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 determines the energy of an electron?ElectronsElectrons are subatomic particles found within the outer shells of atoms. They contain a negative charge and have 1/1836 the mass of the proton. They also play a key role in the electricity, magnetism, and chemistry....
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...
