IT has recently been suggested by Bondi and Ly ttleton1,2 that the magnitudes of the electric charges on the proton and electron may differ by a little more than one part in 1018, in which case electrostatic forces would cause the universe to expand. In
The matter is constituted of positively charged protons and negatively charged electrons. For a neutral matter, the number of protons equals the number of electrons. The charge of each electron and each proton are equal and opposite of each other....
But when elements lose or gain an electron (or more than one) and becomeions, things get a little more complicated and you have to consult a periodic table to find out what the charge is likely to be. The Charge of Elements In their standard forms, elements haveno net charge. The numb...
It has long been proposed that phase-separated compartments can provide a basis for the formation of cellular precursors in prebiotic environments. However, we know very little about the properties of coacervates formed from simple peptides, their compat
