depends on the polarity of the membrane
Negative charge = electron Positive charge = positron Positive charge = proton
negative
Net positive.
Yes - but really just the negative particles ... electrons.
A net postive charge
An electric charge is one of several properties which particles such as electrons and protons have. This particular property comes in two varieties - called "positive" and "negative". Particles which have the same charge - two positive particles, or two negative particles - repel one another; particles with different properties (one positive and one negative) attract one another.
Negative charge = electron Positive charge = positron Positive charge = proton
Two particles that have a charge of the same sign - that is, either two positive particles, or two negative particles.
Any "object" larger than elementary particles consists of positive and negative charges. If your object has a negative charge, it simply has more particles with a negative charge than particles with a positive charge.
negative
Proton - positive charge (+) Neutron - neutral charge (0) Electron - negative charge (-)
Net positive.
positive
These particles are: neutron (positive) and electron (negative).
Protons - Positive Electrical Charge Electrons - Negative Electrical Charge Neutrons - Neutral or No Charge
A negative charge attracts a positive charge and repels a negative charge. OPPOSITES ATTRACT ;)
For the particles in atoms: Neutron: Charge: neutral Electron: Charge: negative Proton: Charge: positive
