Sodium gives electrons when reacting with a substance such as Chloride instead of sharing electron in a reaction such as the Hydrogen and Oxygen forming water molecules can be found in the type of bond in each example reaction. Before I can identify the contrasting characteristics of each reaction‚ I must first acknowledge the reason atoms react with one another in the first place. Each element has a certain number of valence electrons‚ an example being Sodium having one valence electron. When elements

Do Electrons Really Exist? Science has defined the nature of the world through an assortment of things that are observed in the physical world and those that are unobservable‚ improvable theories that explain the world. Electrons are unobservable. We cannot experience their existence with our own human senses. Do electrons really exist‚ or are they just useful fictions? Antirealists would explain that they do not exist because you cannot observe them. Realists would argue that electrons

Transport and the environment The chapter examines how transport affects the environment; how its impact can be quantified in economic terms; and how economic incentives can be used to reduce the environmental cost of transport‚ as well as addressing other externalities associated particularly with car use‚ such as congestion. The environmental impacts of transport “Transportation services are essential component of economic activity‚ and are one key to its growth. Transportation has a number

Photosynthesis is the process by which green plants use the light energy to convert carbon dioxide and water into simple sugar called glucose‚ which provides a basic energy source for the plant. Photosynthesis occurs in leaves that contain specialized cell structures called chloroplasts. Chloroplasts contain molecules of a green pigment called chlorophyll‚ consisting largely of carbon and hydrogen. It gives green color and absorbs the necessary light for photosynthesis. Chloroplasts are found in palisade

During an undercover investigation‚ Officer Cline witnessed Defendant #1 purchase a bag of what appeared to be marijuana and LSD. When Officer Cline approached the dealer (Defendant #2)‚ he was given a similar bag. Following the purchase‚ officers approached and arrested both defendants on narcotics violations. Forensic tests later revealed that the contents of the bag were nothing more than honey and dried leaf matter and rolling paper coated with lime extract. The defense attorneys for both defendants

The electron is a fundamental subatomic particle that carries a negative electric charge. It is a spin-½ lepton that participates in electromagnetic interactions‚ and its mass is less than one thousandth of that of the smallest atom. Its electric charge is defined by convention to be negative‚ with a value of −1 in atomic units. Together with atomic nuclei‚ electrons make up atoms; their interaction with adjacent nuclei is the main cause of chemical bonding. The name "electron" comes from
