A hole is a place where an electron is missing. Since the electron has a negative charge, the lack of an electron produces a net positive charge.
The opposite of a negative charge is a positive charge. Positive charges have more protons than electrons, resulting in an overall positive charge.
No. Neutrons have a neutral charge. The nucleus is positive due to the presence of protons which have a positive charge.
Protons are associated with a positive charge.
Protons have a positive charge in atoms.
The test charge is positive in the experiment.
A black hole can have either positive, negative, or neutral charge. The charge of a black hole can be acquired through the consumption of charged particles, but the overall effect of the charge on the black hole's properties is not significant compared to its mass.
In a photocell, the charge of a hole is positive. Holes are essentially empty spaces in a crystal lattice where an electron has moved away, leaving behind a positive charge that can move through the material similar to a positively charged particle.
It might help to consider a hole as a positive particle (or rather, quasi-particle). Any positive particle gets attracted by a negative charge, and repelled by a positive charge. Of course, in reality it is the electrons that move, to fill out the hole - but the effect is the same.
A hole is a place where an electron is missing. Such places exist; and for practical purposes, it is convenient to think of them as independent positive charge carriers.
A proton has a positive charge.
A positive charge is a positive electrical charge. Particles with no charge are called neutral particles.
Protons are positive (each is +1) and electrons are negative (each is -1)
On their own metals have no charge. Metal ions have a positive charge.
Negative charge = electron Positive charge = positron Positive charge = proton
The proton carries a positive electrostatic charge. That charge is given as a +1 or can be expressed as 1.602 x 10-19 C.
A positive charge
A proton carries a positive charge of +1 elementary charge, which is equal in magnitude to the charge of an electron but opposite in sign. This charge is fundamental to the behavior of protons in interactions with other particles.
