Atomic structure

Orbitals

Orbitals

________ are areas where one is likely to find electrons at any point.

Ions

________ are charged and therefore can be accelerated by a electric field= acceleration.

RAM

________= average mass of an atom of an element, relative to 1 /12th of the mass of a carbon- 12 atom.

Quantum shells

________= the energy levels of an electron.

Particles

________ are detected by photographic methods= detection.

same energy level

When there are 2 or more orbitals in the ________, the fill up individually before being paired.

Periodicity

________= trends in element properties with increasing atomic number.

Pauli

________ exclusion principle= electrons in the same orbital must be in opposite spin.

Atoms

________ are bombarded with electrons from a charged gun and theyre ionised to form 1+ ions= ionisation.

Mass

________ number= number of protons and neutrons in the nucleus of an atom.

stick diagram

The output from a detector is presented as a(n) ________ and shows the mass to charge ration of the ions and the relative abundance.

Mass spectrometry

________ separates atoms and molecules according to their masses.

Aufbaus principle

________= as the atomic number increases, electrons are added from the lowest energy level (except from Cr, Cu)

Nuclear charge

________= total charge of all protons in the nucleus.

periodic table

The ________ is arranged in order of atomic number.
