PLEASE HELP I AM FAILING SCIENCE Which element is the group 1 element with the highest ionization energy?

A. Li

B. Si

C. K

D. Ca

E. Fr

I already answered it once and I got it wrong. I chose Si.

The answer is Li.

Explanation: Second ionization energy is much greater than the first ionization energy for each element.

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).

i don,t know so just answer mine
