Description : The most suitable unit for expressing nuclear radius is - (1) nanometre (2) fermi (3) angstrom (4) micron
Last Answer : (2) fermi Explanation: The atomic radius is a measure of the size of an atom. It is defined as one half the distance between the nuclei of two identical atoms that are bonded together. Angstrom is the most common unit used for measuring atomic radius.

Description : Ionisation energy of nitrogen is greater than that of oxygen because nitrogen has – (1) high bond dissociation energy (2) smaller atomic radius (3) stable half filled 2p sub level (4) high nuclear charge
Last Answer : (3) stable half filled 2p sub level Explanation: Ionization energy is a measure of the ease in which atoms lose electrons and become positive ions.

Description : If I calcuate "energy per m^3", do I express the unit for my answer as "J" or "J/m^3"?
Last Answer : You will need to express this as J/m^3 to be fully correct, but it seems the answers assume it is not necessary because the question states ‘per m^3’.
Description : When creating a Web document, which unit is used to express an image’s height and width? (a) Centimetres (b) Pixels -Technology
Last Answer : (b) Image’s height and width unit are expressed in pixels or in percent form.
Description : Why is the atomic mass unit rather then the gram usually used to express atomic mass?
Last Answer : Because a gram is too large a unit to express the mass of anatom. Also the Atomic Mass relates to what atoms or made of.If you convert the atomic mass into grams you have a mole of theelement.
