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.
Poly atomic ions are covalent compounds that have an overall charge and therefore are held together through the electrostatic attraction of ionic bonding to positively charged ions called cations. Examples include sulfate, #SO_4^-2#, nitrate, #NO_3^-#, and phosphate, #PO_4^-3#.
