Why should Chemistry be studied in A+P class?
|
Body functions depend on Cellular functions.
|
Anything that takes up space and has weight; composed of elements.
|
Matter
|
Composed of chemically identical atoms
|
Elements
|
These type of elements are required by the body in large amounts.
|
Bulk elements
|
These type of elements are required by the body in small amounts.
|
Trace elements
|
These types of elements are toxic to the body in large amounts
|
Ultratrace elements
|
Smallest particle of an element
|
Atoms
|
Part of an atom that carries a single positive charge
|
Proton
|
Part of an atom that carries no electrical charge
|
Neutron
|
Part of an atom that carries a single negative charge. They revolve around the nucleus.
|
Electron
|
Term for the number of protons n the nucleus of one atom and equals the number of electrons in the atom.
|
Atomic Number
|
The number of protons plus the number of neutrons of the atom.
|
Atomic Weight
|
Is it a different element if the number of protons change?
|
Yes
|
Is it a different element if the number of neutrons change?
|
No, but it becomes an isotope.
|
How do you find the neutron number?
|
Atomic weight minus the atomic number.
