Chemical Bonding Flashcard

Front

What is the atomic number of an element?

Back

The atomic number is the number of protons in the nucleus of an atom.

Front

What part of the atom is involved in bonding?

Back

The part of the atom involved in bonding is the valence electrons.

Front

How many electrons can the first electron shell hold?

Back

The first electron shell can hold a maximum of two electrons.

Front

What are valence electrons?

Back

Valence electrons are the electrons in the outermost shell of an atom that can participate in forming bonds.

Front

What happens in ionic bonding?

Back

In ionic bonding, electrons are transferred from one atom to another, resulting in the formation of ions.

Front

What is a covalent bond?

Back

A covalent bond is a type of chemical bond where two atoms share one or more pairs of electrons.

Front

What is the octet rule?

Back

The octet rule states that atoms tend to bond in such a way that they have eight electrons in their valence shell, achieving a stable electron configuration.

Front

What is the difference between ionic and covalent bonds?

Back

Ionic bonds involve the transfer of electrons and the formation of charged ions, while covalent bonds involve the sharing of electrons between atoms.

Front

What is electronegativity?

Back

Electronegativity is a measure of an atom's ability to attract and hold onto electrons in a chemical bond.

Front

What is a polar covalent bond?

Back

A polar covalent bond is a type of covalent bond where the electrons are shared unequally between the two atoms, resulting in a partial charge.
