Full question:
Which of the following describes a covalent bond?
a)It is the exchange of electrons between atoms with an electronegativity difference above 1.7.
b)It is the exchange of electrons between atoms with an electronegativity difference below 1.7.
c)It is the sharing of electrons between atoms with an electronegativity difference above 1.7.
d)It is the sharing of electrons between atoms with an electronegativity difference below 1.7.
Answer:
covalent bond is the sharing of electrons between atoms with an electronegativity difference below 1.7.
Explanation:
A covalent bond consists of the synchronous influence of two nuclei for one or more sets of electrons. A covalent bond, the interatomic linkage that emerges from the distribution of an electron set among two atoms. The electrons placed among the two nuclei are bonding electrons. Covalent bonds happen within the same atoms or within various atoms whose variation in electronegativity is inadequate to support the change of electrons to form ions. The partial ionic character of covalent bonds rises with the variation in the electronegativities of the two atoms.
