When a balloon is rubbed against a sweater or a person’s hair, the balloon gains negative charges. When the negatively charged balloon is brought close the wall, the electrons in the wall move, leaving the protons exposed, which interact with the negative charge...
A quark (/kwɔːrk, kwɑːrk/) is a type of elementary particle and a fundamental constituent of matter. Quarks combine to form composite particles called hadrons, the most stable of which areprotons and neutrons, the components of atomic nuclei. ... Up and down quarks have the low...
The presence of ionic species in pure water has been confirmed by electrochemical measurements, and their infrared (IR) and Raman spectral signatures have been found experimentally in aqueous solutions and hydrated hydronium clusters5,6; however the assignment of the water ions to actual (observable)...
Protons have slightly less mass than the neutrons in the nucleus, but they are 1,836 times more massive than electrons. The actual mass of the proton is 1.6726 x 10^-27 kilograms, which is a very small mass indeed. The symbol "^-" represents a negative exponent. This number is a deci...
If an atom has 6 protons and has an atomic weight of 14, this element is (a) ___. The atomic number is (b) ___ and the number of neutrons is (c) ___. If atom X has an atomic number of 74, it would have which of the following? A) 74 protons B) 37 protons and 37 ele...
With freeze-thawed (cryoprotective dimethyl sulphoxide) or aged chloroplasts, we observed that the heterogeneous p K of inside-bound neutral red was salt dependent in a way which suggested that neutral red was bound close to the plane of negative fixed charges and that the adjacent inner ...
