1
Why should Chemistry be studied in A+P class?
 
Body functions depend on Cellular functions.
2
Anything that takes up space and has weight; composed of elements.
 
Matter
3
Composed of chemically identical atoms
 
Elements
4
These type of elements are required by the body in large amounts.
 
Bulk elements
5
These type of elements are required by the body in small amounts.
 
Trace elements
6
These types of elements are toxic to the body in large amounts
 
Ultratrace elements
7
Smallest particle of an element
 
Atoms
8
Part of an atom that carries a single positive charge
 
Proton
9
Part of an atom that carries no electrical charge
 
Neutron
10
Part of an atom that carries a single negative charge. They revolve around the nucleus.
 
Electron
11
Term for the number of protons n the nucleus of one atom and equals the number of electrons...
 
Atomic Number
12
The number of protons plus the number of neutrons of the atom.
 
Atomic Weight
13
Is it a different element if the number of protons change?
 
Yes
14
Is it a different element if the number of neutrons change?
 
No, but it becomes an isotope.
15
How do you find the neutron number?
 
Atomic weight minus the atomic number.
16
Atoms with the same atomic numbers but with different atomic weights are called?
 
Isotopes. They have the same number of protons and electrons but a different number of neutrons.
17
This type of radiation is composed of 2 protons and 2 neutrons.
 
Alpha radiation
18
This type of radiation is composed of fast moving electrons.
 
Beta Radiation
19
This type of radiation is composed of electromagnetic wave energy
 
Gamma radiation

26
An atom that gains or loses electrons to become stable and is an electrically charged atom.
 
Ion
27
A negatively charged ion that is formed when an atom gains electrons.
 
Anion
28
A positively charged ion formed when an atom loses electrons.

Hydrogen Bond
33
This is when chemical bonds form or break among atoms, ions, or molecules.
 
Chemical Reaction
34

This is the type of reaction when more complex chemical structures are formed. A+B = AB
 
Synthesis Reaction
37
This is the type of reaction when chemical bonds are broken to form simpler chemical structures....
 
Decomposition Reaction
38
This is the type of reaction when chemical bonds are broken and new bonds are formed. AB +...
 
Exchange Reaction
39
This is the type of reaction when the products can change back to the reactants. A + B AB
