The structure of the methane, CH4, molecule exhibits single covalent bonds. Covalent bonding involves the sharing of electrons. In the methane molecule, the four hydrogen atom share one electron each with the carbon atom.Know More
Some properties of covalent bonds are that they tend to occur between two non-metal atoms, have low boiling and melting points and low polarity. At room temperature, these covalent molecules are either gaseous or liquids. For example, methane is a gas.
In contrast, ionic bonds tend to be present in solid compounds. Ionic bonds occur between a metal and non-metal. Some characteristics of ionic bonds in compounds are that they exhibit high melting and boiling points.Learn more about Atoms & Molecules
Starch’s structure is composed of the two compounds amylose and amylopectin. The chemical formula for starch is (C6H10O5)n. Starch is a polysaccharide that consist of glucose monomers.Full Answer >
An atom is comprised of a central portion called a nucleus that contains protons and neutrons. Electrons orbit the nucleus and are typically found in a one-to-one ratio with protons. Different stable atomic configurations are called elements. Hydrogen is unique in having one proton, one electron and no neutrons.Full Answer >
Fluorite is composed of calcium and fluorine atoms arranged in a simple cubic, crystalline lattice structure. Calcium atoms in fluorite are arranged in a face-centered cubic arrangement embodying a cube of fluorine atoms. In other words, fluorite is composed of a cubic array of fluorine atoms with a calcium atom in the center of every alternate cube.Full Answer >
Sodium chloride, or NaCl, is an ionic compound with a three-dimensional lattice structure. The sodium ions are positive while the chloride ions are negative. They are attracted by electrostatic nuclear forces, whcih causes the ions to arrange in a lattice structure.Full Answer >
