Covalent bonds form ___________.

when two atoms share electrons; forms molecular compounds

What is the Octet Rule?

Atoms form bonds by either transferring or sharing valence electrons until each have a complete octet of 8.

Atoms tend to gain, lose, or share electrons to have a full outer shell of four electrons.

Atoms tend to gain, lose, or share electrons to have a full outer shell of ten electrons.

Atoms tend to gain, lose, or share electrons to have a full outer shell of six electrons.

subtracting 8 to the group number

What are the seven diatomic elements?

H 2, Cl 2 , Br 2 , O 2 , N 2 , I 2 , F 2

H 2 , Cl 2 , I 2 , F 2 , Hg 2 , Br 2 , Fe 2

What is a bonding pair?

A pair of electrons shared between two atoms in a covalent bond.

A pair of protons shared between two atoms in an ionic bond.

A pair of electrons that are transferred from one atom to another.

A pair of electrons that are not shared between two atoms.

A lone pair is unshared pair of electrons

A lone pair is a pair of valence electrons that are shared between two atoms.

A lone pair is a pair of valence electrons that are involved in bonding and are localized on a specific atom.

A lone pair is a pair of valence electrons that are not localized on a specific atom and are free to move throughout the molecule.

What is the process of the Lewis Dot Structures of Molecules?

Find the sum of valence electrons, draw bonding electron dots first, distribute remaining electron dots in pairs until each atom has an octet (8) or each hydrogen atom has a duet (2).

Counting the number of protons in the molecule and placing them around the atomic symbol.

Drawing the Lewis Dot Structure by randomly placing the valence electrons.

Determining the number of neutrons in the molecule and placing them around the atomic symbol.

What is the VSEPR Theory?

The VSEPR Theory is the repulsion between electron pairs causes molecular shapes to adjust, so that they stay far part as possible. Lone pairs take up more space, therefore responsible for repelling bonds.

The VSEPR Theory is a model used in chemistry to predict the boiling point of molecules based on the repulsion between electron pairs in the valence shell of an atom.

The VSEPR Theory is a model used in chemistry to predict the size of molecules based on the repulsion between electron pairs in the valence shell of an atom.

The VSEPR Theory is a model used in chemistry to predict the color of molecules based on the repulsion between electron pairs in the valence shell of an atom.

What does VSEPR represent?

Valence Shell Electron Pair Repulsion

Valence Shell Electron Pair Regulation

Valence Shell Electron Pair Reaction

Volatile Shell Electron Pair Repulsion

What is a double bond?

A double bond is two shared pairs of electrons, represented by 2 dashes (or 4 electron dots)

A double bond is a type of chemical bond where three pairs of electrons are shared between two atoms.

A double bond is a type of chemical bond where only one pair of electrons is shared between two atoms.

A double bond is a type of chemical bond where electrons are not shared between two atoms.

What is a triple bond?

A triple bond is three shared pairs of electrons, represented by 3 dashes (or 6 electron dots)

A triple bond is a chemical bond between three atoms involving nine bonding electrons instead of the usual two in a covalent single bond.

A triple bond is a chemical bond between two atoms involving three bonding electrons instead of the usual two in a covalent single bond.

A triple bond is a chemical bond between two atoms involving four bonding electrons instead of the usual two in a covalent single bond.

What is the bond dissociation energy?

The energy required to break a covalent bond.

The energy released when a chemical bond is formed.

The energy required to break a covalent bond.

The energy required to form a chemical bond.
