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 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
How many neutrons in scandium 49?
Scandium 49 has 24 protons because it is scandium (which has an atomic number of 21) plus 28 neutrons.
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.
What is the total number of protons if a sample of scandium has a mass of 7.9027?
Interesting question! Let us proceed slowly. Scandium has 21 protons per atom and 6.022 X 10^23 atoms per mole. 21 X 6.022 X 10^23 = 1.26 X 10^25 protons per mole of Scandium. 7.9027 grams Scandium (1mol/44.96g ) = 0.176 mol Scandium 0.176 mole Scandium X 1.26 X 10^25 protons Scandium = 2.22 X 10^24 total protons in 7.9027 grams of Scandium. ( you can put this all into one conversion string if you like )
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 neutrons does the element Sc have?
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
How many neutrons in scandium 49?
Scandium 49 has 24 protons because it is scandium (which has an atomic number of 21) plus 28 neutrons.
How many protons neutrons and electrons in scandium?
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.
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?

what element has 21 protons 21 electrons and 24 neutrons?
chromium
How many protons electrons and neutrons in chromium?
There are 24 protons in Chromium (Cr). The atomic number of an element is the same as the number of protons.
How many protons neutrons and electrons in potassium -43?
There are 19 protons and electrons each. And there are 24 neutrons present.
What element has a mass number of 44?
The closest to 44 is Scandium, which has 21 protons and 24 neutrons, giving it a mass of 44.95591 amu.
What is the total number of protons if a sample of scandium has a mass of 7.9027?
Interesting question! Let us proceed slowly. Scandium has 21 protons per atom and 6.022 X 10^23 atoms per mole. 21 X 6.022 X 10^23 = 1.26 X 10^25 protons per mole of Scandium. 7.9027 grams Scandium (1mol/44.96g ) = 0.176 mol Scandium 0.176 mole Scandium X 1.26 X 10^25 protons Scandium = 2.22 X 10^24 total protons in 7.9027 grams of Scandium.

How many neutrons are there in Cr-54?
Number of neutrons = Mass number - Atomic number = 54 - 24 = 30
