What is the principal quantum number of the s and p valence electrons in the following chemical elements? (Enter your answer with integers separated by commas and with no spaces, for example 3,4,1,2,2,1)A) silicon B) aluminum C) carbon D) nitrogen E) cesium F) arsenic
Yep, and we had those silly little collapsable tray holders to put in the living room so we could watch TV while we ate sometimesI even remember when they started putting the little deserts in them.
UmI can remember back when there was no TVnot at least in the area where I lived(early 1960's)
I think soI was born in 1977Maybe we had them in the early 80's.
I'm old enough to remember radio dinners! But I do remember the Swanson TV dinners in aluminum compartmentalized trays.
A) Silicon; Atomic NO.: 14 3s2 3p2 B) Aluminum: Atomic No: 13 3s2 3p1 C) Carbon : Atomic No.: 6 2s2 2p2 D) Nitrogen: Atomic No: 7 2s2 2p3 E) Cesium ; Atomic No: 55 6s1 F) Arsenic ; Atomic No: 33 4s2 4p2 In fact in order to solve such problems you should see their positions in the periodic table and accordingly represent the valence electrons in their outer most orbit or valence shell.
