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.

You must do the electron configuration for all these elements you've been given.
