Electron was the first subparticle discovered because it has a negative charge .later protons where discovered because using the foil method determined the protons existence .But because the neutrons are neutral and uncharged they where the last to be dicovered even though they take up almost all the mass of an atom
What else can I help you with?
When a neutron decays what does it form?
Outside the nucleus, free neutrons are unstable and have a mean lifetime of 885.7±0.8 s (about 15 minutes), decaying by emission of a negative electron and antineutrino to become a proton: : n0 → p+ + e− + νe
What is the positivley charged particle in the nucleus of and atom?
The positively charged particle in the nucleus of an atom is the proton.
What are the names of three particles in an atom?
The 3 Particles in a atom are * Proton * Neutron * Electron
What series lists particles in order from the smallest to greatest mass?
Electron, proton, nucleus, atom
Who discovered the subatomic particles and in which order?
Electron: J. J. Thomson, 1897 Proton: Ernest Rutherford, 1919 Neutron: James Chadwick, 1932
What is a proton in the nucleus converted into what during electron capture?
During electron capture, an electron and proton combine and are converted to a neutron.
What is the lightest proton neutron electron or nucleus?
Electron is the lightest.
What subatomic particles is neutral nucleus proton neutron electron?
neutron
What heappens to an atom that experiences radioactive decay?
Electron capture is the absorption of an electron by an atomic nucleus if that nucleus is neutron poor. An electron is captured, usually from an inner electron shell of that atom, and it will convert a proton in the nucleus into a neutron. We know that a neutron is converted into a proton and an electron in neutron decay, so it might be looked at as something of an opposite nuclear reaction where a proton and an electron combine to form a neutron.
What is an atom name that is made of a proton a neutron and an electron?
It is the atom of deuterium. Its nucleus is composed of a proton and one neutron. The atom has one electron that is orbiting around the nucleus.
who particle has greatest mass electron proton neutron or hydrogen nucleus?
hydrgen nucleus
In a beta particle emission what does the neutron split into?
In beta particle emission, a neutron in the nucleus converts into a proton, an electron (beta particle), and an antineutrino.
How neutron transforms into proton and electron?
A neutron can transform into a proton, an electron, and an antineutrino through a process called beta decay. During beta decay, a neutron in the nucleus of an atom is converted into a proton, an electron (beta particle), and an antineutrino. This process helps maintain the balance of protons and neutrons in the nucleus.
What is the organization of atoms?
It is proton neutron in the nucleus and then electrons in the electron cloud.
What part of the atom carries no electric charge?
There are three primary subatomic particles: the neutron, the electron and the proton. The electron is negatively charged, the proton is positively charged and the neutron has no charge.
A proton neutron and electron are in the nucleus of an atom?
yes they are what makes up the atom
Which particle is not found in the nucleus?
Atoms are the building blocks of matter. Atoms are made up of electron, neutron and proton particles. Electrons are negatively charged, neutrons are neutral and protons have a positive charge.
