Chemical element same atomic number, or number of protons. Nuclear scientists, however, define a pure element as one that consists of only one stable isotope. For example, a copper wire is 99.99% chemically pure if 99.99% of its atoms are copper, with 29 protons each. However it is not isotopically pure since ordinary copper consists of two stable isotopes, 69% Cu and 31% Cu, with different numbers of neutrons. However, a pure gold ingot would be both chemically and isotopically pure, since ordinary gold consists only of one isotope, Au. Atoms of chemically pure elements may bond to each other chemically in
CU Coventry are also offered, designed to help students access higher education without traditional qualifications: CU Coventry CU Coventry is a subsidiary of Coventry University. It has been in operation since its launch in 2012, and was formerly known as Coventry University College. Its campus is located in the city of Coventry, England.
