Tomato, is today the most popular garden vegetable in America. For many years, however, tomatoes (then called love apples) were considered poisonous and were grown solely for their ornamental value. Tomatoes are usually easy to grow and a few plants provide an adequate harvest for most families.
An ion formula is what is called an empirical formula, which simply represents the ratios of atoms in the compound. In sodium chloride, NaCl, for ever atom of sodium, there is an atom of chlorine. Covalent bonds form between atoms that do not have a significant difference in electronegativity.Almost all covalent are formed between non-metals and atoms of the same kind (such as chlorine-chlorine molecules). There are two important types of covalent bonds: non-polar and polar bonds.olecular (covalent) compounds are between only non-metals. (Metallic compounds are between metals and other metals) An io â¦ nic compound is a pure substance that is formed from a metal and a nonmetal. It has a fairly high melting point and is a conductor of electricity when in a molten or aqueous state.
It is covalent bonding. The electrons are shared between the phosphorus and the chlorines. covalent bonding is when electrons are shared between two elements. molecular polarity is a little bit complicated, but I will try to explain ;). PCl3 is an alternation on tetrahedral molecules.It means that P has one lone pair of electrons. This pair of electrons are only attracted to the P nuclei and thus a greater freedom of motion.ow, due to this shape, and also electronegativity (Cl is more electronegative than P meaning that it tends to hog the electrons they share closer to itself), PCl3 is polar. Electrons that are shared tend to flow closer towards the Cl than the P side.
