Number of neutrons = mass number - atomic number = 49 - 21 = 28
Scandium 49 has 24 protons because it is scandium (which has an atomic number of 21) plus 28 neutrons.
The atomic number of scandium is 21. So it has 21 protons and 21 electrons. Number of neutrons depends on the isotope. Number of neutrons = Mass number - Atomic number Sc-45 isotope has 24 neutrons
Scandium is a transition metal that is soft and silvery-white in appearance. It is a malleable and ductile element. Scandium has 21 protons and 24 neutrons.
An element's core properties are determined by the number of protons. 21 protons makes this element Scandium. The number of neutrons that Scandium has is 23 in its normal state. It makes this an isotope of Scandium.
To figure this out look at the mass number of scandium. It has a mass number of 45(im rounding it up to keep it simple). The mass number is the number of protons and neutrons that form the nucleus added together. So if we know 24 of these 45 particles have to be neutrons then there must be(45-24)= 21 protons. To check this awnser we look at the atomic number(the one above the symbol for the element) and we can see that it is 21 for scandium meaning our awnser is correct.
Scandium (natural) is a mono-isotopic element - scandium-45.
The atomic number of scandium is 21. So it has 21 protons and 21 electrons. Number of neutrons depends on the isotope. Number of neutrons = Mass number - Atomic number Sc-45 isotope has 24 neutrons
21 protons and 24 neutrons in the only stable for. But there can be as few as 15 and as many as 39 neutrons.
Scandium's atomic number is 21. Therefore, neutral scandium has 21 protons and 21 electrons. Scandium's only stable isotope is 45Sc, which has 45 - 21 = 24 neutrons.
Because its atomic number is 21, it has 21 protons, 21 neutrons, and 21 electrons.
As all other chemical elements scandium atom has a nucleus (containing protons and neutrons) and a cloud of electrons.
Neither. Neutrons are always neutral, meaning they have no charge.
Scandium is a transition metal that is soft and silvery-white in appearance. It is a malleable and ductile element. Scandium has 21 protons and 24 neutrons.
49 protons, 64 neutrons and 49 electrons.
Indium, atomic number 49, so 49 Protons. Atomic mass 115, so 115-49 = 66 Neutrons.
In-115 isotope has 66 neutrons
An element's core properties are determined by the number of protons. 21 protons makes this element Scandium. The number of neutrons that Scandium has is 23 in its normal state. It makes this an isotope of Scandium.
It has 49 neutrons, 80 mass number (protons and neutrons) and 31 atomic number(protons) so 80-31=49.
