Describe the ligand field theory as applied to both octahedral and square planar transition metal complexes. discuss the trans effect and trans influence in relation to square planar complexes and rationalise the synthesis of cis- and trans-cl2pt(nh3)2.

its first and third is your answer i did the qustion the fourth isnt right

i think its 100

i hope this !

ca has a crystalline lattice with positive ions (since it is a metal, metals are positively charged) and electrons flow freely in its structure since the ca atoms have a large nuclear radius so the electrons are not tightly held, therefore the electrons can flow freely since they are not being highly attracted by the nucleus. moreover, one of the properties of metals are that they are conductors of electricity, thus proving ca is the element.
