A molecule that is polar: -can form a hydrogen bond. -has an unequal charge
Electrolytes are: called cations if they have a negative charge.
As the concentration of hydrogen ions increases, the pH goes _______, and the solution becomes more _________. down; acidic
A force holding two atoms together is a(n) chemical bond.
Hydrolysis _____ a water molecule. breaks down compounds by adding.
Ionic bonds are chemical bonds formed by the: transfer of electrons from one atom to another.
What term is used to describe all of the chemical reactions that occur in body cells? metabolism
Chemical bonds formed by the sharing of electrons are called covalent.
Which subatomic particles carry a charge? Protons and electrons
As the concentration of hydroxide (OH-) increases, the - solution becomes more basic - pH rises
An atom can be described as chemically inert if its outermost electron shell contains _________ electrons. eight
The reaction between hydrogen and oxygen needed to form water is an example of a: synthesis reaction.
The total number of electrons in a neutral atom equals the number of protons in its nucleus.
An element that contains the same number of protons but different numbers of neutrons is called a(n) isotope.
A substance that cannot be broken down or decomposed into two or more different substances is called a(n) element.
As a result of which reaction during catabolism is a water molecule added to break a larger compound into smaller subunits? hydrolysis
Which type of chemical reaction results in the breakdown of a complex substance into two or more simpler substances? decomposition reaction
A chemical bond formed by the sharing of one or more pairs of electrons between the outer shells of atoms is called a(n) ___________ bond. covalent
The most abundant element essential to life is carbon.
The type of chemical reaction most likely to require energy is a(n) __________ reaction. synthesis
The element oxygen has an atomic number of 8, which means it contains: eight protons.
Acids, bases, and salts belong to a large group of compounds called electrolytes.
The elements carbon, hydrogen, oxygen, and nitrogen make up which percentage of the human body? 96%
The atomic number tells you the number of protons in the nucleus.
The water molecule has two distinct ends, each with a partial electrical charge. Because of this structure, water is said to be polar.
Atoms with fewer than eight electrons in the outer energy level will attempt to lose, gain, or share electrons with other atoms to achieve stability. This tendency is called the octet rule.
Acids release hydrogen ions.
Hydrogen bonds result from unequal charge distribution on a molecule. Such molecules are said to be polar.
A weak acid: dissociates very little in solution.
For sodium to transform from a neutral atom to a positive ion, it must: lose an electron.
A weak acid: dissociates very little in solution.
For sodium to transform from a neutral atom to a positive ion, it must: lose an electron.
Which of the following is not a subatomic particle? Radon
Atomic mass is determined by the number of: protons and neutrons.
Which of the following bonds are the weakest? Hydrogen
A magnesium atom has an atomic number of 12, an atomic mass of 25, and a +2 charge. This atom would contain _______ protons, _______ neutrons, and _______ electrons. 12; 13: 10
The hydrogen isotope tritium consists of: one proton and two neurons.
The study of metabolism includes examination of: - catabolism - anabolism - ATP requirements
Which of the following is not one of the major elements present in the human body? Zinc
The type of reaction in which substances are combined to form more complex substances is called a(n) ________ reaction. synthesis
An example of a catabolic process is: hydrolysis
The approximate pH of gastric fluid is: 2.
Acids - are proton donors - taste sour - release hydrogen ions in an aqueous solution.

In the presence of a base, red litmus paper will turn blue.
The atomic number of carbon is 6. How many unpaired electrons are in its outer shell? Four
The formation of sucrose involves the removal of a molecule of water. This is called dehydration synthesis.
Carbon has an atomic number of 6. The number of electrons found in the first shell is two.
The octet rule refers to the stability of the atom when there are eight electrons in the outermost energy level.
When atoms combine, they may gain, lose, or share electrons.
An example of an element would be Ne.
A solution that contains a greater concentration of hydroxide ions (OH-) than hydrogen ions (H+)is a(n) ________ solution. alkaline (basic).
Substance that accept hydrogen ions are called bases.
As the concentration of hydrogen ions (H+) increases, the solution becomes more acidic.
Which of the following represents properties of water? - High specific heat - High heat of vaporization - Strong polarity
An isotope of an element contains different numbers of ______ from other atoms of the same element. neutrons
