What is 16
The reason for water’s high boiling point
Hydrogen bonding
A molecule that has slight positive and negative charges due to an imbalance in the way electrons are shared.

Who was Rutherford
The number of valence electrons in a noble gas
What is 8
The cause of surface tension in water
What are hydrogen bonds Or cohesion?
Hydrogen bonding can lead to attraction between molecules of the same substance so that they stick together, which is called
What is cohesion
Atoms form bonds with other atoms because they want to complete
What is their outer shell
The family of elements that have a full outer shell, thus being stable and unlikely to form a chemical reaction, located in the far right column of the periodic table, are called.
What are the noble gases?
