Fluorine, because it has only two energy levels. All the rest have 3 to 7 energy levels, which increases their atomic radii.

You can see a grey circle with a little white cirle in it with a radius of 3 What is the radius of the diagram's larger circle if the area of the shaded region is 72 pie?
Area of a circle with radius r = pir2Area of the largest circle = Area of the smallest circle + Area of the shaded regionSince areas of the smallest circle and the shaded region are 9pi and 72pi, the Area, A, of the largest circle isA = 9pi + 72pi = 81pi, where r2 = 81.Thus, the radius of the largest circle is 9
What is the smallest perimeter for a shape with the area of sixty Meters squared?
The smallest perimeter for any area is achieved with a circle. The area formula for a circle is A = pi * radius squared. Where pi is a constant equal to about 3.14. In this case, 60 = pi * radius squared, then radius = square root (60 / pi) A circle's perimeter is called the circumference: C = 2 * r * pi So, C = 2 * square root (60 / pi) * pi It is approximately 27.5 meters
Is radius half radius?
No. Radius is half of the diameter.
How do you get from the radius to the circumference?
(radius+radius) times pi
How do you calculate how many square items fit in a round container?
This is an interesting question: very simple but incredibly difficult. I have not found a proper answer but have got a partial answer to a related question: given a number of unit squares, what is the smallest circle that they will fit into. The two are linked very simply: if 2 unit squares will fit in a circle of radius 1.118 then a unit circle can hold 2 squares of a maximum side of 1/1.118 units.The answers given below can be proved only for n = 1 and 2.1 square : radius = sqrt(2)/2 = 0.707 approx.2 squares : radius = sqrt(5)/2 = 1.118 approx.3 squares : radius = 1.2884 squares : radius = 1.4145 squares : radius = 1.58110 squares : radius = 2.12120 squares : radius = 2.89330 squares : radius = 3.485.For all integers up to 35 see www2.stetson.edu/~efriedma/squincir/
