What would be the benefit of knowing where the electrons are at any time?
Reactions that are classified as oxidation-reduction (redox) reactions all have the common trait that electrons leave one component (that is, getting oxidized) to be taken up by an
How many ion H2- does have The H2- ion having three electrons. This can be conceived as the combination of a hydrogen atom with a hydride ion (H-). By the aufbau principle, two
Electronic configuration of C is: (1) 1s 2 , 2s 2 , 2p 2 , (2) 1s 2 , 2s 2 , 2p 3 (3) 1s 2 , 2s 2 , (4) 1s 2 , 2s 2 , 2p 6
The energy of second Bohr orbit of the hydrogen atom is -328 kJ mol-1, hence the energy of fourth Bohr orbit would be: (1) - 41 kJ mol -1 (2) -1312 kJ mol -1 (3) -164
What are the examples of radiation hazards
Energy of orbit: (1) Increases as we move away from nucleus (2) Decreases as we move away from nucleus (3) Remains same as we move away from nucleus (4)None of the
For a reversible process involving ideal gases in a closed system, show that ΔS = C v ln(T2/T1) for a constant volume process ΔS = Cp ln(T2/T1) for a constant pressure proc
According to Bohr's principle, the relation between principle quantum number and radius of orbit is: (1) r ∞ n (2) r ∞ n 2 (3) ∞1/n (4) r∞ 1/ n 2 Ans: r
