WebJul 20, 2024 · Neutral sodium atom on left has 11 protons and 11 electrons. Sodium ion on right has 11 protons and 10 electrons, with a +1 overall charge. Anions Some atoms have nearly eight electrons in their valence shell and can gain additional valence electrons until they have an octet. WebJan 15, 2024 · The Aufbau principle states that electrons must fill lowest energy shells first. Following the model, electrons fill the 1s orbital with two electrons, then the 2s with two electrons, then the 2p with six electrons, then the 3s with two electrons, etc. There are some exceptions to the Aufbau Principle.

WebThe neutral atom chlorine (Z=17), for instance has 17 electrons. Therefore, its ground state electronic configuration can be written as 1s 2 2s 2 2p 6 3s 2 3p 5. The chloride ion (Cl - ), on the other hand, has an additional electron for a total of 18 electrons. WebFeb 22, 2024 · Step 1: Write the electron configuration of the atom in the following form: (1s) (2s, 2p) (3s, 3p) (3d) (4s, 4p) (4d) (4f) (5s, 5p) . . . Step 2: Identify the electron of interest, and ignore all electrons in higher groups (to the right in the list from Step 1). These do not shield electrons in lower groups WebThe number of electrons in 1 9 4 0 K + = 1 9 − 1 = 1 8. The number of neutrons in 1 9 4 0 K + = 4 0 − 1 9 = 2 1. The number of electrons plus neutrons in 1 9 4 0 K + = 1 8 + 2 1 = 3 9 Hence, the option (C) is the correct answer. solitary activities for seniors
