I remember seeing one at a Fedco or Sears in the 90s. There isn't much info about the MX-S2 online...
15 in s1 and 16 in s2
Born This Way. S2 Ep18.
S2|E10 That Old Black Magic
The alkaline earth elements electron structure end in s2
All noble gases have the electron configuration s2p6.
S2- ion: [Ne]3s23p6
s2,s2 p6.s1
The area is 72 square units. Explanation: the diagonal,d, is the hypotenuse of a rt. triangle whose legs are both s, the side of the square, so d2= s2 + s2 = 2s2 Therefore , the area of the square , s2 = d2/2 = (12)2/ 2 = 144/2 = 72.
8 valence electron
All alkaline earth metals have electron configurations ending in s2; 6s2 would be the alkaline earth metal in period 6 of the PTE, which is barium.
it S2-, because when you add electrons, you are making the atomic radius bigger. In S2-, you add 2 electron, making it bigger. hope that helped.
phosphorus has 15 protons and electrons: 1 s2 2 s2, 2 p6 3 s2, 3 p3 This adds up to a total of 15 electrons.

By the position of an element on the periodic table you can tell how many protons the element has in it by looking at the number above the elements symbol. You can also find the electron configuration with that same number then you can and you can you can also tell if it is f1, f2,f3...s1,s2,d1,d2...
