scandium has 21 protons!
21
No.of protons of scandium is 21 (ATOMIC NUMBER) ATOMIC NO=no.of proton or electron MASS NO=no of proton+ no.of neutron
21
To find the total number of protons in a sample of scandium with a mass of 7.9027 g, you need to divide the mass by the atomic mass of scandium. The atomic mass of scandium is approximately 44.96 g/mol. So, 7.9027 g / 44.96 g/mol = ~0.176 mol of scandium. Since there is 1 proton in the nucleus of each scandium atom, the total number of protons would be ~0.176 mol.
Because its atomic number is 21, it has 21 protons, 21 neutrons, and 21 electrons.
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.
As all other chemical elements scandium atom has a nucleus (containing protons and neutrons) and a cloud of electrons.
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.
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.
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.
Scandium is included on the periodic table of elements because it is a chemical element with unique properties, such as being a transition metal. It has an atomic number of 21, meaning it has 21 protons in its nucleus, which determines its placement in the periodic table. Scandium also has important industrial applications, such as in aerospace and electronics.
Number of neutrons = mass number - atomic number = 49 - 21 = 28
