Chemistry Flashcard U2

Front

Which element is most likely to form a covalent bond?

Back

Chlorine

Front

What is the name of HNO₂ and why?

Back

Nitrous acid, because it is a weak acid.

Front

What is a property of covalent compounds?

Back

Low boiling points.

Front

Why does ionization energy increase when moving from left to right across a row of the Periodic Table?

Back

Due to increasing nuclear charge.

Front

What is a type of intermolecular force?

Back

Van der Waals forces.

Front

Define covalent bond.

Back

A covalent bond is a chemical bond that involves the sharing of electron pairs between atoms.

Front

What is the difference between ionic and covalent bonds?

Back

Ionic bonds involve the transfer of electrons from one atom to another, while covalent bonds involve the sharing of electrons.

Front

What are the characteristics of ionic compounds?

Back

Ionic compounds typically have high melting and boiling points, and they conduct electricity when dissolved in water.

Front

What is the significance of electronegativity in covalent bonding?

Back

Electronegativity determines how strongly an atom attracts shared electrons in a bond.

Front

What are intermolecular forces?

Back

Intermolecular forces are forces of attraction or repulsion between neighboring particles (atoms, molecules, or ions).
