WebMay 7, 2024 · It is readily apparent that both sodium and lithium have one s electron in their valence shell. We would therefore predict that sodium and lithium have very similar chemistry, which is indeed the case. Now we have explained why elements in the same group have similar chemical properties. Web4; 20 electrons. Two are in the first shell, eight in the second shell, eight in the third shell, and two in the fourth shell.

WebThe first electron shell can hold two electrons, the second electron shell can hold eight electrons, and the third electron shell can hold eight more electrons. Beyond the third shell, electrons arrange themselves a bit differently. So while the shells increase in size from there, for our purposes, we can focus on the first three shells. WebWe can therefore correctly infer that period 3 elements all have three electron shells. However, they have different numbers of electrons. An element's atomic number tells us … WebThe shell closest to the nucleus, 1n, can hold two electrons, while the next shell, 2n, can hold eight, and the third shell, 3n, can hold up to eighteen.
