Covalent bond definition, the bond formed by the sharing of a pair of electrons by two atoms. Predict whether the following bonds will be ionic, polar covalent, or non-polar covalent. The ammonium ion, NH 4 + , is formed when a hydrogen ion (H + ) attaches to the lone pair of an ammonia (NH 3 ) molecule in a coordinate covalent bond. Draw the Lewis Dot Diagram for the following ionic compou s: a. NaF b. caC12 c. A1203 3.

This type of bond may also be found in other chemical species, such as radicals and macromolecules. The binding arises from the electrostatic attraction of their nuclei for the same electrons. Sometimes this sharing is unequal, and the bond is said to be polar.

A covalent bond, also called a molecular bond, is a chemical bond that involves the sharing of electron pairs between atoms.These electron pairs are known as shared pairs or bonding pairs, and the stable balance of attractive and repulsive forces between atoms, when they share electrons, is known as covalent bonding. Differentiate between an ordinary covalent bond and a coordinate covalent bond. Covalent bond, in chemistry, the interatomic linkage that results from the sharing of an electron pair between two atoms. Sharing is Not Always 50-50 When your mother told you to share your toys with your siblings, you may have done as she asked.


Covalent bonds form between two nonmetal atoms with identical or relatively close electronegativity values. In such a case, covalence prevails. Covalent definition, the number of electron pairs that an atom can share with other atoms. Water is one example of this unequal sharing. See more. Recall that a polyatomic ion is a group of atoms that are covalently bonded together and which carry an overall electrical charge. As a general rule, covalent bonds are formed between elements lying toward the right in the periodic table (i.e., the nonmetals). a. coordinate covalent bond d. single covalent bond b. double covalent bond e. polar bond c. structural formula f. hydrogen bond ____ 1. a depiction of the arrangement of atoms in molecules and polyatomic ions ____ 2. a covalent bond in which only one pair of electrons is shared ____ 3. a covalent bond in which two pairs of electrons are shared A bond forms when the bonded atoms have a lower … Sigma bonds also occur when an s and a p orbital share a pair of electrons or when two p orbitals that are parallel to the internuclear axis share a pair of electrons (see Figure 3-4 ). In a covalent bond, the atoms are bound by shared electrons. Learn vocabulary, terms, and more with flashcards, games, and other study tools. In a single covalent bond, when the electrons are shared between two s orbitals, the resulting bond is a sigma (σ) bond as shown in Figure 3-4. Chapter 7 terms See page 206 – Do all of the words except alloy, coordination number and metallic bond. A covalent bond may also be termed a molecular bond. b)a coordinate covalent bond is a covalent bond in which one atom contributes both bonding electrons, In a coordinate covalent bond, the shared electron pair comes from one of the bonding atoms. b)a coordinate covalent bond is a covalent bond in which one atom contributes both bonding electrons, In a coordinate covalent bond, the shared electron pair comes from one of the bonding atoms.

A covalent bond is characterized by the sharing of electrons between two atoms. A covalent bond in chemistry is a chemical link between two atoms or ions in which the electron pairs are shared between them. a. Sigma bonds are the strongest covalent chemical bonds. When is a covalent bond likely to be polar? Chapter 8 terms Covalent bond Coordinate covalent bond Diatomic molecule Double covalent bond Nonpolar covalent bond C and O polax- b. Na and Cl ionic c. B and Cl d. H H non 2. 1. A coordinate covalent bond, also known as a dative bond or coordinate bond is a kind of 2-center, 2-electron covalent bond in which the two electrons derive from the same atom.
