which subatomic particle discovered last?

Only two types of quark are needed to form protons and neutrons, however, and these, together with the electron and one other elementary particle, are all the building blocks that are necessary to build the everyday world. The last particle required is an electrically neutral particle called the neutrino.

The proton was discovered by Ernest Rutherford in the early 1900's. During this period, his research resulted in a nuclear reaction which led to the first 'splitting' of the atom, where he discovered protons. He named his discovery “protons” based on the Greek word “protos” which means first.

Which statement describes the location of two types of subatomic particles in a helium atom? Protons and neutrons are located in the nucleus. Which term identifies the most probable location of an electron in the wave-mechanical model of the atom?

What subatomic particles (protons, neutrons or electrons) make up these solid lines? Electrons.

An electron is one of the most important types of subatomic particles. Electrons combine with protons and (usually) neutrons to make atoms. Electrons are much smaller than neutrons and protons. The mass of a single neutron or proton is more than 1,800 times greater than the mass of an electron.

Electrons are negatively charged and are the heaviest subatomic particle. Protons are positively charged and the lightest subatomic particle.

Protons, neutrons, and electrons are the three main subatomic particles found in an atom. The element Na has 11 protons, 11 electrons, and 12 neutrons for a total of 34 subatomic particles.

Subatomic particles include electrons, the negatively charged, almost massless particles that nevertheless account for most of the size of the atom, and they include the heavier building blocks of the small but very dense nucleus of the atom, the positively charged protons and the electrically neutral neutrons.

Summary. J.J. Thomson's experiments with cathode ray tubes showed that all atoms contain tiny negatively charged subatomic particles or electrons. Thomson proposed the plum pudding model of the atom, which had negatively-charged electrons embedded within a positively-charged "soup."

Proton. Electron is not found in the nucleus of an atom.

Electron, lightest stable subatomic particle known. It carries a negative charge of 1.602176634 × 10−19 coulomb, which is considered the basic unit of electric charge. The rest mass of the electron is 9.1093837015 × 10−31 kg, which is only 1/1,836the mass of a proton.

Subatomic particles are particles that are smaller than the atom. Protons, neutrons, and electrons are the three main subatomic particles found in an atom. Protons have a positive (+) charge. An easy way to remember this is to remember that both proton and positive start with the letter "P."
