Chlorine has an atomic mass of 35.453, atomic number 17, is a member of the halogen family (VIIA), and its symbol is “Cl”. Chlorine contains 17 protons and 18 neutrons in is nucleus. There are two isotopes for chlorine as well; Cl-35 and Cl-37. Chlorine was discovered in 1774 by...
What is the total number of atoms contained in 2.00 mole of chlorine gas {eq}\displaystyle (Cl_2) {/eq}?Diatomic GasesA diatomic gas is a gas that can only exist when two of its atoms are bonded together. It cannot exist as a single atom. Examples of diatomic gases are...
Lithium is a chemical element that is abbreviated 'Li.' Its name comes from the word 'lithos,' which is a Greek word that means 'stone.' Answer and Explanation: The mass number of lithium is 7. The mass number of any element is equal to its number of protons and neutrons. You can ...
Atoms and/or molecules in two or more elements can join together to form a compound. This compound, which is the basis of matter, may not resemble any of the original ingredients. For example, sodium and chlorine, two highly poisonous elements that are unstable at room temperatures, combine ...
Through a series of case studies, we establish a list of crucial research questions that provide a direction for future research in this field: What is the contribution of chloride binding to chloride transport? What is the path for chloride transport in concrete? How are our findings on ...
The chemical name is composed of the name of the metal,which is written first,followed by the name of the nonmetal,which has been modified to an identifying stem to which is added the suffix-ide. For example,sodium chloride,NaCl is composed of one atom each of sodium and chlorine.The ...
