Protons and neutrons have about the same mass, with the neutron being slightly more massive.
What else can I help you with?
Which subatomic particles are used to determine an atoms mass number?
Two particles are considered. they are protons and nrutrons
How do you do mass to particles?
By particles, I assume you mean atoms. Firstly, you divide mass by molecular mass to get moles. Then multiply moles by avagadros number to get amount of atoms
What subatomic particles responsible for most of an atoms mass?
These particles are the protons and neutrons.
Which two subatomic particles make up most of the atoms mass Where are they located?
These particle are neutrons and protons; they are located in the atomic nucleus.
What is interacting in a gravitational interaction?
Two particles are interacting in a gravitational interaction. It could be an two atoms, to electrons, or even to celestial bodies. The force of interaction between these two particles is directly proportional to its mass, and the constant of proportionality is the acceleration.
What are mass of unstable atoms?
The mass of unstable atoms can vary widely depending on the specific isotope and the decay process involved. Unstable atoms typically have a higher mass compared to stable atoms due to the presence of excess energy or additional subatomic particles. When unstable atoms undergo radioactive decay, they can transform into more stable elements by emitting particles and energy.
Do gases have a definite mass?
Yes, gases have mass because they consist of individual particles (atoms or molecules) that have their own mass. The mass of a gas is determined by the combined mass of its individual particles.
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.
What evidence supported thomsons hypothesis that the negative particles he observed from inside atoms?
Thomson had two pieces of evidence: 1- No matter what metal he used for the disk, the particles produced were indentical. 2- The particles had about 1/2000 the mass of a hydrogen, the lightest atom. These experiments provided the first evidence that atoms are made of even smaller particles.
Is a particle lighter than an atom?
Yes, many particles are lighter than atoms. Subatomic particles, such as electrons and neutrinos, have much smaller masses compared to atoms. For example, an electron has a mass of about 1/1836 that of a proton, which is a major component of atomic mass. Thus, several fundamental particles are indeed lighter than atoms.
What is the average mass of two atoms for beryllium?
The average mass of two atoms of beryllium is approximately 8.00 atomic mass units (amu).
Do nuetrons have higher mass or alpha particles?
alpha particles consist of two protons and two neutrons (helium nucleus) logically one neutron can not have a larger mass than two neutrons and two other subatomic particles of a similar mass
