Chemical bonding

these can be transferred to or shared with another atom. Valence electrons are important because they are the ones that determine the effect in a chemical reaction. Valence electrons also help determine where specific elements are located in…

There are numerous scientists who have positively impacted the field of Chemistry; from Robert Bunsen to George Washington Carver, chemists have and continue to shape the publics knowledge of Chemistry. However, one chemist stands out from all the rest because of his historical, societal, and person significance: George Claude Pimentel. Pimentel’s life, work, and contribution to Chemistry have shaped this field and impacted it in ways that other scientists have not. Background George Claude…

metals, such as iron, copper or calcium or non-metals such as carbon, oxygen or nitrogen. Chemistry is concerned with the way atoms link together to form molecules, which are the natural chemical units of matter. Molecules represent the smallest particle of a chemical compound which retains the characteristics and chemical properties of the compound. With the rare exception of certain single atom molecules, almost all molecules consist of two or more atoms linked together. An atom of the…

The purpose of this lab is to calculate the chemical formula of a hydrate compound made up of copper, chlorine, and water molecules by using the law of definite proportions. The water of hydration of the copper chloride hydrate sample will be determined as well as the mass of copper and chlorine through a chemical reaction. The results will be used to calculate the moles of copper and chlorine and then the empirical formula of the compound. Techniques used: In this experiment, different…

The solubility rules were used to determine which reactant was aqueous and which one was a solid. The solid is the precipitate formed in the reaction. The formation of the precipitate indicates that a chemical reaction occurred. If no precipitate formed the reaction would be labeled with DNR, which stands for does not react. The solubility rules states which elements are soluble or insoluble, including the exceptions for each rule. For example at station…

in an alkanol is increased, then the alkanol containing the longest carbon chain will have a higher heat of combustion, because as there are more carbon atoms, more energy will be released as a result of the breaking of the covalent bonding and the forming of bonding as the final product. INTRODUCTION Fuels are hydrocarbons…

The Earth is covered by about 70% of water and naturally, water is the only material that exists in three different states (solid, liquid and gas). This highlights that water is an important component as a chemical substance and this is due to its unique properties. Structure of water is one of the main features of water that allows it to carry out its job and that determines its functions and properties. Structure of water Water the molecule In a water molecule, there is one oxygen that has…

Covalent bonding occurs when atoms share pairs of electrons. Atoms will covalently bond with other atoms in order to gain more stability, which are gained by forming a full electron shell. By sharing their outer most valence electrons, atoms can fill up their outer electron shell and gain stability (Chem wiki) Nonmetals will readily form covalent bonds with other nonmetals in order to obtain stability, and can form anywhere between one to three covalent bonds with other nonmetals depending on…

Molecules are a group of atoms bonded together, representing the smallest fundamental unit of a chemical compound that can take part in a chemical reaction. Molecules are three-dimensional entities and therefore should be depicted in three dimensions. My group decided on the claim that as electrons are bonded to a central atom, the greater the electron repulsion, causing an increase in the bond angles. Bond angles are the angles that are formed between two adjacent bonds on the same central…

concerns the fact that sulfur holds much blame for the nasty occurrence. In fact, this mother of repulsive odors earns its spot on the periodic table as one of the world's 118 chemical elements, or substances that contain only one type of atom. Much like any other non-metal, it does not retain the typical physical and chemical properties of metals, such as luster. The tenth most abundant element in the universe, sulfur additionally sports a multitude of unique characteristics- some even…
