What is the mass number of an electron? Electrons: Electrons are small, negatively-charged subatomic particles. They orbit the nucleus of an atom. The number of electrons often equals the number of protons in the nucleus because their negative charge helps to balance the positive charge of the...
What is a boson particle? What is a lepton? What is the relative mass of an electron? What is a mass defect in nuclear physics? What is nuclear decay? How much does a neutron weigh? What is a neutron bomb? What has the Higgs boson done for us?
The electrons on the outer orbit of the atom are called valence electrons. With enough outside force, a valence electron can escape orbit of the atom and become free. Free electrons allow us to move charge, which is what electricity is all about. Speaking of charge... Flowing Charges As...
But that doesn’t mean that platinum has ionic charges of +2 or +4. PtCl2 and PtCl4 are two simple halides of platinum with oxidation states of +2 and +4. Platinum is also found in some organic compounds. Platinum is electron configuration is given below: Pt(78) = [Xe] 4f14 5d...
Electron Transport Flow of electric current depends on free electron mobility between metal contact components facilitated by: Direct metal-metal joints –Valence shell electrons move through overlapping orbital molecular structures Galvanic effects –Electrochemical potential differences drive charge transfer in...

So, in the case of our invisible black hole, we might have been able to notice it by seeing how the light coming to us from a certain section of the sky was bent relative to our expectations, knocked slightly off course by passing close to an object bending the surface of the ...
Voltammetry is the study of the current response of a chemical under an applied potential difference using a potentiostat. Voltammetry encompasses a number of different methods, each of which can tell us about the kinetics and thermodynamics of electron addition (reduction) and electron loss (...
