charge of proton/neutron
1.6 x 10^-19
SI unit for electric charges
coulomb (C)
each __ or ___ have the ___ ___ of charge
each proton or neutron have the same amount of charge
an atom contains __ number of protons and neutrons, thus it is __
an atom contains same number of protons and neutrons thus it is neutral
an atom is __ charged when it looses one or more electrons
an atom is positively charged when it looses one or more electrons
like charges
repel each other
an atom is __ charged when it gains one or more electrons
an atom is negatively charged when it gains one or more electrons
when two charged particles ar brought together, they produce
attractive or repulsive forces
unlike charges
attract each other
electric field
region in which an electric charge experiences an electric force
electric force
when a electric charged exerts a force on another nearby charge
draw the electric field around a positive charge
draw the electric field around a negative charge
draw the electric field of a pair of opposite charges
draw the electric field of a pair of positive charges
