Glossary

GroupA vertical obelisk in the routine table. Members the a group generally have comparable properties and electron configurations in their external shell.

PeriodA horizontal heat in the regular table. The atomic number of each element increases through one, reading from left come right.

BlockElements are organised right into blocks by the orbital kind in i beg your pardon the outer electrons room found. These blocks are called for the characteristics spectra castle produce: sharp (s), primary (p), diffusive (d), and an essential (f).

Atomic numberThe number of protons in an atom.

Electron configurationThe arrangements of electrons above the critical (closed shell) noble gas.

Melting pointThe temperature in ~ which the solid-fluid phase adjust occurs.

Boiling point The temperature at which the liquid gas phase change occurs.

SublimationThe shift of a substance directly from the solid come the gas phase without passing through a liquid phase.

Density (g cm−3)Density is the mass of a substance that would certainly fill 1 cm3 at room temperature.

Relative atom massThe fixed of an atom loved one to the of carbon-12. This is around the amount of the number of protons and neutrons in the nucleus. Where much more than one isotope exists, the value offered is the abundance weight average.

IsotopesAtoms of the same aspect with different numbers that neutrons.
