My fee structure is based on an hourly time charge basis. Architectural services (for renovation and new construction): 20% of construction costs. Interior design services: 35% commission on all goods and services.I work a lot of different ways.ypical fee structure is 15-20% of construction costs plus reimbursable expenses. My billing practices are based on a 35% commission over cost to my clients. Then I charge a basic design fee to initiate my contracts of usually $100,000. This fee varies, however, on the size and scale of the project.
A polyatomic ion, also known as a molecular ion, is a charged chemical species (ion) composed of two or more atoms covalently bonded or of a metal complex that can be considered to be acting as a single unit. The prefix poly-means many, in Greek, but even ions of two atoms are commonly referred to as polyatomic.ts chemical formula is O H â . An ammonium ion is made up of one nitrogen atom and four hydrogen atoms: it has a charge of +1, and its chemical formula is N H 4 + . Polyatomic ions are often useful in the context of acid-base chemistry or in the formation of salts.
In a polyatomic ion, its number of protons is the total number of protons all the atoms within it. To calculate this, the first step is to determine the number of protons in each atom of the ion. You can use their atomic number to find the number of protons. If the number protons and electrons are equal there is no charge, so the next step is to determine how many electrons to add or remove to the number of protons. Then add them. To calculate the number electrons in the ion. First, add one to the number of protons to find the number of electrons for each negative charge on the ion (-3 ion, add three electrons etc.).
