Chances of the alpha particle directly hitting the nucleus?
An alpha particle is a helium nucleus, and as such it has 2 protons and 2 neutrons and no electrons. Thus, it is positively charged. This makes it very unlikely that it will hit the nucleus which is also positively charged and will repel the alpha particle. The only way to get the alpha particle to hit the nucleus is to accelerate it to very high speeds.
Which particle or particles make up the nucleus?
Every nucleus (except for Hydrogen) consists of protons and neutrons. The hydrogen nucleus is only a proton.
Are neutrons found only in atoms?
No, neutrons are not only found in atoms. Neutrons are subatomic particles and can also exist independently in environments such as nuclear reactors or certain types of particle accelerators.
Where in the atom do you find each of the subatomic particles?
The only subatomic particle that has any role in chemistry is the electron.
Is the following true or false An alpha particle has a double charge because it is a helium atom that has lost two electrons?
True, it lost its only two electrons, which makes it consist of 2 protons and 2 neutrons
An atomic particle not in the nucleus is a?
Electrons are the only subatomic particles which are not part of the nucleus. The others, protons and neutrons, are.

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).
Are neutrons found only in atoms?
No, neutrons are not only found in atoms. Neutrons are subatomic particles and can also exist independently in environments such as nuclear reactors or certain types of particle accelerators.
Where in the atom do you find each of the subatomic particles?
The only subatomic particle that has any role in chemistry is the electron.
Which atom could not possibly emit an alpha particle?
Helium-4 cannot emit an alpha particle, as an alpha particle is composed of two protons and two neutrons. Helium-4 already has two protons and two neutrons in its nucleus, so it cannot emit an alpha particle.
What makes up the nucleus of the atom?
There are only two stable subatomic particles, Protons and Neutrons. Protons: Positive charge, 1amu The "atomic number" of an element gives the number of protons in its nucleus. Neutrons: No charge, makes up rest of the atomic mass, 1amu each The nucleus of every element contains one or more of each kind of stable subatomic particle, except for hydrogen which has ONE proton, but no neutrons
Is the following true or false An alpha particle has a double charge because it is a helium atom that has lost two electrons?
True, it lost its only two electrons, which makes it consist of 2 protons and 2 neutrons
What is the positively charged mass in the center of an atom?
This can refer to either the nucleus or to an individual proton that makes up the nucleus. Because only protons and neutrons occupy the nucleus, it has a positive charge.
What does the nucleus of an atom not contain?
The nucleus of an atom doesn't contain electrons, but it does contain protons and neutrons.
Which of the following subatomic particles are located in the nucleus of the atom?
The protons and the neutrons are located in the nucleus of an atom.
