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.
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.
If scandium has 24 neutrons how many protons does it have?
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.
What is the atomic mass of an atom with 23 protons 24 neutrons and 25 electrons?
The atomic mass of an atom is the sum of its protons and neutrons. In this case, the atom would have an atomic mass of 47 (23 protons + 24 neutrons). Electrons do not significantly contribute to the atomic mass of an atom.
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 electrons neutrons and protons are in scandium?
In the nucleus of scandium, there are 21 electrons, 24 neutrons, and 21 protons.
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 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?
Scandium has 21 protons, 24 neutrons, and 21 electrons.
Are the neutrons in scandium negative or positive?
Neutrons do not have an electric charge, so they do not have a positive or negative charge. Neutrons are neutral particles located in the nucleus of an atom. Scandium has 21 neutrons in its nucleus.
What does scandium have in it?
As all other chemical elements scandium atom has a nucleus (containing protons and neutrons) and a cloud of electrons.
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.
If scandium has 24 neutrons how many protons does it have?
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 protons neutrons and electrons are there in a neutral atom of 113In (indium's-113)?
49 protons, 64 neutrons and 49 electrons.
How many neutrons are found in the element Indium?
Indium, atomic number 49, so 49 Protons. Atomic mass 115, so 115-49 = 66 Neutrons.
How many protons neutrons and electrons are in Sc atomic number 44?
Scandium (Sc) has atomic number 21, so it has 21 protons and 21 electrons. Its most common isotope, Scandium-45, has 24 neutrons.
How many protons electrons and neutrons does In have?
Indium, (In) atom number 49, has:49 protons (same as atom number)49 electrons (same as protons in the UNcharged neutral atom)113-49=64 neutrons in In-113 isotope or 115-49=66 neutrons in In-115 isotope,both are natural occurring isotopes of In (5% and 95% respectively).
