Helium.
Used by Rutherford in his experiment made of two protons and two neutrons are alpha particles. Rutherford discovered the nucleus using his gold foil experiment.
An alpha particle consists of two protons and two neutrons.
it consists of two protons and two neutrons
An alpha particle is composed of two protons and two neutrons.
Protons and Neutrons
2 protons and 2 neutrons. An alpha particle is the same as a helium nucleus.
A nucleon is the amount of protons and neutrons. An alpha particle has an atomic number of 2 and a atomic mass of 4 then it has 2 protons and 2 neutrons.There are 4 nucleons in an alpha particle.
Alpha radiation is made up of alpha particles, which are helium nuclei consisting of two protons and two neutrons. These particles have a positive charge and are relatively large and heavy compared to other types of radiation.
An alpha particle is made up of two protons and two neutrons; this is what a helium nucleus is made up of as well.
An ALPHA particle may be thought of a a helium nucleus. It contains two protons and two neutrons. An alpha particle is a high speed helium nucleus (He^(2+)).
