Interpretation:
The sixth period
Concept Introduction:
Atomic radius: The concept explain chemical element is a measured of the size of its atoms, in other words to measure the distance from the center of the nucleus to the boundary of the surrounding cloud of number of electrons.
Density properties of transition metals: Generally the transition metals possess a high density, high melting points and high boiling points. These properties are due to metallic bonding by delocalized (d-electrons) and leading to cohesion which increases with the number of shared electrons.

- Atomic radius is usually inferred from crystallographic data on elemental solids and is a crude measure of the size of the electron cloud around the nucleus. The data below are atomic radii for the elements in the second row of the Periodic Table. Explain the trend. Li : 0.152 nm Be: 0.113 nm B: 0.088 nm C: 0.077 nm N: 0.075 nm O: 0.066 nm F: 0.058 nmarrow_forwardWhich statement is true about an element with the generic valence electron configuration ns²np4? This element is diamagnetic. The ion of this element would be isoelectronic with the noble gas in the preceding period. It has a lower ionization energy than an element with the generic electron configuration ns² when 'n' is the same number. It has a higher electron affinity than an element with the generic electron configuration ns²np² when 'n' is the same number. The element's ionic radius would be smaller than its atomic radius.arrow_forward5arrow_forward
