WebSure they do. For instance, if you ionize a gas phase atom or molecule with a laser, you get an ion and an electron. Monitoring the kinetic energy of the ejected electron is a typical spectroscopic technique. Yes. Solvated electrons, for example in the Birch Reduction. WebOct 20, 2024 · This is the reason why they can exist even without electrons in the form of an helium ion ( H e 2 + ). It’s stability is accounted by the immense energy that is lost when the four nucleons are bound together. Mathematically speaking, Δ E = ( 2 m p + 2 m n − m H e + 2) c 2 Where,
Extra Questions for Class 9 Science Chapter 3 Atoms and Molecules
WebThe atoms of only a few elements called noble gases (Such as helium, neon, argon and kryton, etc.) are chemically unreactive and exist in the free state or independently. Atoms of most of the elements are chemically very reactive … WebCan an atom exist alone? Atoms can not exist independently. This is because atoms accept electrons or donate electrons to form stable octet fulfilled electronic configurations and this is only possible by formation of molecules. Why atoms can exist independently? simple hedgehog house plans

WebJan 3, 2024 · Answer: Molecules can exist independently. However, the atoms of noble gases (He, Ne, Ar, Kr, Xe) can also exist independently. The basic unit of matter which cannot be broken down into independent particles. ... Atom refers to the smallest constituent unit of a chemical element. WebApr 29, 2024 · An atom is the smallest particle of the element that can exist independently and retain all its chemical properties. A molecule is the smallest particle of an element or a compound capable of independent existence under ordinary conditions. It shows all the properties of the substance. WebAnswer: (a) Atoms of some elements are not able to exist independently. For such elements atoms form molecules and ions. In case of metals and inert gases atoms can exist independently. (b) The number of atoms constituting a molecule is known as its atomicity. E.g.,O 3 → atomicity is 3. O 2 → atomicity is 2. rawls first principle
