Proton- positively charged subatomic particle that is found in the nucleus
Neutron- subatomic particle with no charge (neutral) that is found in the nucleus.
Electron- negatively charged subatomic particle that is found outside the nucleus, in the electron cloud.
The __electron_________________ is the smallest subatomic particle and is found __outside the nucleus, in the electron cloud_______.
The _proton_____ & ___neutron______ are the same mass.
The proton is found in the _nucleus__.
The neutron is found in the __nucleus__.
An atom having the same number of protons but a different number of neutrons is called an _isotope__.
The maximum # of electrons in the first energy level is__2___.
The maximum # of electrons in the second energy level is 8__.
The PT is arranged according to increasing atomic number.
The atomic # is the number of __protons_____ of an atom.
The __protons___ and the _electrons___ are the same.
Dot diagrams are used to show the _valence electrons available for bonding.
Normally, atoms are considered to be "neutral" because the number of _protons_ is equal to the number of _electrons__.
Dot diagram for Nitrogen and Neon. Practice doing a couple on your own.
Magnetism & Electricity:
Same (like) charges repel each other.
Opposite charges attract each other.
The area surrounding a magnet is the magnetic field.
Magnets are stronger at or toward the poles.
Electromagnets are made up of a power source, wire conducting current and an iron core.
Electricity- current (flow of electrons) flowing through a wire.
Series- current flows along 1 path; if one light bulb goes out, they all go out.
Parallel- current flows along more than one path; If one bulb goes out, the others stay on.
Convergent- where two plates come together; compression forces; form mountains and trenches
Divergent- where two plates pull apart; caused by tension forces; form mid ocean ridges and rift valleys
Transform- where two plates slip past each other; caused by shearing forces;…
