covalent bonding

Front

What is covalent bonding?

Back

Covalent bonding is a type of chemical bond where two atoms share one or more pairs of electrons to achieve a full valence shell.

Front

What do atoms contribute in covalent bonding to achieve a full valence shell?

Back

Each atom contributes one valence electron.

Front

How do covalent bonds form?

Back

Covalent bonds form by sharing valence electrons between atoms.

Front

What does an electron dot diagram represent?

Back

An electron dot diagram represents the valence electrons of an atom and how they are shared in covalent bonds.

Front

What does two pairs of shared electrons represent in an electron dot diagram?

Back

Two pairs of shared electrons represent a double bond.

Front

What is a sigma bond?

Back

A sigma bond is the first bond formed between two atoms, created by the head-on overlap of atomic orbitals.

Front

How many sigma bonds are in a molecule with three single bonds?

Back

There are 3 sigma bonds.

Front

What type of compound is formed between a metal and a nonmetal?

Back

A metal and nonmetal compound is an ionic compound.

Front

What is the difference between ionic and covalent compounds?

Back

Ionic compounds are formed by the transfer of electrons, while covalent compounds are formed by the sharing of electrons.

Front

What is a triple bond?

Back

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