A datasheet is a useful way of viewing data in Access. Most importantly, datasheet view allows a user to view many table records at the same time. In datasheet view, information is displayed in rows and columns—similar to a spreadsheet. Records are displayed as rows, so each row is an individual record.

बेबि बीच 4 years, 10 months ago (3432723)

Let a ray from medium 1 (rarer) to enter medium 2(denser) such that refractive index occurs, now, Using snell's law, n1 sin i = n2 sin r where i is angle lf incidence and r is angle of refraction. Now since total internal reflection is occuring here, angle r = 90° Using this in snells law we get, n1 sin i = n2 ic = critical angle (ic) here, sin ic=(n2/n1) since n(refractive index) = speed of ray in vaccum / speed in medium, Therefore, sin ic= (c/v1)/(c/v2) = v2/v1 Therefore critical angle = v2/v1

The valency can be calcualted by electronic configuration- 1s²,2s²,2p⁶, 3s²,3p⁶,4s²,3d¹⁰,,..... For ex ample in the case of oxygen it has atomic no.-8, So from the above formula(electronic configuration) Oxygen-8(atomic no.) 1s²,2s²,2p⁴ 2,2+4=2,6 Thus ,no. Of eletrons in the last shell is called valency so, 6 is valency

The maximum no. Of electrons an element can either gain, loose or share as per its energy is called valence. Molecular mass is simple. It is the mass(atomic mass) of all the molecules of an element .

Naman Singh 4 years, 11 months ago (10282377)

Given the valence of two elements, find the least common multiple of the absolute value of the valence. Then divide the least common multiple by the absolute value of the valence to find the number of atoms in the molecule. (2) The oxygen element usually shows -2 valence.29-Jan-2020
