The normal weight range for your age and height is 89 to 131 pounds. At 136 pounds, you would be considered a little overweight.
it is in the healthy weight range, but gain 5 more pounds than it's considered overweight! Trust me, I'm 131 pounds. It also depends on your height. I'm 5'2 and 12 yrs old too, and I'm trying to lose weight! I am 12 and 130 pounds. I figure it's normal because I'm 5'6.
You are considered to be overweight at 133 pounds at 5 feet 2 inches tall. The normal weight for this height is between 104 pounds and 131 pounds.
B. 53 neutrons. The number of neutrons in an atom is calculated by subtracting the number of protons from the atomic mass of the isotope. Since Iodine-131 has an atomic mass of approximately 131, and it has 53 protons, the number of neutrons is 131 - 53 = 78.
131
92
Iodine is element number 53 and and so has 53 protons. There are thus 131-53 = 78 neutrons
131 pounds is approximately equal to 59.42 kilograms.
Probably about 125 pounds overweight.
No. 6943 = 53 * 131
131 pounds is equal to approximately 59.4 kilograms. To convert pounds to kilograms, you can divide the number of pounds by 2.20462.
The 131 number is the mass number: the sum of the number of protons and neutrons. Iodine has 53 protons and will have 53 electrons if its a neutral atom. To find the number of neutrons, just subtract the mass number with the number of protons 131 - 53 = 78 neutrons. See link below for periodic table.
