All noble gases have the electron configuration s2p6.
Its Carbon. C
Are you on NovaNet?
I am. This sucks
Which element has the electron distribution s2d2
Halogens -
Fluorine, 1s22s22p5
Chlorine 1s22s22p63s23p5
etc
F
Ca
The maximum number of valence electrons is SEVEN (7 is total number of electrons in the uncompleted highest level s- and p-orbitals: s2 and p5 = (sp)7)You'll find this mainly in group 17: the halogens, though other elements may also have 7 valences: eg. Manganese in permanganate MnO4-
The atomic weight of an element is a number that takes into account the natural distribution of the isotopes of that element.
The atomic mass of an element is the average of its isotopes, weighted by abundance in nature.
group 17
For phosphorus [Ne]3s23p3
S2- ion: [Ne]3s23p6
Definition: A set S1 is a superset of another set S2 if every element in S2 is in S1. S1 may have elements which are not in S2.
Sulfur
The answer will depend on what p5 is!
p5 cannot be simplified.
The sample mean is distributed with the same mean as the popualtion mean. If the popolation variance is s2 then the sample mean has a variance is s2/n. As n increases, the distribution of the sample mean gets closer to a Gaussian - ie Normal - distribution. This is the basis of the Central Limit Theorem which is important for hypothesis testing.

No, it is not.
If you were to see a P5 that would mean the batter popped out to the third baseman.
A normal distribution is defined by two parameters: the mean, m, and the variance s2, (or standard deviation, s).The standard normal distribution is the special case of the normal distribution in which m = 0 and s = 1.

Group 13 (B, AL, Ga, In, Tl) all have (n)s2 (n)p1 configurations, in wch (n) has a value of 2, 3, 4, 5. Hence they have 3 valence electrons.
