than 1.7, but not always.
The valence electrons largely determine the chemical properties of an element and are usually the only electron used in?
The valence electrons are involved in forming chemical bonds between atoms. They determine an element's reactivity and ability to combine with other elements to form compounds. In general, only the outermost electrons, known as valence electrons, participate in chemical reactions.
What do metals do when it comes to electrons?
When forming compounds, metal atoms usually donate some of their electrons to atoms of more electronegative elements to form compounds with ionic bonds. some metals can share electrons with other elements to form at least partially covalently bonded compounds. In elemental form, metal atoms share their electrons in what is called a "sea of electrons" that extends throughout the volume of a piece of elemental metal.
Inorganic compounds are usually mad from elements other than what?
Inorganic compounds - usually made from elements other than
What other elements does heulium usually mix with in compounds?
Helium is a member of the noble gas family of elements. The elements of this family do NOT usually form compounds with other elements.
Molecular compounds are usually .?
composed of two or more nonmetallic elements.
Is boron covalent?
Yes, boron typically forms covalent bonds. It has only three valence electrons, so it tends to share electrons with other elements to complete its octet. This usually results in the formation of covalent compounds.
Do noble gases usually react with other elements why or why not?
Noble gases have completely filled orbitals / energy levels. They generally have 8 valence electrons (helium has only 2) and have stable electronic configuration. Hence they are chemically inert and generally do not form compounds under normal conditions.
An element referred to as a nonmetal usually forms compounds by what?
Sharing electrons
Why do elements pair together to form compounds?

Is chalk composed of elements or compounds?
A compound. Usually calcium carbonate.
How are usually found?
In the nature the majority of chemical elements are found as compounds.
Does covalent compounds have a high or low electronegativity?
In comparison with ionic bonds, the difference in electronegativities of elements in a covalent bond have a lower difference in electronegativities. A covalent bond occurs between two nonmetals that have a difference in electronegativities that is 1.7 or less. Usually an ionic bond has a difference in electronegativities that is greater than 1.7, but not always.
When elements react what are given away?
Oh, dude, when elements react, they give away or take electrons to achieve a stable configuration. It's like a high-stakes game of electron trading - one element might be like, "Here, take my electron, I don't need it," while another is all, "Thanks, I'll add this to my collection." So yeah, electrons are the hot commodity in the world of chemical reactions.
