1st-year Chemistry Chapter 5 Notes pdf Short Questions
01. Why is it essential to lower the strain withinside the discharge tube to get the cathode rays?
By reducing the strain withinside the discharge tube the no. of fueloline molecules is additionally, reduce. Due to much less no. of substances, the quandary within the motion of electron particles is additionally reduced. So, cathode rays are the most effective products at low strain.
02. Whichever fueloline is used withinside the discharge tube the character of cathode rays is identical. Why?
Cathode rays are essentially electrons. Electrons are the essential particle of count number. Every counting number has an electron of equal nature. Then, cathode rays have an identical natural nature for each fuel line.
03. Why the e/m cost of the cathode rays is simply identical to that of electrons?
The e/m cost of the cathode rays is simply identical to that of electrons due to the fact cathode rays are clearly electrons i. e. 1.7588 × 1011C kg−.
04. How the bending of cathode rays withinside the electrically and magnetic discipline suggests that they may be electrons?
In the magnetic discipline, cathode rays are deflected perpendicular to the road becoming a member of the 2 poles of the magnetic discipline.
In the electric discipline, those rays deflected toward a fantastic plate which suggests that they have a terrible price on them.
05. Why fantastic rays also are known as canal rays?
Small openings whole withinside the cathode are known as canals. Positive rays skip thru those canals and bring a glow on sticking the wall of the release tube. That is why they may be known as canal rays.
06. The e/m cost for fantastic rays is exceptional for exceptional gases however that of cathode rays is identical. Explain.
Cathode rays are electrons that might be comparable in nature for all of the gases. But fantastic rays are fantastic ions of the fueloline used withinside the discharge tube. All the gases have exceptional mass so the e/m cost is exceptional for exceptional gases. Hydrogen is the lightest fueloline so it has the very best e/m cost.
07. The e/m cost for fantastic rays received for hydrogen is 1836 instances much less than that of cathode rays. Explain.
The mass of an electron may be very small than that of proton or hydrogen fantastic rays. The mass of the proton is sort of 1836 instances extra than that of the electron. The cost of e/m is inversely associated with the mass.
08. The ability electricity of the bonded electron is terrible. Explain.
The free-electron has no enchantment with the nucleus and is taken into consideration to be at an endless distance from the nucleus. So its ability electricity is 0. When the electron comes towards the nucleus its ability electricity decreases that are represented with the aid of using the terrible sign.
09. The general electricity of the electron is likewise terrible. Explain.
The general electricity of the electron is the sum of ability and kinetic electricity. Kinetic electricity is fantastic however the ability of electricity is terrible. When each energy is added, the full electricity turns terrible.
10. The electricity of an electron is inversely proportional to n 2, however, the electricity of better orbits is constantly extra than the ones of the decreased orbits.
According to the electricity equation of Bohr’s model, the Energy of an electron is inversely proportional to n2. Greater may be the cost of n extra maybe the electricity as it has terrible sing. Hence electricity will increase with the aid of using growing n and its most cost are 0 whilst n is identical to infinity.
