Composition of Water
The reason water is attracted to other molecules that contain a full charge, like an ion, or a partial charge
What is a polar molecule or what is polarity?
A liquid substance capable of dissolving other substances.
What is a solvent?
Atoms form bonds with other atoms because they want to complete
What is their outer shell.
What are the 2 parts of an atom that have opposite charges?
What are protons and electrons
The substance type that does not dissolve in water.
What is nonpolar?
A substance dissolves in water but not in vegetable oil. What is one of the two kinds of substances that it could be?
What are polar and/or ionic
When an ionic compound is dissolved in water, what does the compound break into?
What are ions?
The charge of an electron is
What is negative
The attraction between the polar sides of water, forming a strong bond in water.
What is hydrogen bonding?
The "stickiness" of water, causing it to be able to climb a vertical surface, is called
What is a adhesion?
A substance that is dissolved in a solvent.
What is a solute?
A molecule that has slight positive and negative charges due to an imbalance in the way electrons are shared.
What is polar?
The protons are located in the
What is the nucleus?
The positive side of the H20 molecule.
What is hydrogen?
The phenomena that occurs when individual molecules are so strongly attracted to each other that they tend to stay together, even when exposed to tension.
What is cohesion?
True or False: Non polar liquids will not dissolve ionic or polar substances.
What is TRUE?
If an atom has 6 electrons on it's outer shell, how many opportunities does it have to form a chemical bond?
What is 2?
Silicon's Atomic number is 14. How many electrons does it have in it's outer shell?
What is 4?
The cause of surface tension in water.
What is cohesion and/or what is hydrogen bonds?
The property of the surface of a liquid that allows it to resist an external force, such as a lizard running on it, due to the cohesive nature of its molecules.
What is surface tension?
The type of liquid that will dissolve a nonpolar substance.
What is nonpolar?

How many atoms are in one molecule of C12H22O11
What is 45?
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?
