This is the cluster of protons and neutrons (or just a proton) at the center of an atom.
What is the nucleus?
100
That guy just took my money! This type of bond is when electrons are stolen, not shared.
What is an ionic bond?
100
This is the measure of how difficult it is to break or stretch the surface of a liquid.
What is surface tension?
100
A chemical compound that releases H+ ions to a solution is this:
What is an acid?
200
This is substance that contains two or more elements in a fixed ratio.
What is a compound?
200
The number of protons determine which element is which, and is represented by this:
What is the atomic number?
200
This type of bond is when electrons are shared, not stolen. Kind of like communism. Or a symbiotic relationship.
What is a covalent bond?
200
Because of hydrogen bonding, water has a strong resistance to change in this.
What is temperature?
200
A chemical that accepts H+ ions and removes it from a solution is this.
What is a base?
300
Taking up about 65% of your bodily chemical composition, this element is the most common in the body.
What is oxygen?
300
This is the sum of the number of protons and neutrons.
What is the atomic mass?
300
This type of bond (not bomb) keeps a water molecule together.
What is a hydrogen bond?
300
Your cells are composed of this percentage of water.
What is 70-95%
300
This is a substance that resists pH change.
What is a buffer?
400
There are this many known elements that occur naturally on
Earth. That's how old your mom is.
What is 92?
400
These are alternate mass forms of an element. As some decay, they give off energy and are radioactive, radioactive (welcome to the new age, to the new age.)
What is an isotope?
400
These are charged atoms. How "ionic".
What is an ion?
400
As water evaporates from leaves, water is drawn up because of this property of water.
What is cohesion?
400
On the pH scale, urine is this.
What is acidic?
500
Four elements make up 96% of the human body. They are:
What are oxygen, carbon, hydrogen, and nitrogen?
500
The innermost shell can hold up to this number, and the outermost shell can hold up to this number.
What is two and eight, respectively.
500
Because of the "pull" of the oxygen in the nucleus on the hydrogen electrons, there is a shift in electric charge, giving water this property.
What is polarity?
500
Daily Double: Differentiate between a solvent and a solute
What is
a solvent is the dissolver
a solute is the dissolved substance.
