The mass number of an atom is the total number of protons and neutrons contained within the nucleus of the atom. The number of protons determines the element and will always equal the atomic number of that element. The number of neutrons can change and will determine which isotope of that ...
What is the mass of an electron in AMU? What is the mass number of an oxygen atom with 7 neutrons? An atom has a mass number of 24 and 13 neutrons. what is the atomic number of this atom? An atom has a mass number of 25 and 13 neutrons. what is the atomic number of this ato...

What is the mass of a single hydrogen atom?Number of molesThe number of moles can be defined as the ratio of the given mass to the atomic mass, or it can be the ratio of the number of the particles to the Avogadro number.Answer and Explanation: ...
How do determine the mass number of the element U not the atomic mass? The atomic number of an atom of an element is 17 while its mass number is 35. How many neutrons does the atom have? How do you find the atomic mass of an element?
Each element in theperiodic tableconsists of atoms, and each atom has a unique atomic mass and unique atomic number. The atomic number refers to the number of protons in the atom's nucleus, while atomic mass reflects the sum of the number of protons and neutrons. It is expressed in AMU ...
The number of protons in an atom is unique to each element. For example,carbonatoms have six protons,hydrogenatoms have one andoxygenatoms have eight. The number of protons in an atom is referred to as the atomic number of that element. The number of protons also determines the chemical be...
(called "nucleons") is called the mass number. For example, the element Carbon-12 is so-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 ...
isotopes are radioactive-meaning they "radiate" energy as they decay to a more stable form, perhaps another element half-life: time required for half of the atoms of an element to decay into stable form. Another example is oxygen, with atomic number of 8 can have 8, 9, or 10 neutrons...
An atomic number 1 points out that the atom is hydrogen. Similarly, an atomic number 2 reveals helium atom. The total number of neutrons and protons, when added together, gives us the relative atomic mass. For example, hydrogen holds a relative atomic mass of 1, whereas helium has a ...
