No, there are the same number of protons and electrons in an atom, but I don't think that they have the same mass.
You're right, an electron is 1,836 times lighter than a proton.
mass of an electron is 9.10939*10-31 kg
mass of a proton is1.67262*10-27 kg
1
(I use switched on schoolhouse- that is the answer)
The charge of a neutron is zero, and the mass number is one.
The charge of an electron is -1, and the mass, in proportion to a proton and a neutron is 1/1840 approx.
The proton has a positive charge and a mass number of 1.
A particle that has a mass of 1 and a charge of 1 plus is a proton.
Alpha particles are helium nuclei and consist of two protons and two neutrons. Their electric charge is +2 (+1 from each proton), and their mass number is 4, one for each proton and neutron. To describe their mass in other ways, it is 4.001506179125 atomic mass units, or 6.64465675 x 10-25 kg.
Proton number is decreased by two while mass number is decreased by four. Since alpha particle is similiar to helium nucleus.
not necessarily it has the smallest charge
The proton has much more mass than the electron, by a factor of 1836 times, a ratio called "mu". Recent astronomical research suggests mu may have changed by 20 parts per million in the last 12 billion years, but I plan to wait at least a billion years for confirmation!
The charge of a proton is positive 1 and the mass is approximately 1 atomic mass unit
To find the charge to mass ratio (specific charge) of an atom, you have to find both the charge of the nucleus and the mass of the nucleus charge of nucleus = proton number x charge of 1 proton (1.6x10^-19) mass of nucleus = nucleon number x mass of 1 proton (1.67x10^-27) the you have to divide the charge of the nucleus by he mass of nucleus e.g Q/M the answer should be in C/kg or Ckg^-1
Yes, the neutron has a negative charge and a mass that is smaller than the mass of a proton.
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.
The particle with one unit of positive charge is Proton. Answer Proton
Proton rest-mass . . . 1.67 x 10-27 kg Proton charge . . . . . +1 elementary charge (1.60 x 10-19 coul)
The two important characteristics of a neutron are its mass and charge. These are described below. 1) Mass of neutron. The mass of a neutron is equal to mass of a proton. The relative mass of neutron in 1 u. the absolute mass of a neutron is 1.6 * 10^-24 gram. 2) Charge of neutron. Neutron has no charge. It is electrically neutral. The two important characteristics of a Proton are its mass and charge. These are described below. 1) Mass of proton. The Proton is actually a hydrogen atom which has lost its electron. Since mass of an electron is very small, we can say that mass of proton is equal to mass of a hydrogen atom. The relative mass of neutron in 1 u. the absolute mass of a neutron is 1.6 * 10^-24 gram. 2) Charge of proton. The charge of a proton is equal and opposite to the charge of an electron. So absolute charge of a proton is 1.6*10^-19 coulomb.
The term nucleon is applied to any particle that makes up an atomic nucleus. That means it can be applied to either a proton or a neutron (but only when we are talking about them as the components of an atomic nucleus). The nucleon with the positive charge is the proton. You'll recall that the neutron is a neutral particle; it has no charge.
they have adout the same mass
The charge and mass ratio of proton is constant, the positive particles found during discharge tube experiment are nuclei of atoms which have different charge and mass ratio.
If you compare the mass of a positron to an electron, or of a proton to an anti-proton, and so forth, the mass is the same, even though the charge is reversed. Negative charge does not mean negative mass, it has no bearing on the mass.
No, that would be a neutron. A proton is a nuclear particle with a mass of 1 AMU and a 1+ charge
