1.how are the atomic numbers and the atomic masses of the elements related to how the elements are arranged on the periodic table?2.how does the number of electrons relate to the arrangement what is the different in the number of electrons in a 3rd period element and the 2nd period ...
Ions are formed when an atom either loses or gains electrons. The number in thesuperscriptwill tell you the magnitude of this change. Say you have Cl-. How many electron, protons and neutrons does this ion have? The process for finding these values is very similar to what was done above...

In covalent bonds within molecules, the individual atoms contained share electrons to make the molecule stable. Oftentimes, these bonds result in one of the atoms, which has a stronger attractive force than the others, bringing the electrons toward itsel
When figuring out how to calculate the atomic mass of asingle atomof an element, add up the mass ofprotons and neutrons. Example: Find the atomic mass of an isotope of carbon that has 7neutrons. You can see from the periodic table that carbon has an atomic number of 6, which is its...
