Post: #6. I pay $75 a week ($300 mo) which I had to negotiate with the salon owner who wanted to charge $125 a week. His location and salon does not warrant higher than $300 a month. The hair stylist are paying $200 a week.
The number of electrons in any atom always equals the number of protons (to make the atom electrically neutral). The atomic number of any element tells you how many protons thâ¦ere are in the nucleus of an atom of that element. The atomic number for platinum (Pt) is 78, and the atomic weight is 195.       Thus, it will have 78 protons.     When electrically Neutral, it will also have 78 electrons.
Platinum is a chemical element with the chemical symbol Pt and the atomic number of 78. Its name is derived from the Spanish term âplatina del Pintoâ, which is literally translated into âlittle silver of the Pinto Riverâ. It was discovered in South America by Ulloa in 1753 and by Wood in 1741.latinum also has 31 synthetic isotopes ranging in atomic mass from 166 to 202, making the total number of known isotopes 37. The least stable of these is 166 Pt with a half-life of 300 Âµs, while the most stable is 193 Pt with a half-life of 50 years.
