The other process by which an atom can lose protons is known as nuclear fission. In nuclear fission, a device is used to accelerate neutrons toward the nucleus of an atom. The collision of the neutrons with the atom causes the atom's nucleus to break apart into fragments. Each fragment is...
As the exhaled air from the suspect flows past one side of the fuel cell, the platinum oxidizes any alcohol in the air to produce acetic acid, protons and electrons. The electrons flow through a wire from the platinum electrode. The wire is connected to an electrical-current meter and to ...
How does an atom try to fill its valence shell? If you know the atomic number and the mass number of an isotope of an element, how can you determine the number of protons and neutrons? Explain the concept of the mole. How many electrons does aluminium have? Calculate the number of mole...
When an unstable atom disintegrates, it produces particulate radiation, including alpha and beta particles. For example, when radioactive elements like uranium, radium and polonium decay, they release radioactive alpha particles. These particles, made up of protons and neutrons, are large and can ...
Physicists came up with the idea of strange matter in the 1970s when they wondered what would happen if protons and neutrons were squished superhumanly hard [source: Freedman]. Let's repeat a similar version of their theoretical experiment, imagining we have an iron atom, plus a ...
Atomic number:The number of protons in an atom's nucleus is referred to as the atomic number of that element. The number of protons defines what element it is and determines its chemical behavior. For example,carbon atomsalways have six protons;hydrogen atomsalways have one; andoxygen atomsalw...
Is an iron chloride solution a pure substance or a mixture? Explain. How could tellurium dioxide, TeO_2, be separated from SiO_2? How many protons does iodine have? Is table salt a compound? How is sodium formed? How is a compound similar to a homogeneous mixture?
How many protons does argon have? What is the molar mass of argon? How many neutrons are in argon? What is potassium-argon dating used for? What state of matter is argon? What is the electronegativity of argon? What is tellurium used for?
An electron is a negatively charged subatomic particle that orbits the nucleus of an atom. The nucleus consists of positively charged protons and neutrally charged neutrons. The number of protons in the nucleus defines the atomic number of an element, and the number of electrons in a neutral at...
How many chemical elements is hair made of? What determines what kind of chemical element an atom is? How is an atom different from an element? What is formed when atoms form covalent bonds? What does each different element on the periodic table of elements represent?
