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.
Valence electrons are the outermost electrons, and are the ones involved in bonding. Sodium has 11 electrons: its atomic number is 11, so it has 11 protons. Atoms are neutral, so this means that sodium also has 11 electrons Electrons are arranged in shells or energy levels. The first evel can have 2 electrons; The second level can have up to 8 electrons.
