What are some metals on the periodic table? What is the valence electron configuration for the bromine atom? What is the state of matter of krypton? Which element has a complete valence electron shell? What family does copernicium belong to on the periodic table?
Why does chlorine have a higher electronegativity value than krypton? What H+ ions of an acid and the OH- ions of a base means. What is the difference in macroscopic properties between covalent and ionic bonds? What are the products of the reaction between the two compounds NaOH(aq) and ...
A molecule is the smallest amount of a compound: a substance made from two or more atoms. Some people find molecules and compounds confusing. Here's how to remember the difference. If you join two different chemical elements together, you can often make a completely new substance. Glue two...
This was later proven to be untrue when some noble gas compounds were discovered. 3. The gases are elements, which share similar properties. These properties include being monoatomic, colorless, odorless, being able to conduct electricity, and having low chemical reactivity. Noble gases include ...
What are some lab assessments to make with fluid and electrolyte imbalances? Why does chlorine have a higher electronegativity value than krypton? If salt lowers the melting point of ice, what does that mean? What will cause the ice to melt?
Matter explained: Atoms, molecules, elements and compounds Fundamentally, matter is composed of elementary particles calledquarksandleptons, both of which are considered elementary particles in that they aren't made up of smaller units of matter. Quarks -- groups ofsubatomic particlesthat interact by...
The scientific study of matter's characteristics and behaviour is known as chemistry.andare different from the normal vocabulary. It is a branch of natural science that examines the building blocks of matter, including the atoms, molecules, and ions that make up compounds and their composition, ...
Ninov had come to Berkeley from GSI in Germany, where he had already been involved in the discovery of elements 110–112. The Berkeley team used cold fusion experiments, firing krypton at lead. Hugely respected in the field, Ninov processed the results using GSI’s software; as the only ...
Classify each element as an alkali metal, alkaline earth metal, halogen, or noble gas. a. sodium b. iodine c. calcium d. barium e. krypton Select the most nearly correct statement: (a) All metals are magnetizable. (b) Some metals are magnetizable. (c) No metals are magnetizable. ...
Helium is a gaseous element with an atomic number of two. It is an inert gas which means that it does not react with other elements to from compounds. Nuclear ReactionsA nuclear reaction is one in which the nucleus of an atom undergoes some physical change, such as losing or gaining a ...
