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.
A covalent bond is a bond between two nonmetals, where the electrons are essentially shared. For example water is H2O. Oxygen needs two more electrons to have a full valence (â¦ outer shell) and each hydrogen needs one electron, so they share electrons to form the stable compound water.o. A bond cannot be both covalent and ionic. A bond can be covalent, ionic or metallic. In covalent bonding electrons are shared, electrons are transferred in ionic bonding a â¦ nd electrons move about in a sea of electrons in metallic bonds.
