LES 1 Flashcards
This has a negative charge and attracted to PROTONS
Electrons
Is the outermost shell of the atoms
Valence electrons
A mixture of metal and nonmental Ex: sILICONE, BORON, arsenic,
Metalloids
iS the presence or flow of electrons
Electricity
It freely moves electrons and a material in which electricity can easily flow
Conductors (Ex: copper, steel, gold, silver,)
This hold onto their electrons and can build a static and often used for safety purposes
Insulators (ex, wood, glass, rubber)
It collects charge but cannot flow
Static charge
River is to water molecules as wire is to
Electrons
rubbing the balloon hair causes the ballon to gain?
Electrons
True or false, electrons and protons have the same magnitude?
True
These are electrically neutral or have no charge
aTOMS
If an atom gains or loses electrons it gains a charge and become ???
An ion
Rubber objects almost always gain what type of charge
A negaative charge
A glass rod rubbed with silk will gain what type of charge
Positive
These are liquid solutions that can conduct electricity
Electrolytes
