Synthetic
Group 1 of the periodic table.
Noble
Gases
Group 8 of the periodic table,
low reactivity.
Atomic
Mass
Relative Atomic Mass: The mass of
one atom of an element compared
with one-twelfth of the mass of one
atom of carbon-12.
Mendeleev
Dmitri Mendeleev is generally noted as
the creator of the modern periodic table.
His theory was to leave room for
elements not yet discovered.
Atomic
Number
The number of protons (and therefore
of electrons) in an atom.
Orbital
The region in an atom where an
electron is most likely to be found.
Atom
A single unit of an element.
Halogens
Group 7 of the periodic table.
Block
The periodic table is split up into four
blocks, s, d, p and f, based on the
element’s characteristic orbital.
Period
A horizontal row of the periodic table.
Electron
A negatively charged particle.
Electrons orbit the atomic nucleus in
energy levels.
Neutron
A neutral (uncharged) particle in the
atomic nucleus. Its mass is
approximately 1 atomic unit.
Element
A substance which cannot be broken
down into any simpler substance by
chemical means.
Proton
A positively charged particle in the
atomic nucleus. Its mass is
approximately 1 atomic unit.
The elements in a column of the
Periodic Table.
Synthetic
An element too unstable to occur
naturally on Earth.
