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.

How many neutrons does the element Sc have?
The element Scandium (Sc) has 21 protons in its nucleus, which can be determined using its atomic number. To find the number of neutrons, we can subtract the atomic number from the atomic mass: Scandium has an atomic mass of approximately 45. This gives us 45 - 21 = 24 neutrons in a Scandium atom.
How many neutrons in scandium 49?
Number of neutrons = mass number - atomic number = 49 - 21 = 28
What is the atomic mass of an atom with 23 protons 24 neutrons and 25 electrons?
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.
Is scandium soft or hard?
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.
How many protons and electrons and nuetrons does scadium have?
Scandium's, or Sc's, atomic number is 21. Its most common isotope has an atomic mass of 45. Since an electrically neutral atom's atomic number is equal to its number of protons as well as its number of electrons; and since the number of neutrons in a particular isotope of an atom is equal to its atomic mass minus its atomic number, the number of neutrons of the most common isotope of neutral scandium is 45 - 21 = 24.
How many protons and neutrons are there in the element scandium?
21 protons and 24 neutrons in the only stable for. But there can be as few as 15 and as many as 39 neutrons.
How many electrons neutrons and protons are in scandium?
Because its atomic number is 21, it has 21 protons, 21 neutrons, and 21 electrons.
How many neutrons does the element Sc have?
The element Scandium (Sc) has 21 protons in its nucleus, which can be determined using its atomic number. To find the number of neutrons, we can subtract the atomic number from the atomic mass: Scandium has an atomic mass of approximately 45. This gives us 45 - 21 = 24 neutrons in a Scandium atom.
How many protons neutrons and electrons in scandium?
No.of protons of scandium is 21 (ATOMIC NUMBER) ATOMIC NO=no.of proton or electron MASS NO=no of proton+ no.of neutron
How many neutrons in scandium 49?
Number of neutrons = mass number - atomic number = 49 - 21 = 28
How many protons neutrons and electrons are in Sc atomic number 44?
Sc is actually atomic number 21, there are 21 protons, 21 electrons, and usually 24 neutrons
What is the atomic mass of an atom with 23 protons 24 neutrons and 25 electrons?
