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.
Polyatomic ions are formed when a group of atoms have a charge. Hydroxide, for example, is formed when oxygen and hydrogen covalently bond but still have a charge of -1. When a polyatomic ion forms an ionic bond with another ion, a polyatomic ionic compound is made. For example, the +1 barium ion can form an ionic bond with the -1 hydroxide ion, to form the Barium Hydroxide (BaOH) ionic compound.
