The names "Bond"
100

The element that has 8 protons. 

What is Oxygen. 

100

The mass of an atom includes these two particles added together. 

What are protons and neutrons? 

100

Water is neutral and has a pH number of approximately ____. 

What is 7?

100

Water is a __________ which means it has a consistent ratio of 2 hydrogens to 1 Oxygen. 

What is a compound? 

100

The number of electrons needed to fill the valance or outer shell for most elements. (Exception Hydrogen, Helium and Lithium can be satisfied with only 2)

What is 8?
200

Most organic materials are made from non-metals that share electrons in pairs. These bonds can be single, ______, or even triple bonds. 

What are double bonds?

200

The number of protons equals the number of electrons in atoms without a charge. This is called a _________ atom. (hint starts with an "n")

What is neutral? 

200

pH of strong acids or bases can be harmful to body tissues. Which of the following chemicals could cause damage to cells and tissues? (list all) 

Bleach, Hydrochloric Acid (pH1) (stomach acid), Seawater, Cola, Oven Cleaner

What are Bleach, Hydrochloric Acid, and Oven Cleaner?

200

There are two types of bonds when working with more than one water molecule. This bond attracts water molecules together so that they "stick" and is also called cohesion. 

What is a hydrogen bond?

200

A metal such as Calcium will form this type of bond with a Non-metal such as Florine. 

What is ionic?
300

Hydrogen is more likely to form this type of bond because even though it is found with the metals, it is not actually a metal. 

What is covalent? 

300

Isotopes of Carbon are studied to determine the age of fossils. Isotopes are atoms of the same elements but have different amounts of the subatomic particles _________. 

What are neutrons? 

300
Excessive amounts of this chemical compound in the air can absorb into the ocean water and cause acidification. 

What is CO2 or Carbon Dioxide? 

300
The polarity of a water molecule comes from the charges created when Oxygen is greedy in its sharing of electrons. The resulting charge for hydrogen becomes this _____. 

What is positive? 

300

This element covalently bonds with other atoms of the same element to form large chains or rings. This is the basis of living organisms on earth.  

What is Carbon? 

400

All elements in the last column (Xenon, Neon, Helium) Have this trait in common. Because of this property, they do not chemically bond with other elements.

What is a full outside shell? (other answers similar accepted)
400

Elements called ________  __________ such as zinc, magnesium, and selenium are in very small quantities found in the body. These are very important for many biological functions including building tissues, immunity, and nutrient transport. 

What are trace elements? 

400
Adding a basic solution of pH8 to an acid solution with pH2 would cause the pH of the acid to become.... 

(would the pH go up or down from the original acid?)

What is rise? (would get closer to water pH7)
400
When water is in solid form it is different than most substances because it is (more/less) dense than in liquid form. 
What is less? 
400

Elements that give away electrons become _______ charged. These are called "cat-ions". 

What is positively? 

500

Carbon is so chemically versatile because it can form up to ____ different bonds with other atoms, including other carbons. 

What is 4? 
500

These 4 elements are the MOST abundant in the human body. 

What are Carbon, Hydrogen, Oxygen, and Nitrogen?  

500
When the pH surrounding a protein becomes too high or too low, the protein unravels and looses functionality. This is called ___________. (chapter 3 term)

What is Denaturation? 

500
A college in Oregon went out and got over 30,000 signatures to ban a substance called di-hydrogen monoxide. They truthfully explained that it can cause death, is responsible for property damage, and alarmingly explained all of the products that it can be found in. This substance has a common name. 

What is water? 

500

Some amino acids and water both form attraction bonds with other compounds because of their slightly positive charges. This is called what kind of a bond? 

What is a Hydrogen bond?
