Yes, that is very good and a good bit above the average. Anything between about from 90 to 110 is average.
Well, darling, the average of 51, 52, and 56 is 53. That's right, just add them all up and divide by how many numbers you have. In this case, it's as easy as pie.
115.5555 repeating
It an be divided evenly by: 1, 131.
The number 131 is a prime number, which means it can only be divided by 1 and itself. Therefore, the only pair of whole numbers that can multiply to equal 131 is 1 and 131. In other words, 1 x 131 = 131.
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
Iodine is element number 53 and and so has 53 protons. There are thus 131-53 = 78 neutrons
No. 6943 = 53 * 131
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.
The atomic number is the same as the number of protons in the nucleus of the particle. Therefore, every atom, ion, and isotope of iodine has an atomic number of 53 (regardless of its mass number).
Q
you can find the number of protons by looking at the atomic number (53), as the number of protons does not change between isotopes. You can find the number of neutrons by subtracting the atomic number from the atomic mass (131), therefore, iodine-131 has 53 protons and 78 neutrons.
Iodine-131 has 53 protons and 53 electrons. The number of protons in an atom defines its element, so it remains iodine with 53 protons despite being a radioactive isotope.
The mass number for iodine is 131, which is the sum of the protons and neutrons. Iodine has 53 protons and 53 electrons, if neutral. To find how many neutrons iodine has subtract 53, the number of protons from the mass number of 131. This shows that iodine has 78 neutrons.
The mass number for iodine is 131, which is the sum of the protons and neutrons. Iodine has 53 protons and 53 electrons, if neutral. To find how many neutrons iodine has subtract 53, the number of protons from the mass number of 131. This shows that iodine has 78 neutrons.
The atomic number of iodine is 53 so there are 53 protons in the nucleus, irrespective of which isotope you are considering. 53 is the atomic number and defines iodine.
