Two atoms have the electron configurations 1s2 2s2 sp6 and 1s2 2s2 2p6 3s1. the first ionization energy of one is 2080 kj/mol and that of the other is 496 kj/mol match each ionization energy with one of the given electron configurations. justify your choice.

answer is: naturally occurring solid, inorganic compound or element is mineral.

minerals usually have crystalline form, that means than crystal constituents (atoms, molecules or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions.

for example magnetite is a mineral of iron oxide (fe₂o₃).

calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (caco₃).

dolomite is an   carbonate mineral composed of calcium magnesium carbonate (camg(co₃)₂).
