refers tothe repeated pattern of similar chemical properties as elements are arranged in order of increasing atomic number. Elements with similar chemical properties are placed in the same group on the periodic table.
these contain elements with similar outer-shell electronic configurations. For instance, atoms of the alkali metals in the first group have a half-filled s-orbital (s1) in their outer shell.
these are numbered 1-7 and each contain elements with electrons in the same outer shell. The number of the period is the same as the number of the outer shell.
contains transition metals, and is located between the s- and p-blocks. It contains elements in which the five orbitals (with a maximum of 10 electrons) of the d-shell are progressively being filled.
contains the lanthanides and actinides. The seven orbitals are able to contain a maximum of 14 electrons.
the tendency of an atom or radical to attract electrons in the formation of an ionic bond
The minimum amount of energy that is required to remove an electron from an atom or ion, in the gaseous state
elements on the right side of the periodic table. , elements that are usually dull in appearance, poor conductors of heat and electricity, gases at room temperature
left of the zigzag line, shiny, malleable, ductile, good conductors of electric current, good conductors of thermal energy
some elements, such as germanium, silicon, arsenic and tellerium are located across periods and display both mettallic and non-metallic properties. These are called...
the elements of group 18, including helium, neon, argon, krypton and xenon. They are unreactive, due to the outer-shell electron configuration of s2p6, a stable arrangement.
