(a)
Interpretation:
The given set of elements has to be arranged in increasing order of atomic radius.
Concept Introduction:
The atomic radius of a chemical element is a measure of the size of its atoms, the atomic radius is distance from the centre of the nucleus to the boundary of the surrounding cloud of electrons.
The atomic radius decreases from left side to right side in the periodic table whereas atomic radius increases from top to bottom in the periodic table.
(b)
Interpretation:
The increasing atomic radius of the element should be identified.

- What enables a radioisotope to substitute for an ordinary (nonradioactive) atom of the same element molecule?arrow_forwardThe triple point of an element is at 75 torr and 125°C. This means that liquid is more dense than solid cannot exist at 1 atmosphere pressure cannot have a vapor pressure less than 75 torr cannot exist above 125 degrees Celsius What is the electron geometry (or electron arrangement) around an atom in a molecule or ion which is surrounded by three lone pairs of electrons and two single bonds T-shaped see-saw trigonal planar trigonal bipyramidal linear A red blood cell placed in pure water will swell because water moves from a higer osmotic pressure to a lower osmotic pressure the osmotic pressure is greater in the cell than in the water the osmotic pressure is the same in the cell and the water the somotic pressure is greater in the water than in the cellarrow_forwardWhich of the following substances will have the greatest lattice energy?
