|
What is a Proton |
A stable subatomic particle in all atomic nuclei has a positive electric charge with an equal amount in magnitude to that of an electron. |
|
|
What is a Neutron |
A subatomic particle that has about the same mass as a proton but doesn't have an electric charge. |
|
|
What is an Electron |
A stable subatomic particle with a charge of negative electricity that is found in all atoms and acting as the main carrier for electricity in solids. |
|
|
What is an Atomic Mass |
It is equivalent to the number of protons and neutrons in the atom. |
|
|
What is an Atomic Number |
The number of protons in the nucleus of an atom, which shows what chemical element it is and shows its place in the periodic table. |
|
|
What is Alpha Radiation |
Ionizing radiation consisting of alpha particles, emitted by some substances undergoing radioactive decay. |
|
|
What is Beta Radiation |
High-energy electrons, carrying a negative charge, that are sent out by some radioactive nuclei. |
|
|
What is Gamma Radiation |
It is gamma rays. |
|
|
What is aIsotope |
Two or more forms of the same element that contain equal numbers of protons but have a different number of neutrons in their nuclei. |
|
|
What is Half-Life |
The time taken for the radioactivity of a specified isotope to fall to half its original value. |
