84 is the atomic number of polonium. Many roads and highways are named 84 and it is the name of a town in Pennsylvania and that of a lumber company. It is also the number of years it takes Uranus to orbit the sun.
The prodigious number 84 follows the number 83- and it precedes the number 85!
When you divide 84 by 15 you get 5.6 it is saying that when you have the number that you are going to put another number into in this case the number is 84 if you are going to take a evn number an divide it by a odd number then you know that you are going to get a odd number that is why 84\15= 5.6.
84 already is a whole number.
12% of 84 = 12% * 84 = 0.12 * 84 = 10.08
84 is the mass number: 36 proton plus 48 neutrons
84 is the mass number of a stable isotope of krypton, 84Kr has 36 protons and 48 neutrons in its nucleus that give it an atomic weight of 84.
The number 48 in the name krypton-84 represents the atomic number of the element krypton. Atomic number is the number of protons in the nucleus of an atom, determining its chemical properties.
84 is the mass number: 36 proton plus 48 neutrons
The mass number of krypton is 84.
The atomic number of krypton is 36.
In Krypton-84, 84 represents the total number of protons and neutrons in the nucleus of the atom. Krypton is a noble gas element with 36 protons in its nucleus, so the remaining 48 particles are neutrons.
84 is the mass number: 36 proton plus 48 neutrons
Krypton, Kr mass number: 83.8 atomic number: 36
The mass number of 84Kr is 84. It is the sum of the number of protons and neutrons in the nucleus of a krypton-84 atom.
Krypton is a non metal element. Mass number of it is 84.
The Atomic Mass of krypton is 83.80(1) if you round 84
