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.
Call on a student to break the word into its prefix and root (poly, atomic). Call on another student to explain what poly means, an then another to explain what polyatomic must mean. Explain that a polyatomic ion is an ion (review this word if necessary) that has more than one atom in it.
