The periodic table was arranged so that properties could be predicted for elements, just by looking at their position in relation to other elements. consider two of the group 2 elements, magnesium and strontium. which statement accurately describes the difference in the atomic radius? magnesium has a larger atomic radius because it has a lesser effective nuclear charge. strontium has a larger atomic radius because it contains more protons. magnesium has a smaller atomic radius because it has 2 valence electrons. strontium has a larger atomic radius because strontium has more shells of electrons than magnesium does.

The human eye contains a molecule called 11-cis-retinal that changes shape when struck with light of sufficient energy. the change in shape triggers a series of events that results in an electrical signal being sent to the brain that results in vision. the minimum energy required to change the conformation of 11-cis-retinal within the eye is about 164 kj/mol.
