What Wrench Will Protect Chrome Fitting

How many electrons fit in each shell of the atom (not just the first 3 shells)?

In theory, the number of electrons that can fit into shell n is given by 2n². So the 5th shell could hold up to 2(5)² = 2(25) = 50 electrons. The 6th shell could hold up to 2(6)² = 2(36) = 72 electrons.In reality, there aren’t any atoms on the periodic table that have 50 electrons in their fifth shell (nor any that have 72 electrons in their 6th shell, or 98 electrons in their 7th shell, etc.) Due to the peculiarities of quantum mechanics, electrons start filling higher shells before the lower shells are “complete”. Ergo, the last element on the periodic table — the recently named oganesson — is expected to have 118 electrons arranged into seven shells, like so: 2.8.18.32.32.18.8.If/when element 119 is synthesized, scientists expect it to have eight energy levels, like this: 2.8.18.32.32.18.8.1.

Is it sufficient to finger-tighten the trap under a kitchen or bathroom sink?

I’ve been a master plumber since age 29. Lots of years!You can finger tighten the tubular PVC traps under sinks if they have larger fins to grab onto AND if you’re exceedingly strong.It’s much SAFER to just tighten them 1/4-turn using a large adjustable channel-lock pliers. I’m using one of these pliers in the photo below to undo the nut that holds the pop-up lever in place in a vanity tailpiece drain pipe.Read this simple column:How To Clear a Clogged Bath Sink Drain - Ask the Builder

Are soda/pop bottles the only remaining remnant of the United States' failed attempt to convert the general public to accepting the metric system?

It’s not the general public that needs convincing, they are all for it. it’s the difficulty in some industries to justify TWO systems existing at once, such that the overlap causes MISAPPLICATION of the wrong fitting, nut or screw, such that DAMAGE occurs.Take a small compression nut on HPLC systems, it takes a 1/4″ wrench to tighten it- if instead it were metric, the HOW could you tell?Using too large of a wrench on it simply damages the faces of the nut. So if you had newer metric models of a system sitting next to the previous yer versions, mistakes are a ‘given.’ Added to that. the quarter inch model has been made for 50 years, and sourcing it is cheap; the ‘metric’ equivalent is three times the price. Add to that, would be the need to anodize the outside to a ‘non-chrome’ color , so the two fittings won’t be confused. Both the factories and the customers spare parts inventory would need be doubled.Addressing some of the issue is common adoption of 3/4 inch nuts, same as 19mm, and 7/16″ as being equivalent to 11mm. Even BMW bows to this commonality for the selection of bolts used on their engines.For temperature, the Fahrenheit version has some advantages. It’s almost twice the ‘resolution’, so the use of a decimal treatment to express temperature (of weather, or body temp) by Centigrade requires an extra (decimal) place to express the same value accurately. Your either 98.6F or 37.00CBut NO chemistry or physics class works with anything other then the Metric system. (You’re no doubt familiar with Celsius, Fahrenheit and Kelvin; I had a situation where the scale was degrees Rankine!)When you change the way you look at things, the things you look at change.

I'm fixing a busted slip joint nut on the p-trap of my bathroom sink. How do I safely remove the pipe that is connected to the wall to so I can pull the old nut off and put the new nut on?

I would count on your losing the wall tube and would recommend replacing the entire p-trap, as well as the badly corroded threaded tailpiece shown in the foreground of your photograph.  The brass adapter at the wall requires a brass ring, or ferrule, to seal and support the wall tube correctly.  I would further recommend using 17 gauge tubular products, not your typically sold lighter gauge brass tubing.  It is worth every penny in preventing having to do it again, and it holds up better.  If it is worth doing, do it well.DO NOT use a pipe wrench on these nuts, as they crush the nut and distort it, causing leaks.  Use a slip-joint plier with a bit of cloth to protect the chrome, use all-new gaskets everywhere, and do not over-tighten.  You can also use a strap wrench to prevent damage to chromed tubing and nuts.  Avoid use of a torch or any source of combustion, as gases escaping from the vent can be flammable (although this isn't normally an issue, it is best to advise that it is possible.)  You should cover any open drain piping with a seal of some type to prevent sewer gases entering the home unimpeded, a plastic bag and a rubber band work great for short-term sealing while you go shopping for the necessary parts.You can try gripping the wall tube right next to the brass ferrule with a slip-joint plier while holding the other pipe with a wrench and you MIGHT get it to move without crushing the wall tube, but I wouldn't count on it.As a cost-saving measure, if local codes allow you might replace the trap with an ABS or PVC one, but you will lose the aesthetically pleasing appearance of properly-installed tubular chromed brass.Incidentally, the wall should be sealed tight against insects scurrying along the pipes and into the living spaces with caulk or plaster.

What are the must have accessories that can be installed in Maruti Suzuki Baleno Delta petrol version?

Well I purchased a Delta petrol, can suggest a few things.1 - Full floor lamination (full matting)2 - 3M Nomad floor mats (they keep the dirt and water at a single place and do not let it spread, also the dirt is not visible making the car floor appear cleaner).3 - Steering cover, although its all about preferences. My brother feels that hands slip on the steering, I dont feel that way. So you can decide on that.4 - Seat covers. Delta does not come with seat height adjustment. So if you feel that the visibility is lacking then the best thing to do is put on some seat covers with ample cushioning, this raises the height of the seats a bit making the visibility a tad better.I dont think you need any more must have accessories. I can suggest a few Jazz up accessories that I put.1 - Door anti-hit strips (just show off, useless actually).2 - Door visors (prevent water droplets from falling in the car, useless for me as I hardly open the windows, these further add to the already huge blindspot in the car).3 - Chrome window linings. I got these and they look really classy. Was going for the full car chrome kit but saw a Ray blue baleno with it and it looked really cheap. So chucked the idea.4 - Clear coat paint. Adds to the glossy finish of the car, prevents minor scratches and damages done by bird droppings, etc.You can also go for the alloy rims and get tyre upgrades (do not get the tyre with a width more than 20mm from the current), and also get the car done in 2 tone paint, like the Brezza. Do share the pics of the mods that you do. Happy driving.
