WebAn aqueous solution of an unknown salt of gold is electrolyzed by a current of 2.75 amps for 3.39 hours. The electroplating is carried out with an efficiency of 93.0%, resulting in a deposit of 21.221 g of gold. a How many faradays are required to deposit the gold? b What is the charge on the gold ions (based on your calculations)? WebA proton is one of the subatomic particles that make up matter. In the universe, protons are abundant, making up about half of all visible matter.It has a positive electric charge (+1e) and a rest mass equal to 1.67262 × 10 −27 kg (938.272 MeV/c 2)— marginally lighter than that of the neutron but nearly 1836 times greater than that of the electron. truscott construction

WebSince the 6s orbital with one electron is contracted, this electron is more tightly bound to the nucleus and less available for bonding with other atoms. The 4f and 5d orbitals expand, … WebThe number of electrons in each element’s electron shells, particularly the outermost valence shell, is the primary factor in determining its chemical bonding behavior. In the … WebThe symbols of magnesium and chlorine are written as, A covalent bond representing two electrons is placed as a line between chlorine and magnesium atoms. 4.Neon, with its configuration ending in s2p6, has eight valence electrons. 5.one valence electron In the case of gold, there is only one valence electron in its valence level. 6. truscott drive and lewisham drive
