Front

What is an Ionic Bond?

Back

An Ionic Bond involves the transfer of valence electrons between atoms, resulting in the formation of charged ions that attract each other.

Front

What is the name of Group 2 in the periodic table?

Back

Group 2 is known as the Alkaline Earth metals.

Front

What did Thomson experiment with?

Back

Thomson experimented with cathode rays, which led to the discovery of the electron.

Front

Is this a correct dot diagram for oxygen (O)?

Back

False. The correct dot diagram for oxygen should show 6 valence electrons.

Front

What is the electron configuration for Oxygen?

Back

The electron configuration for Oxygen is 1s2 2s2 2p4.

Front

What are Valence Electrons?

Back

Valence electrons are the electrons in the outermost shell of an atom that are involved in forming bonds.

Front

What is the difference between Ionic and Covalent Bonds?

Back

Ionic bonds involve the transfer of electrons, while covalent bonds involve the sharing of electrons between atoms.

Front

What are Alkali Metals?

Back

Alkali metals are the elements in Group 1 of the periodic table, known for being highly reactive and having one valence electron.

Front

What is a Dot Diagram?

Back

A dot diagram (or Lewis dot structure) represents the valence electrons of an atom as dots around the element's symbol.

Front

What is the significance of the Gold Foil Experiment?

Back

The Gold Foil Experiment, conducted by Rutherford, led to the discovery of the atomic nucleus.
