What are the particles in the atom that account for most of the mass of the atom are protons and electrons?
The particles in an atom that account for most of its mass are protons and neutrons, not electrons. Protons, which are positively charged, and neutrons, which have no charge, reside in the nucleus and contribute significantly to the atomic mass. Electrons are much lighter and orbit the nucleus, but their mass is negligible compared to that of protons and neutrons. Thus, the majority of an atom's mass comes from the nucleus.
What are the two principal components of the nucleus of the atom?
The two principal components of an atom at a subatomic level are Protons and Neutrons. Protons are subatomic particles with a mass of 1 and a charge of 1+ Neutrons are subatomic particles with a mass of 1 and a charge of 0 or neutral
Can charge exists without mass?
Charge can exist without mass in the form of electric fields and electromagnetic radiation. For instance, photons, which are massless particles, carry electromagnetic energy and can possess electric and magnetic fields. However, charged particles like electrons and protons do have mass. In summary, while charge itself can manifest in massless forms, charged particles inherently possess mass.
What particles make up the atomic mass number of an element?
The atomic mass number of an element is determined by mass of the nucleus of an atom. Therefore the particles that make up the nucleus determine the mass number. These particles are protons and neutrons.The mass of the protons and neutrons do not vary between elements, but the number of each in the nucleus varies between elements and between isotopes of the same element.
Which particles account for almost all the mass of an atom?
Protons and neutrons account for almost all the mass of an atom. Electrons have much less mass compared to protons and neutrons.
What are the particles emitted during radioactive decay with their mass and charge?
alpha: mass 4, charge +2beta: mass ~1/1800, charge -1gamma: mass 0, charge 0

What subatomic particles has appreciable mass and lacks a charge?
The neutron is the subatomic particle that has appreciable mass and lacks a charge.
What is the mass and electrical charge of alpha particles?
2.00 lbs the charge is alpha-magnetic
What are the features of the subatomic particles?
Subatomic particles have mass, dimensions, spin, sometimes have an electrical charge.
Alpha or beta types of radiation is composed of particles with a charge and mass identical to that of an electron?
Alpha radiation consists of particles with a charge of +2 and a mass of 4 amu, equivalent to a helium nucleus. Beta radiation consists of particles with a charge of either -1 or +1 and negligible mass, corresponding to electrons or positrons.
Smallest particles with very little mass and a positive charge?
proton
What elementary particles have a charge of -1 and mass that is almost zero?
Electrons.
Can charge exists without mass?
Charge can exist without mass in the form of electric fields and electromagnetic radiation. For instance, photons, which are massless particles, carry electromagnetic energy and can possess electric and magnetic fields. However, charged particles like electrons and protons do have mass. In summary, while charge itself can manifest in massless forms, charged particles inherently possess mass.
What is the mass and charge of alpha particles?
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.
Why is the charge to mass ratio of proton not constant?
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.
