WebThis result caused Rutherford to infer. answer choices. that electrons move in orbits around the nucleus of an atom. that atom's positive charge must be clustered in a tiny region in its center. that electrons have almost no mass. that an atom consists of the negative charges scattered in a ball of positive charge. 2. WebAs described earlier, the periodic table arranges atoms based on increasing atomic number so that elements with the same chemical properties recur periodically. When their electron configurations are added to the table ( Figure 6.29 ), we also see a periodic recurrence of similar electron configurations in the outer shells of these elements.

WebNov 4, 2024 · Here is a table of element valences. Remember that an element's electron cloud will become more stable by filling, emptying, or half-filling the shell. Also, shells don't stack neatly one on top of another, so don't always assume an element's valence is determined by the number of electrons in its outer shell. Table of Element Valences Sources WebThe fundamental cause of these patterns is atoms' electron configurations. Atoms with an equal number of positively charged protons and negatively charged electrons are only included in the periodic table together with isotopes, which are atoms with the same number of protons but differing quantities of neutrons.

"WebAn isotope is one of two or more species of atoms of the same chemical element that have different atomic mass numbers ( protons + neutrons ). The atomic weight of helium is 4.002602, the average that reflects the typical ratio of natural abundances of its isotopes. Atomic weight is measured in atomic mass units (amu), also called daltons.
