Which of the following is the best explanation for a covalent bond? A)electrons simultaneously attracted by more than one nucleus B)an interaction between outer electrons C)the overlapping of unoccupied orbitals of two or more atoms D)the overlapping of two electron-filled orbitals having different energies E)a positive ion attracting negative ions A single covalent bond is the sharing of two electrons, a double covalent bond is the sharing of four electrons, and triple covalent bond is the sharing of six electrons. Let's look at an example of a triple bond. Nitrogen gas is also a diatomic molecule. The chemical formula for nitrogen gas is N 2.

A very poor question....even by the standards of most multiple choice questions.....I would plump for C..... The choice is between C and D. Dinitrogen gas is moderately reactive; much less reactive than dioxygen.
Covalent bonding is a form of chemical bonding between two non metallic atoms which is characterized by the sharing of pairs of electrons between atoms and other covalent bonds. Ionic bond, also known as electrovalent bond is a type of bond formed from the electrostatic attraction between oppositely charged ions in a chemical compound. pi bond Covalent Bonding Section 9.1 The Covalent Bond In your textbook, read about the nature of covalent bonds. Use each of the terms below just once to complete the passage. covalent bond molecule sigma bond exothermic When sharing of electrons occurs, the attachment between atoms that results is called a(n) (1)

For middle grades. The combining of elements to form different substances is called chemical bonding. The world around you is made up of thousands and thousands of different compounds formed from chemical bonds. There are three types of chemical bonds: ionic bonding, covalent bonding and metallic bonding. This quiz will focus on covalent bonding. Covalent Bonds Ionic bonds hold atoms together through electrostatic forces. Covalent bonds operate through an entirely different means: the sharing of electrons. By sharing electrons, two atoms can mutually complete their valence shells to become more stable. A molecule is a collection of atoms held together by covalent bonds.
