26 is the atomic mass because the number of protons and neutrons together = atomic mass
An atom with 24 protons and 13 neutrons would be chromium-37. This isotope of chromium has 24 protons in its nucleus, determining its element, and 13 neutrons, which along with the protons form its atomic mass.
The element with atomic number 25 is manganese. It has known isotopes with mass numbers including every integer from 49 to 60 inclusive, along with 62. However, the only one that is naturally occurring is the one with mass number 55.
In a carbon-13 (C-13) atom, there are 6 protons (from the element carbon) and 7 neutrons (mass number 13 minus the number of protons). Since the atom is electrically neutral, there are also 6 electrons to balance the charge from the protons.
an element always has as many electrons as protons...... the Atomic Number equals the number of protons. So if your atomic number is 13......you have thirteen protons.....and therefore 13 electrons
13 protons means it must be aluminum (Al). 15 neutrons means its atomic mass will be 28. This is not aluminum's most abundant isotope, but it is still aluminum.
The atom in question has 13 protons, so is atomic number 13, which is Aluminium. Assuming that all of the atom's mass is formed from the protons and neutrons, and each of these have atomic mass 1, the number of neutrons is 27 - 13 = 14 neutrons. Almost all Aluminium is of this isotope.
The atomic mass is the sum of the number of protons and neutrons in an atom. In this case, the atomic mass would be 14 (protons) + 13 (neutrons) = 27.
The mass number of this atom is 23, the sum of the number of protons and neutrons.
the atomic mass of carbon 13 is 13 lt has six protons how many neutrons does this isotope
The atomic mass of the isotope 15N is 15,000 108 898 2(7).
Aluminum is 13 because that is the atomic number (the number of protons). The atomic mass number is the number of protons and neutrons in an atom. In this, you just subtract the number of protons from the mass number. If Aluminum (Al), #13, has a mass number of 27, then it has 14 neutrons. Pretty simple.
The atomic number is equal to the number of protons in the nucleus. The mass number is equal to the total number of nucleons (both protons and neutrons). Therefore, there are 13 protons and neutrons, 6 of which are protons, leaving the remaining 7 to be neutrons. In short, 6 protons, 7 neutrons. You're referring to carbon-13, an uncommon isotope of carbon. Sharondenadel The atomic number is equal to the number of protons in the nucleus.

Number of protons = atomic number = 6 atomic units Number of protons + neutrons = mass number = 13 atomic units
An aluminum atom has 13 protons, 14 neutrons, and 13 electrons. The number of protons determines the element (which in this case is aluminum), while the sum of protons and neutrons determines the isotope of the element.
