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.
The Pauli exclusion principle states that you fill up 1 electron in each of these sub-levels before you put the second electron in the same sub-level, so in summary the 3 valence electrons in Antimony have the following quantum numbers: electron 1: n = 5, l = 1, ml = -1 electron 2: n = 5, l = 1, ml = 0 electron 3: n = 5, l = 1, ml = +1.
