Question

what is the maximum number of electrons that can be accommodated in a shell?Write the formula

Answer 1

Each shell can contain only a fixed number of electrons: The first shell can hold up to two electrons, the second shell can hold up to eight (2 + 6) electrons, the third shell can hold up to 18 (2 + 6 + 10) and so on. The general formula is that the nth shell can in principle hold up to 2(n2) electrons.

Answer 2

1. the formula used to determine the maximum number of electrons 2n^{2} [/tex] where n stands for number of shell.

2.Basic criteria to be followed to measure biodiversity are .

*Total number of entities including the number of individuals, the number of species and the number of different habitats are taken into consideration.

*The dissimilarities between the entities are also taken into consideration.

*Indicator species are also used to measure biodiversity

3.ethonol gets oxidised to ethanal with cromic anhydride dissolve in ethanolic acid

CH3CH2CO------>CH3CHO

Ethonol gets oxidised to ethanolic acid with pottasium permagnate

CH3CH2CO------>CH3COOH

Mg2+ and O2- ions are isoelectronic. However, magnesium has a greater number of protons than oxygen, and hence greater effective nuclear charge and larger force of attraction with the valence electrons
