What atomic particle can get rubbed off?
You think probable to electrons.
What is the only part of the atom that can be rubbed or pulled off?
Electrons
What does an alphaparticle give off?
An alpha particle is equivalent to a nucleus of the helium-4 atom.
When an unstable isotope gives off any kind of radioactive decay known as an alpha particle it is giving off?
It is giving off an Alpha particle. This is the nucleus of a helium atom, i.e. 2 protons and 2 neutrons (tightly bound together), without accompanying electrons.
The most massive particle in an atom is the?
The neutron has slightly more mass than a proton. Both are usually rounded off to a mass of 1 amu but the neutron is just a little heavier (about 1/1800 th heavier)
What atomic particle can get rubbed off?
You think probable to electrons.
What is the only part of the atom that can be rubbed or pulled off?
Electrons
When an atom gives off a(an)..... It becomes an atom with an atomic number of two less?
An alpha particle, which is the nucleus of a helium atom.
What is it called when a particle of an atom that flies off when a uranium atom is split?
Probably you think at fission products.
What does an alphaparticle give off?
An alpha particle is equivalent to a nucleus of the helium-4 atom.
What does ionising power mean?
Ionising power is the energy the particle has that is capable of 'knocking' electrons off an atom
Positively charged particle consisting of 2 protons and 2 neutrons which is given off by a radioactive substance is called what?
A radiation particle consisting of two protons and two neutrons is called an Alpha Particle. Alpha Particles have the same structure as a Helium nucleus. There are three forms of radiation, Alpha (Helium nucleus), Beta (a lone electron) and Gamma (an Electromagnetic wave).
What is the chemical equation for an atom of radioactive uranium giving off an alpha particle to become thalium?
92U238 --------> 90Th234 + 2He4
When an unstable isotope gives off any kind of radioactive decay known as an alpha particle it is giving off?
It is giving off an Alpha particle. This is the nucleus of a helium atom, i.e. 2 protons and 2 neutrons (tightly bound together), without accompanying electrons.
Is Al plus 3 an atom?
No, it's an ion or charged particle. It has a positive electric charge of 3. In other words, it's an aluminum atom with 3 electrons ripped off, thus leaving it with a full outer shell.
Which subatomic particles makes up most of the mass off the atom?
The major contribution to the mass of an atom is from protons and neutrons; electrons have a known but negligible mass.
When a polythene rod is rubbed with a duster it becomes negatively charged . why?
Because electrons are rubbed off the cloth and build up on the polythene.
