Working out the charges of ions - BBC Bitesize
Iron is required for life. The iron–sulfur clusters are pervasive and include nitrogenase, the enzymes responsible for biological nitrogen fixation. Iron-containing proteins participate in transport, storage and use of oxygen. Iron proteins are involved in electron transfer. Examples of iron-containing proteins in higher organisms include hemoglobin, cytochrome (see high-valent iron), and catalase. The average adult human contains about 0.005% body weight of i… WebAug 15, 2024 · The number of electrons lost, and so the charge of the ion, is indicated after the chemical symbol, e.g. silver (Ag) loses one electron to become Ag +, whilst zinc (Zn) loses two electrons to become Zn 2+. What is an anion? An anion has more electrons than protons, consequently giving it a net negative charge. poplar ridge farm goshen va
