This question can't be answered because you haven't said what the units are. You have just said 1.673 X 10-20 somethings. The mantissa of your number is strangely familiar. 1.673 X 10-27 Kg is the mass of the proton, which is a positively charged particle. This could also be put as 1.673 X 10-24 g or 1.673 X 10-21 mg. The exponent of 10-20 is the only thing stopping load cries of Eureka ! from here. You might like to check the number of zeros in your question.
It is called the nucleus and has a mass unit number of one.
It depends. If the decay contains a particle with mass, then the nucleus' mass number must decrease. If the decay involves the emission of a massless particle (like a gamma photon), then the mass number is unchanged. If the reaction (not technically a decay) involves the nucleus absorbing a particle with mass (like U-235 absorbing a neutron in a fission chain reaction) then it is a transmutation and not a natural decay. The mass number must increase.
In this context, we call an electron a beta particle.
When Rutherford put the gold foil in front of the alpha-particle emitting source, he noticed a few things: 1. Some of the alpha particles passed through the gold foil 2. Some the particles were deflected 3. Some of the particles bounced back Rutherford concluded that an atom is made up of mostly empty space and the actual size of the atom is far smaller than the space it occupies.
The short answer is no. Although matter is affected by electrostatic forces of attraction, no current is flowing and thus it does not fit the definition of electricity (a term for the variety of phenomena resulting from the presence and flow of electric charge).
The positively charged particle in an atom is the proton. The negatively charged particle is the electron. The electrically neutral particle is the neutron.
No, a proton is a positively-charged particle with a mass of 1.673 x 10-27 kg. What you described is a neutron.
Alpha is a particle not a wave. Alpha particle are positively charged helium nuclei and have a +2 charge and 4u mass.
the particle that is represent in the mass number is/ sum equals, protons and neutrons.
That particle is the proton.
Alpha particles are positively charged helium nuclei while beta particle are negatively charged electrons . Alpha particle have 4u mass while beta particles have zero mass.
Helium has 2 positively charged protons, 2 neutral neutrons and 2 negatively charged electrons.
Generally it is the Proton, but there is now evidence of a positron-or a positive electron. Same mass, just positively charged.
The mass and the charge. Protons are positively charged. Electrons are negatively charged. Neutrons have no charge. Protons and neutrons have similar mass (about 1 amu). The mass of electron is about 1822 times less than that of protons / neutrons.
Beta is a particle. In beta- it is an electron and an electron antineutrino. In beta+ it is a positron and an electron neutrino.
It is called the nucleus and has a mass unit number of one.
Proton rays consist of protons, a type of positively charged atomic particle, rather than photons, which have neither mass nor charge
