Why hydrogen ion does not exist? Because the bare nucleus can readily combine with other particles (electrons, atoms, and molecules), the isolated hydrogen ion can exist only in a nearly particle-free space (high vacuum) and in the gaseous state. Why are H+ ions? Loss of an electron from H atom results in H+ . ion […]

Why is a 1982 D penny rare?
Why is a 1982 D penny rare? Newly found 1982-D Small date copper cent. The Mint switched over from striking copper-alloy to copper-plated zinc planchets sometime in mid-1982 as a cost saving measure – the copper-alloy planchets were too expensive to strike and the Mint was losing money.

Does light slow down in glass?
Does light slow down in glass? We all know that light bends when it travels through glass, water, or other transparent material. Electromagnetic waves simply travel slower through glass than through air. So the wave crests are closer to each other, but the light still oscillates the same number of times per second. It stays […]
What is the working principle of capacitor?
What is the working principle of capacitor? A capacitor works on the principle that the capacitance of a conductor increases appreciably when an earthed conductor is brought near it. Hence, a capacitor has two plates separated by a distance having equal and opposite charges. What is the main function of capacitor? A capacitor is an […]
