Chemical Bonding flashcard

Front

What type of bond is formed when electrons are transferred from one atom to another?

Back

Ionic bond.

Front

What is the primary characteristic of ionic compounds in solution?

Back

They conduct electricity when dissolved in water.

Front

In a covalent bond, how are electrons shared between atoms?

Back

Electrons are shared between two nonmetal atoms.

Front

What is the electron sea model in metallic bonding?

Back

A lattice of positive metal ions surrounded by a pool of mobile, delocalized valence electrons.

Front

How many valence electrons does Carbon have in Methane (CH4)?

Back

Four valence electrons.

Front

What happens to the valence electrons of a metal atom when it forms a cation?

Back

The electron is completely transferred to the nonmetal atom, forming a positive ion (cation).

Front

Which type of bond is characterized by a high melting point and electrical conductivity in solution?

Back

Ionic bond.

Front

What is a characteristic property of metals due to metallic bonding?

Back

They are good conductors of electricity.

Front

What type of bond is formed between two nonmetals?

Back

Covalent bond.

Front

What is the difference between polar and nonpolar covalent bonds?

Back

Polar covalent bonds have unequal sharing of electrons, while nonpolar covalent bonds have equal sharing.
