What else can I help you with?
What is a radioactive particle that is made up of two protons and two neutron?
This is a alpha particle.
Why is an alpha particle sometimes referred to as a helium nucleus?
An alpha particle is made up of two protons and two neutrons; this is what a helium nucleus is made up of as well.
What is a radioactive particle that is made up of two neutrons and two protons?
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.
What two things are a alpha particle made up of?
Protons and Neutrons
Which naturally occurring radioactive particle is the largest?
Alpha particles are the same size as a helium nucleus and are made up of 2 protons and two neutrons. They have no electrons so an alpha particle has a +2 charge
What is made up of 2 protons and 2 neutrons?
In terms of radioactivity it is an alpha particle.
How do the mass and size of an alpha particle compare with mass and size of beta particle?
The mass and size of an alpha particle compare with the masa and size of beta particle in the sense that the alpha particle is significantly larger in both size and mass that the beta and gamma particles. This is why it is called the alpha particle.
Which has the largest mass alpha particle gamma ray positron or beta particle?
The alpha particle is much more massive than a beta particle. A beta particle is an electron, which has very little mass. An alpha particle is a helium nucleus, and consists of two protons and two neutrons.
What is a alpha particle made of?
+ve charges
Why is an alpha particle attracted to a negative plate?
An alpha particle is made up of two protons and two neutrons, giving it a positive charge. As opposite charges attract, the positive charge of the alpha particle is attracted to the negative charge of the plate.
Who said atoms were made up of subatomic particles?
Rutherford proved it it from his alpha-particle scattering experiment.
How massive is a alpha particle?
an alpha particle is made of two protons and 2 neutrons. its basically the same as the nucleus of a helium atom
