Trends In Periodic Table And Radioactivity Flashcards
Atomic radius
Half the distance between the nuclei of the two atoms of the same element that are joined together by a single covalent bond
The first ionisation energy
The minimum energy required to completely remove the most loosely bound electron from a neutral gaseous atom in its ground state.
Second ionisation energy
The energy required to remove an electron from an ion with one positive charge in the gaseous state
Radioactivity
The spontaneous breaking up of unstable nuclei with the emission of one or more types of radiation
Nuclear reaction
A process that alters the composition, structure or energy of an atomic nucleus
Half-life
The time taken for half of the nuclei in any given sample of decay
Radioisotope
Radioactive isotope
Radiocarbon dating
A technique used to determine the age of an object containing carbon. It’s based on the ratio of carbon-14 to carbon-12 in the object.
