He is sometimes called the discoverer of protons. He did experiments with cathode ray tubes, which knock electrons off atoms and attract them to a positively-charged electrode (the cathode). He noticed that a second stream of particles was attracted to the negatively-charged electrode (the anode), so he called them anode rays. However, it was left to one of his students to discover that these rays were sometimes pure protons. His experiments gave him a picture of atomic structure that was decades ahead of its time, and similar to what we know today. However, he did not follow up on his work, and was largely ignored by his peers.
the scientist behind the concept of the atom are joseph john thomson,goldstein, and james chadwick!
why are you searching it up? you should have known
In terms of atomic theory the protons and electroncs contribute the charge to an atom. In terms of quantum theory electrons are a type of lepton and protons are composed of quarks. So quarks and leptons contribute nuclear charge.
Protons have a positive charge and weigh 1 AMU Neutrons have a neutral charge and weigh 1 AMU Electrons have a negative charge and 1184 electrons weigh 1AMU so they are thought to add nothing to the mass of an atom. You may want to check out Bohr's model or the duet/octet rule.
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.
Eugen Goldstein is best known for his work in the field of atomic physics and his discovery of canal rays, which are positively charged particles. His findings contributed to the development of theories regarding the structure of the atom, particularly the existence of protons and the understanding of ionization processes. Goldstein's work laid the groundwork for later theories in atomic models, influencing the development of quantum mechanics and the understanding of atomic structure as it relates to chemical behavior.

what did marsden contribute to the evolution of the atom
we were feared of due to the technology of the atom bomb.

The subatomic particles that contribute most almost no weight to an atom are electrons at various energy levels. Isotopes of the same element differ from each other only by the number of neutrons.
A neutral particle in an atom is typically found in the nucleus, such as a neutron. Neutrons have no charge and contribute to the atomic mass of the atom.
The particles are protons, neutrons, and the nucleus inside of the atom Nice helping u >_<
This is the neutron.
Sir J.J Thomson first discovered that atoms had a negatively charged particle called an "ELECTRON". Afterwards , Goldstein discovered "PROTONS", the positively charged particles.
Hydrogen neutrons contribute to the stability and properties of an atom by helping to balance the positive charge of the protons in the nucleus. Neutrons also play a role in determining the mass of the atom and can affect its stability by influencing the nuclear forces within the nucleus.
