Ionic and Covalent Bonds

Front

What type of bond involves the sharing of electrons between atoms?

Back

Covalent Bond: A bond formed when two atoms share one or more pairs of electrons.

Front

In ionic bonds, metals tend to?

Back

Lose valence electrons: Metals lose electrons to achieve a full outer shell, forming positive ions.

Front

When metals bond with non-metals they form what type of bonds?

Back

Ionic Bonds: Formed when metals transfer electrons to non-metals.

Front

Sodium and Bromine will make a _____ bond.

Back

Ionic Bond: Sodium (a metal) loses an electron to Bromine (a non-metal), creating an ionic bond.

Front

MgO for a _____ Bond.

Back

Ionic Bond: Magnesium (Mg) loses two electrons to oxygen (O), forming MgO.

Front

What is an ionic bond?

Back

Ionic Bond: A chemical bond formed between two ions with opposite charges.

Front

What is a covalent bond?

Back

Covalent Bond: A bond formed when two atoms share electrons.

Front

What happens to electrons in ionic bonding?

Back

Electrons are transferred from one atom to another, resulting in the formation of ions.

Front

What is the charge of a sodium ion after it loses an electron?

Back

Positive Charge: Sodium becomes a Na+ ion after losing one electron.

Front

What is the charge of a bromide ion after it gains an electron?

Back

Negative Charge: Bromine becomes a Br- ion after gaining one electron.
