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.
In a neutral atom, the number of electrons is the same as the number of protons. The atomic number of aluminum is 13. A neutral atom of aluminum has 13 protons and 13 electrons. The ground state electron configuration for aluminum is #1s^22s^22p^63s^23p^1#. A shorthand way to write the electron configuration, called noble gas notation, is #[Ne]3^23p^1#.
