What is the atomic number for uranium-235? What is the atomic number of oxygen-16? What is the difference between atoms and protons? What is the atomic number of an atom that has 6 protons, 6 neutrons, and 6 electrons? Why is atomic mass unit of an atom never an whole nu...
What is the atomic mass of iron? Atomic Mass of Iron An element's atomic mass is equal to the sum of the individual particle masses of an atom. Atoms have three basic particles which include protons, neutrons, and electrons. The standard unit for measuring atomic mass is the Dalton (u)...
The more protons and neutrons contained in an atomic nucleus, the heavier that element is. So, for example, lead has 82 protons and between 120 and 132 neutrons in its nucleus, whereas hydrogen, the lightest element, has just one proton and occasionally one or two neutrons. The number of ...
What is the most common isotope of argon? Isotopes Explained: Elements are classified by the number of protons in the nucleus of the atom. However, there is no set rule for how many neutrons can be in the atom's nucleus. Because this number can vary, we classify the different, naturally...
26. By how much will the mass number change during alpha decay? a. 1 b. 2 c. 3 d. 4 27. what characteristic is necessary for a material to be used as a control rod? a. it must react with uranium b. it must absorb neutrons without...
The total number of protons present in the atom of a substance is known as theatomicnumber. Atomic mass refers to a weighted average of the number of neutrons and protons in the atom. The number and mass for each type of atom is listed in the periodic table. ...

Scientists haven't seen any indication that there is anything smaller than a quark, but they're still looking. The strong force was first proposed to explain why atomic nuclei do not fly apart. It seemed that they would do so due to the repulsive electromagnetic force between the positively ...
named because it has a mass number of 12 – derived from its 12 nucleons (six protons and six neutrons). However, elements are also arranged based on their atomic numbers, which is the same as the number of protons found in the nucleus. In this case, Carbon has an atomic number of ...
