Electron and positron (anti-electron) have almost the same mass, with a negligible difference due to their opposite charge.

Are gas liquid and solid particles the same weight?

No, gas, liquid, and solid particles do not have the same weight. The weight of a particle is dependent on its mass, gravity acting upon it, and its volume. Gas particles have the least weight as they are highly spread out, while solid particles have higher weight due to their compact structure.


What charge particles would repel one another?

Two particles that have a charge of the same sign - that is, either two positive particles, or two negative particles.


What subatomic particles are almost the same weight?

Protons and neutrons are about the same weight. Electrons are far lighter than either protons or electrons.


Do two gases at the same temperature have the same kinetic energy?

Yes, two gases at the same temperature have the same average kinetic energy. Temperature is a measure of the average kinetic energy of the particles in a substance. Therefore, if two gases are at the same temperature, their particles have the same average kinetic energy.


What are the same number of these two particles in an atom?

Protons and electrons.


What two subatomic have about the same mass?

These particles are: proton and neutron.


What happens to an ice cubes particles when the ice cube is melting does the weight remains the same?

As the ice cube is solid , the particles are tightly packed together but as it melts it changes to a liquid so the particles change so that they are like particles in a liquid. the mass is conserved ( stays the same)


The atomic number is the same as the number of these two particles?

The "Atomic number" of an element corresponds to the number of only the protons in the nucleus of its atoms. Add to that the number of neutrons that are also in there, and you have the "Atomic weight".


The atomic number is the same as the number of what two particles?

protons and electrons


What two particles in an atom have approximatley the same mass?

Proton and neutron.


What happens when two of the same charged particles are near each other?

When two particles with the same charge are near each other, they will repel each other due to the like charges. The repulsion force is stronger the closer the particles are to each other. This repulsive force causes the particles to move away from each other.


Do alpha particles and helium atoms have same electrons?

No. The difference between them is that helium atoms have electrons, and alpha particles don't.
