WebPeriodic trends also exist as you move down a group in the periodic table. For example, as one moves down a group, the atomic radius generally increases. This is because the number of energy levels increases, making the atom larger. Similarly, as one moves down a group, the ionization energy generally decreases. WebSep 17, 2024 · There are four ways to find the charge of an element: Use the periodic table. The usual charge of an element is common to its group. Group 1 (Alkali Metals): 1+.

WebThe amount of charge felt by an electron depends on its distance from the nucleus. The closer an electron comes to the nucleus, or the more it penetrates, the stronger its attraction to the nucleus. Core electrons penetrate more and feel more of the nucleus than the other electrons. E = 1/(4πϵo)⋅(q1q2)/r2 E = 1 / ( 4 π ϵ o) ⋅ ( q 1 q 2 ...
