Explanation:

The atomic radius is taken as the half of the inter-nuclear distance between two covalently bonded atoms of non-metallic elements. It is also the half - distance between two nuclei in the solid state of metals.

Across a period on the periodic table, atomic radii decreases due to increase in the nuclear charge without an attendant increase in the number of electronic shells.

Down a group atomic radii increases due to successive shells of electrons being added.

a. Al or B : down a group III, so aluminium is larger

b. Na or AI : across a period so Na is larger

c. S or o : down group VI so sulfur is larger

d. O or F : across a period so oxygen is larger

e. Br or CI : down a group VII so Br is larger

f. Mg or Ca: down a group II so Ca is larger

Compare molecular & covalent network crystal solid?

Daniel [21]

Answer:

Molecular solids and covalent network solids are two types of solid compounds. The key difference between molecular solid and covalent network solid is that <em>molecular solid forms due to the action of Van der Waal forces </em>where as <em>covalent network solid forms due to the action of covalent chemical bonds.</em>
