A negative charge exists because of the electronegativity of oxygen.
there is a conservation of mass and charge.
Neutrons have no charge, but they do have mass.
The neutron has no charge, therefore the charge to mass ratio for the neutron is zero.
The charge of a proton is positive 1 and the mass is approximately 1 atomic mass unit
No such particle exists. All particles with charge also have mass -- no exceptions. Every particle with zero mass also has zero charge -- no exceptions.
Mass and charge are not connected. Negative charge is the charge carried by an electron.
Charge is of two types, mass is only of one kindThere are two types of forces (attraction and repulsion) between charges, but there is only one kind (attraction) between massesCharge is quantized, butquantization of mass is not established so farCharge has SI unitcoulomb , the SI unit of mass is kgCharge is conserved, but mass alone is not conserved (Mass + Energy is conserved)Charge cannot exist without a mass, but mass can exist without a net charge
Gravity exists because mass exists.
A negative charge exists because of the electronegativity of oxygen.
The charge has nothing to do with the mass, so there's no difficulty: A negative charge is one having the same sign as the charge on an electron. If you don't want electrons mentioned at all: A negative charge is one having the opposite sign as the charge on a proton.
2+ will be the charge in Ca2+ ion
all objects have mass, there is no such thing that exists that mass.
there is a conservation of mass and charge.
Neutrons have no charge, but they do have mass.
The neutron has no charge, therefore the charge to mass ratio for the neutron is zero.
Compared to the (charge/mass) ratio of the electron:-- The (charge/mass) ratio of the proton is much smaller; although the proton charge is equal to the electron charge, the proton mass is much larger, by a factor of more than 1,800.-- The (charge/mass) ratio of the neutron is zero, because the neutron charge is zero.
