Potassium carbon dating tagalog meaning

Its first four ionisation energies, 1086.5, 2352.6, 4620..7 k J/mol, are much higher than those of the heavier group 14 elements.The electronegativity of carbon is 2.5, significantly higher than the heavier group 14 elements (1.8–1.9), but close to most of the nearby nonmetals as well as some of the second- and third-row transition metals.

Thus, irrespective of its allotropic form, carbon remains solid at higher temperatures than the highest melting point metals such as tungsten or rhenium.

Carbon is known to form almost ten million different compounds, a large majority of all chemical compounds.

Graphite is much more reactive than diamond at standard conditions, despite being more thermodynamically stable, as its delocalised pi system is much more vulnerable to attack.

All carbon allotropes are solids under normal conditions, with graphite being the most thermodynamically stable form.

They are chemically resistant and require high temperature to react even with oxygen.
