they share electrons with the other atom they're combining with
Ionic Bond
ionic bond
covalent bonds always share electrons.
an ionic bond forms
Argon is a noble gas and does not have a defined electronegativity value since it does not typically form chemical bonds. Electronegativity is a measure of an element's ability to attract electrons in a chemical bond, which is not relevant for noble gases like argon.
The electrons (especially the valence electrons)
No. A chemical bond forms from the sharing or transferring of the outermost electrons of two or more elements.
no chemical reaction takes place . when electrons are shared it is known as covalent bond
Valence Electrons
Valence Electrons

Copper isn't a chemical bond, its an element
