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. The number of electrons in the outermost shell of a particular atom determines its reactivity, or tendency to form chemical bonds with other atoms. WebGive the maximum number of electrons in an atom that can have these quantum numbers: a. n = 0, l = 0, ml = 0 b. n = 2, l = l, ml = 1, ms = 12 c. n = 3, ms = +12 d. n = 2, l = 2 e. n = 1, l = 0, ml = 0 arrow_forward What is the maximum number of electrons that can be identified with each of the following sets of quantum numbers?
WebJan 30, 2024 · The electron configuration for Ca 2+ is the same as that for Argon, which has 18 electrons. Hence, we can say that both are isoelectronic. The electronic configuration of anions is assigned by adding electrons according to Aufbau Principle. WebA superscript number that designates the number of electrons in that particular subshell. For example, the notation 2 p4 (read “two–p–four”) indicates four electrons in a p subshell ( l = 1) with a principal quantum number ( n) of 2.
