Overall composition of the beef animal body (a) Calf (with a body weight of 75 kg) (b) Steer (with a body weight of 500 kg) Note: The values are expressed in grams per kilogram of beef carcass. For example, if lipid is reported as 66 g kg⁻¹ in the calf, it means that 66 grams of lipids are present in every kilogram of the calf’s carcass. Source: Chesworth, J. M., Stuchbury, T., & Scaife, J.

In potassium sulfate, potassium (K) is a metal, and sulfur (S) is a nonmetal. The electronegativity difference between these elements is significant, leading to the transfer of electrons. Potassium loses an electron to become a K+ ion, while sulfur gains two electrons to become an SO4^2- ion. Sulfate needs two electrons so there must be two Potassium ions since it only gives 1 electron. The oppositely charged ions are then attracted to each other, forming an ionic bond. Urea is an example of a covalent bond. It has 1 carbon atom, 1 oxygen, 2 nitrogen, and 4 hydrogen. Notice that carbon forms a double bond with oxygen.
