Honors- Ionic/Covalent Compounds Weekly Assessment

Front

What is an ionic compound?

Back

An ionic compound is a chemical compound composed of ions held together by electrostatic forces termed ionic bonding. They typically form between metals and nonmetals.

Front

What is a covalent compound?

Back

A covalent compound is a chemical compound formed by the sharing of electrons between atoms, usually between nonmetals.

Front

What are the general properties of ionic compounds?

Back

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

Front

What are the general properties of covalent compounds?

Back

Covalent compounds typically have low melting and boiling points, low solubility in water, and do not conduct electricity.

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 happens to electrons in metallic bonding?

Back

In metallic bonding, electrons are shared among a lattice of metal atoms, creating a 'sea of electrons' that allows metals to conduct electricity.

Front

What is the electron configuration of metals?

Back

Metals typically lose electrons to achieve a stable electron configuration, often resembling the nearest noble gas.

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 is the formula for a covalent compound formed between sulfur and nitrogen?

Back

The formula is S4N4, indicating that four sulfur atoms are covalently bonded to four nitrogen atoms.

Front

What is the significance of electronegativity in bond formation?

Back

Electronegativity is a measure of an atom's ability to attract and hold onto electrons. It determines whether a bond will be ionic or covalent.
