No.of protons of scandium is 21 (ATOMIC NUMBER)
ATOMIC NO=no.of proton or electron
MASS NO=no of proton+ no.of neutron
Because its atomic number is 21, it has 21 protons, 21 neutrons, and 21 electrons.
Sc is actually atomic number 21, there are 21 protons, 21 electrons, and usually 24 neutrons
18 protons 18 electrons 22 neutrons
Cesium has 55 protons, 78 neutrons, and 55 electrons.
There are 23 electrons, 28 neutrons, and 23 protons in vanadium.
Because its atomic number is 21, it has 21 protons, 21 neutrons, and 21 electrons.
Sc is actually atomic number 21, there are 21 protons, 21 electrons, and usually 24 neutrons
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.
21 protons and 24 neutrons in the only stable for. But there can be as few as 15 and as many as 39 neutrons.
18 protons 18 electrons 22 neutrons
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.
