Concept explainers
To analyze:
The unequal sharing of electrons forms a polar covalent bond.
Introduction:
An element is a pure substance of one type of atom or it is a species of an atom having the same number of protons in its atomic nucleus. For example, there are 118 known elements in the periodic table.
A compound is the combination of two or more different elements.
A covalent bond is formed when same or different elements share electrons. For example, water (), in which two hydrogen atoms are joined with one oxygen atom or sharing of electrons takes place.
A molecule is the combination of two or more of the same type of elements.
For example, is the combination of two hydrogen atoms.
Octet rule: It is a rule which is followed when compound formation occurs. According to this rule, atoms of main-group elements tend to combine in such a way that each atom has eight electrons in its valence shell, giving it the same electron configuration as a noble gas.
The electronic configuration is the arrangement of electrons according to the increasing energies of the orbitals
Electronegativity is the tendency of an atom to attract a shared pair of electrons.
