Answer #1

The increasing order of first Ionization enyhalpy of 3rd period elements

Group 1 2 3 4 5 6 7 8  

Na < Mg > Al < Si < P > S < Cl < Ar

In 3rd period, element with highest ionization enthalpy is argon due to stable octet cofiguration.

Case1. Mg > Al

Due to stable ns2 configuration of Mg

Case2. P > S

phosphorous has half filled p subshell in its valency shell that gives extra stability and hence more energy is required to remove an electron.

Consider the first three energy levels of hydrogen (n = 1, 2, 3). a) What photon energies can be observed from transitions between these levels? Label these in increasing order as E1, E2, and E3. b) A hydrogen atom which is initially in the n = 2 level collides with an aluminum atom in its ground state (the kinetic energy of the collision is nearly zero). The hydrogen can drop to the n = 1 level and ionize the aluminum...

A oscillating wave-energy-converter (WEC) can be modelled as a mass-spring system forced by sinusoidal waves. A simple model would be given by the following DE: x''(t) + x'(t) + Kx(t) = h sin(ωt), where x measures the position of the WEC; K is a tuning parameter, chosen so that the WEC resonates with the waves; h is the height of the waves; and ω is the frequency of the waves. (a) Find a particular solution for the model. (b) Using...

You have $10,000 that you can deposit in any of three savings accounts for a 3- year period. Bank A compounds interest on an annual basis, Bank B compounds interest twice a year, and Bank C compounds interest on a monthly basis. All three banks have a stated annual interest rate of 4%. Calculate the amount that you would have at the end of the third year, leaving all interest paid on deposit, in each bank. On the basis of...

Energy in Resonant Circuits: Consider how the energy flows around different components of a circuit at resonance. General Role of Circuit Components: In general, where is energy input into the circuit? Where is energy taken out of the circuit? Where is energy stored in the circuit? Analyzing Power through Components: To see how the energy flows between different components, we should understand what the power is through various components at different times. Consider a resonant circuit with (for simplicity) L=R=C=V0=1...
