Chromate: Polyatomic Ions

Decent Essays
Chromate
The Prefix word “poly” implies to the word many, but even ions of two atoms are usually referred to as polyatomic. Majority of the Polyatomic ions that are used with Oxygen will have the word “ate” in them. Nitrate is an example of a Polyatomic Ion. Polyatomic Ions are referred to as a radical, and less commonly, as a radical group. There are many differences between a polyatomic ion and a compound. Polyatomic ions are composed of two or more atoms that are linked to covalent bonds. Yet, they still have a net deficiency or surplus of electrons, resulting in an overall charge on the group. Polyatomic ions are created when a number of atoms come together to form a group. That group then has either a positive or a negative

    An isotope is an atom containing different numbers of neutrons, differing in atomic mass. Basically an atom with a different atomic mass. What’s special about radioactive isotopes is that a radioactive isotope has a nucleus that decays spontaneously giving off particles and energy. 6. Radioactive tracers are used in science to label certain chemical substances, so metabolic processes can be followed and substances can be located in an organism.…

A procedure in which a small amount of DNA material is immersed in concentrated solution, cesium chloride (CsCl), and soon after placed in centrifuge until the point where equilibrium is achieved is called density-gradient centrifugation. Contrasting techniques involving diffusion and sedimentation form a persisting CsCl concentration gradient. Furthermore, the concentration gradient and pressure of centrifugal force results in increased density.…

    An ion is an atom with a charge due to changes in the number of electrons (negatively charged particles) in the atom. Ions that have lost electrons have a positive charge, and are called cations. Ions that have gained electrons have a negative charge, and are known as anions. Examples of…

    The attraction that holds the oppositely charged ions together in the ionic compound is called an ionic bond. Ionic compounds are hard, brittle solids with high melting points. Most ionic compounds are also electrolytes, which are compounds that separate into ions when they dissolve in water, producing solutions that conduct electricity. In addition, most ionic compounds form three-dimensional crystals, in which many of each kind of ion in a fixed ration are held together by their ionic bonds. Sodium hydroxide is an ionic compound, which sodium is the metal cation (Na+), and hydroxide is the non-metal anion (OH-), more specifically, sodium Hydroxide’s hydroxide is a polyatomic ion, an ion made up of more than one atom that acts as a single particle.…

    Palladium is a chemical element with symbol Pd and atomic number 46. It is a rare and lustrous silvery-white metal discovered in 1803 by William Hyde Wollaston. He named it after the asteroid Pallas, which was it’s named after the epithet of the Greek goddess Athena, acquired by her when she slew Pallas. Palladium. Over half of the supply of palladium and its congener platinum goes into catalytic converters, which convert up to 90% of harmful gases from auto exhaust (hydrocarbons, carbon monoxide, and nitrogen dioxide) into less-harmful substances (nitrogen, carbon dioxide and water vapour).…

    The structure of an atom is very complex, and because of that, its known structure has drastically changed over time. What we know as an atom today is composed of many subatomic particles. There is a positively charged center in an atom called the nucleus, which contains protons and neutrons (Doc. 3). The number of protons determine what element the atom is, and the number of neutrons influences the atom’s mass. There are also negatively charged particles, called electrons, to counteract the positive charge of the nucleus.…

    A compound is defined as a chemical combination of two or more elements. A chemical bond is the “glue” holding together atoms of different elements. Two types of bonds are ionic and covalent. Ionic bonds generally occur between a metallic atom and a nonmetallic atom. The bond results from the transfer of one or more electrons from the metallic atom to the nonmetallic atom, resulting in a charge difference.…

    Originating from cosmic events such as supernovas, chemical elements are the foundation of all life. Billions of years ago, a violent explosion known as the Big Bang produced helium, hydrogen, and all of the matter and energy in the universe. Generated in the cores of stars, nuclei combined to form atoms which constitute the basic unit of all chemical elements. The extensive expansion of the universe induced the birth and demise of more stars and consequently the creation of more elements.…

    Acid and Base Theories Final Paper In the world of science, there are three main theories for acids and bases. Those three theories are the Arrhenius theory, the Bronsted-Lowry theory, and the Lewis theory. An Arrhenius acid is defined as a substance that increases the concentration of hydronium ions in aqueous solution and an Arrhenius base is defined as a substance that increases the concentration of hydroxide ions in aqueous solutions. The definition of a Bronsted-Lowry acid is that it is a substance that donates a proton to another substance.…

    Neutrons are uncharged particles that add mass to the nucleus without adding a charge. The protons are positively charged particles that are also located in the nucleus and symbolized as p+. The second part of an atom is the electron cloud. The electron cloud is a cloud of electron which surrounds the nucleus. The electrons are the third type of subatomic particle- along with protons and neutrons.…

    Types of Spectroscopy used in Organic Chemistry 1.1 Introduction Spectroscopy is the study of the interaction between matter and light (electromagnetic radiation) (Crouch & Skoog, 2007). It is often phrased as the light of knowledge (Reusch, 2013). In the past, spectroscopy started by the study of visible light dispersed according to its wavelength by a prism (Anon., n.d.). Now, with the knowledge of light having both wave-like and particle-like characteristics, with given frequency or wavelength of light is associated with radiative energy called photon. Spectroscopy is used in physical and analytical chemistry because atoms and molecules have unique spectra (Anon., n.d.).…
