Covalent Bonds Covalent bonds are formed when atoms share electrons‚ one from each atom in a single bond‚ to form electron pairs‚ usually making their outermost shells up to eight electrons by this means. This would make them more stable‚ less reactive and an electronic structure like a noble gas. They are most frequently formed between pairs of non-metallic elements. Non-metallic elements usually have from four to eight electrons in their outermost shells‚ the so-called valency electrons‚ which

by tubules or vesicles. These are called the cisternae. The golgi complex accepts vesicles from the endoplasmic reticulum and modifies them for usage in the cell. The golgi complex is used to distribute materials which help form the cell membranes. They also assemble the membranous material by producing glycolipids and glycoproteins. The golgi complexes also hand their vesicles materials for secretion. The golgi complex could not do its job without the help of vesicles. Vesicles bring and
