allotrope Some elements exist in several various structural forms, called allotropes. Each allotrop has different physical properties.

|Discovery day||identified as an element in 1746, yet known to the Greeks and also Romans prior to 20BC.|
|uncovered by||Andreas Marggraf|
|beginning of the name||The surname is obtained from the German, "zinc", i m sorry may in turn be obtained from the Persian native "sing", meaning stone.|
GroupA vertical pillar in the periodic table. Members that a group commonly have similar properties and electron configuration in their outer shell.
PeriodA horizontal heat in the regular table. The atomic number of each element increases through one, analysis from left come right.
BlockElements are organised right into blocks by the orbital kind in i m sorry the outer electrons space found. This blocks are named for the properties spectra castle produce: sharp (s), principal (p), diffuse (d), and fundamental (f).
Atomic numberThe variety of protons in an atom.
Electron configurationThe species of electrons above the last (closed shell) noble gas.
Melting pointThe temperature at which the solid liquid phase adjust occurs.
Boiling point The temperature at which the liquid gas phase adjust occurs.
SublimationThe change of a substance straight from the solid to the gas phase without passing with a liquid phase.
Density (g cm−3)Density is the mass of a substance that would certainly fill 1 cm3 in ~ room temperature.
Relative atom massThe massive of one atom family member to that of carbon-12. This is approximately the amount of the variety of protons and neutrons in the nucleus. Where more than one isotope exists, the value given is the abundance weighted average.
IsotopesAtoms the the same element with different numbers that neutrons.
