GRHS Chemistry - Types of Bonds Test Review

Front

What is a covalent bond?

Back

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

Front

What type of bond is formed between beryllium (Be) and fluorine (F)?

Back

An ionic bond is formed between beryllium (Be) and fluorine (F).

Front

What is the charge of an oxygen atom with 8 protons and 10 electrons?

Back

The charge of the oxygen atom is O^2-.

Front

Which type of structure typically has a low melting point?

Back

Covalent structures typically have a low melting point.

Front

What type of bond exists between multiple zinc (Zn) atoms?

Back

Multiple zinc atoms are bonded together by metallic bonds.

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 between atoms.

Front

What are the characteristics of ionic compounds?

Back

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

Front

What are the characteristics of covalent compounds?

Back

Covalent compounds usually have lower melting and boiling points, may not be soluble in water, and do not conduct electricity.

Front

What is a metallic bond?

Back

A metallic bond is a type of chemical bond that occurs between metal atoms, characterized by a 'sea of electrons' that are free to move.

Front

How do you determine the type of bond formed between two elements?

Back

The type of bond can be determined by the difference in electronegativity between the two elements: a large difference indicates ionic, a small difference indicates covalent.
