What subatomic particles make up an atom?
|
protons, nuetrons, electrons
|
|
|
List the charge, the mass in amu., and the location of the proton.
|
+1 charge,
1 mass in amu, located in the nuclues |
|
|
List the charge, the mass in amu., and the location of the nuetron.
|
0 charge,
1 mass in amu, Located in nucleus |
|
|
List the charge, the mass in amu., and the location of the electron.
|
-1 charge
0 mass in amu, Located in the orbitals outside of the nucleus |
|
|
What is the elemental stage?
|
The elemental stage always has a neutral charge because the number of protons is always equal to the number of electrons.
|
|
|
Why is electron configuration important?
|
Electron configuration is important because it determines how a particular atom will react with atoms of other elements.
|
|
|
When does the ground state occur?
|
The ground state occurs in an atom when electrons are found in the lowest available energy level.
|
|
|
When does an excited state occur?
|
An atom is in a excited state when an atom absorbs energy and electrons move to a higher energy level.
|
|
|
What is an isotope?
|
Istopes are atoms of one element that vary only in the number of nuetrons in the nucleus.
|
|
|
What is a radioactive isotope?
|
A radioactive isotope is one in which the nucleus decays spontaneously, giving off particles and energy.
